BIS CRS Certification for LED Lighting Chains | IS 10322 (Part 5/Section 7):2017 | BIS Consultancy

Introduction

LED Lighting Chains are widely used for decorative, festive and celebratory lighting in homes, commercial establishments, events, exhibitions, hotels, shopping areas and public spaces. They are commonly known as LED string lights, decorative light chains, festival lights or Christmas lights depending on their design and application.

A lighting chain generally consists of a series of lamps, parallel-connected lamps, or series/parallel-connected lamps connected through insulated conductors. BIS describes lighting chains as an assembly of lamps and interconnecting insulated conductors, with decorative festival and celebratory lights being typical examples.

The earlier BIS CRS framework for this product was based on:

IS 10322 (Part 5/Sec 7):2017 / IEC 60598-2-20:2014 – Luminaires – Part 5: Particular Requirements – Section 7: Lighting Chains.

BIS's CRS database specifically identifies LED Lighting Chains against this standard.

Important Current Update for 2026

BIS has now revised the standard to:

IS 10322 (Part 5/Sec 7):2026 / IEC 60598-2-20:2022

for LED Lighting Chains. BIS issued implementation guidelines dated 20 March 2026, stating that the 2017 standard and the new 2026 standard could run concurrently only up to 2 August 2026. From 3 August 2026, new licences cannot be granted under the old 2017 standard. Existing licensees were required to implement the revised standard by the same date.

Therefore, this article covers the 2017 standard because it remains an important search and legacy reference, while clearly explaining the current 2026 compliance position.

Qualitance India provides BIS CRS consultancy for LED Lighting Chains, including product classification, laboratory coordination, technical documentation, CRS application support and transition assistance to the revised 2026 standard.

What Is IS 10322 (Part 5/Section 7):2017?

IS 10322 (Part 5/Sec 7):2017 is the Indian Standard for:

Luminaires – Part 5: Particular Requirements – Section 7: Lighting Chains

The BIS uniform test-report format identifies the corresponding international reference as:

IEC 60598-2-20:2014

and uses the test report form:

BIS_LUM/LC_IS10322-5-7_V1.0.

The standard specifies particular requirements for lighting chains relating to:

Classification
Construction
Marking
Creepage distances and clearances
Earthing
Terminals
External and internal wiring
Protection against electric shock
Endurance and thermal tests
Resistance to dust and moisture
Insulation resistance
Electric strength
Resistance to heat, fire and tracking
Interconnecting connectors

What Is an LED Lighting Chain?

A lighting chain is an electrical lighting assembly consisting of lamps connected in series, parallel or series/parallel arrangements with interconnecting insulated conductors.

Examples include:

Decorative LED string lights
Christmas lights
Festival lights
Celebration lighting chains
Decorative indoor light chains
Decorative outdoor light chains
Event lighting chains
Seasonal decorative lighting
LED chain lights used for architectural decoration

The exact product classification depends on the actual construction and intended use.

LED Lighting Chains Under BIS CRS

BIS identifies LED Lighting Chains under the Compulsory Registration Scheme.

The official BIS CRS standard table lists:

IS 10322 (Part 5/Sec 7):2017 / IEC 60598-2-20:2014 – LED Lighting Chains

and also separately lists the revised:

IS 10322 (Part 5/Sec 7):2026 – LED Lighting Chains.

The original MeitY framework also specifically addressed LED Lighting Chains as part of the compulsory registration regime. MeitY's guidance confirms that lighting chains are within the CRO scope.

Implementation of LED Lighting Chains Under CRS

LED Lighting Chains were brought under the compulsory-registration framework through the Electronics and Information Technology goods regulatory framework.

The MeitY material identifies LED Lighting Chains under the relevant IS 10322 Part 5 Section 7 category.

BIS's current CRS database continues to identify the product category and now records both the 2017 and revised 2026 standards.

Current Status of IS 10322 (Part 5/Sec 7):2017

This is an important section for manufacturers.

BIS's Guidelines for Implementation of Revised Standards for LED Luminaires, dated 20 March 2026, state:

Current Standard: IS 10322 (Part 5/Sec 7):2017

Revised Standard: IS 10322 (Part 5/Sec 7):2026 / IEC 60598-2-20:2022

Last date of concurrent running: 2 August 2026.

For existing licensees:

Compliance with the revised standard had to be implemented by 2 August 2026.
Complete test reports from BIS-recognized laboratories were required for lead models previously tested under the old standard.
An undertaking regarding implementation in other existing series models was also required.
Failure to complete the required transition actions could lead to licence cancellation or deletion of models from the licence scope.

For new applicants:

Applications already having samples submitted/test reports issued could continue under the old standard during the transition.
New applications could be processed under the old or revised standard only up to 2 August 2026.
Beyond 2 August 2026, no new licence can be granted under the old standard.

What This Means for Manufacturers Today

For a new BIS CRS application in September 2026, manufacturers should plan against:

IS 10322 (Part 5/Sec 7):2026 / IEC 60598-2-20:2022

rather than starting a new application under the 2017 edition.

What Changed in the 2026 Standard?

BIS identifies several specific changes for Section 7.

The revised IS 10322 (Part 5/Sec 7):2026 introduces:

Specific provisions for Temporarily Installed Protected Lighting (TPL) chains
New terms and definitions
Updated references to IS 10322 Part 1
Use of the revised Part 1 framework.

The revised 2026 standard is aligned with:

IEC 60598-2-20:2022

rather than the 2014 edition referenced by the 2017 Indian Standard.

Main Safety Requirements Under the 2017 Standard

For historical/legacy 2017 certification and transition understanding, the major requirements included:

General test requirements
Classification
Marking
Construction
Creepage distances and clearances
Provision for earthing
Terminals
External and internal wiring
Protection against electric shock
Endurance tests
Thermal tests
Resistance to dust and moisture
Insulation resistance
Electric strength
Resistance to heat, fire and tracking

BIS laboratory listings continue to show these clause-wise requirements for the 2017 version.

Classification of LED Lighting Chains

Under the 2017 framework, lighting chains are classified according to the type of protection against electric shock.

The BIS product information identifies:

Class II Lighting Chains

Products designed with protection against electric shock based on double or reinforced insulation rather than protective earthing.

Class III Lighting Chains

Products designed for operation at Safety Extra-Low Voltage or the applicable low-voltage safety arrangement.

BIS's technical product description specifically identifies Class II and Class III lighting chains.

The exact classification must be established according to the product's electrical design.

Construction Requirements

Construction is a major part of lighting-chain safety.

The product should be designed so that:

Electrical connections are secure
Live parts are properly protected
Components are suitably enclosed
Wiring is properly routed
Mechanical stress does not create unsafe conditions
Control devices are safely enclosed
The chain remains safe during intended use

BIS notes that control units and similar devices integral to lighting chains should be enclosed in non-flammable insulating material and securely fixed to the cable.

Protection Against Electrification of Decorations

One important feature of lighting-chain safety is prevention of hazardous energization of nearby decorative metallic materials.

BIS specifically states that:

Lighting chains shall not electrify tinsel or other metallic decorations with which they are used.

This requirement is particularly relevant for festive and decorative lighting applications where chains may be installed around metallic decorative objects.

Cable Requirements for Lighting Chains

The BIS technical description for the 2017 standard states that the cable used is single-core and may have:

PVC insulation
Rubber insulation

For Class II chains, the cable requirements reference the relevant requirements of IEC 60227 or IEC 60245.

For Class III chains, the cable should meet the applicable insulation requirements specified for Class III chains.

Cable Length Requirements

The 2017 test-report format includes specific cable requirements.

For outdoor use:

A splash-proof plug or permanent connection is required as applicable.
The length between the plug and the first lamp or lampholder is required to be at least 1.5 m.

The test report also records maximum lengths for extendable Class II lighting chains:

100 m for 0.5 mm² cable
150 m for 0.75 mm² cable

These are requirements appearing in the published 2017 test-report format.

Creepage Distances and Clearances

Creepage distance and clearance requirements are important for preventing unintended electrical arcing and surface leakage.

The BIS laboratory testing framework identifies Clause 20.8 – Creepage Distance and Clearances for the 2017 standard.

The required distances depend on:

Working voltage
Insulation type
Pollution conditions
Material characteristics
Product construction

Manufacturers should verify the applicable values using the relevant standard.

Provision for Earthing

Where earthing is applicable, the product's protective-earth arrangement is evaluated.

BIS laboratory listings identify Provision for Earthing as a specific test/inspection area for the 2017 lighting-chain standard.

Products classified as Class II have different protection arrangements from products requiring protective earthing.

External and Internal Wiring

The wiring system must be designed and assembled so that it remains safe during operation.

Testing/inspection can cover:

Wire type
Insulation
Cross-sectional area
Connection quality
Wire routing
Mechanical protection
Strain protection
Terminal connections

The published 2017 test-report format specifically records cable properties and mechanical requirements.

Protection Against Electric Shock

The product must prevent users from coming into contact with dangerous live parts during intended use.

BIS identifies:

Clause 20.12 – Protection against electric shock

as part of the lighting-chain testing framework.

This can include evaluation of:

Accessibility of live parts
Insulation
Connectors
Plugs
Lampholders
Divisible connections
Decorative-metal electrification risks

Endurance and Thermal Tests

Endurance and thermal performance are particularly important for decorative lighting because chains may operate for long periods.

The BIS technical description explains that endurance and thermal testing represent cyclic heating and cooling conditions encountered in service, and the luminaire/wiring should not become unsafe under those conditions.

BIS laboratory listings identify:

Clause 20.13 – Endurance Tests and Thermal Tests

for the 2017 standard.

Resistance to Dust and Moisture

Outdoor or exposed lighting chains may encounter humidity, rain, splashing or dust.

The 2017 BIS test framework includes:

Clause 20.14 – Resistance to Dust & Moisture.

The applicable protection requirements depend on the product construction and intended use.

Insulation Resistance and Electric Strength

Electrical insulation must withstand the required electrical stresses.

The 2017 testing framework includes:

Clause 20.15 – Insulation Resistance and Electric Strength.

These tests are intended to assess whether the insulation system provides adequate protection during operation.

Resistance to Heat, Fire and Tracking

Materials used within lighting chains can be exposed to heat generated by lamps, control devices and electrical components.

The 2017 standard includes:

Clause 20.16 – Resistance to Heat, Fire and Tracking.

This helps assess whether relevant materials remain safe under specified thermal and electrical conditions.

Interconnecting Connectors

The 2017 standard includes a dedicated Annex A for requirements relating to interconnecting connectors used in lighting chains.

The BIS test-report format covers matters such as:

Connector classification
Connector style
Additional characteristics
Identification
Non-accessibility of live parts
Polarization
Prevention of improper connection
Compatibility between different connector systems
Prevention of unsafe connection to other plug/socket systems.

Manufacturers using detachable or interconnecting connectors should therefore pay particular attention to the connector design.

Marking Requirements

The 2017 BIS product information states that lighting chains should carry information such as:

Rated voltage
Wattage

BIS identifies marking as a specific conformity requirement.

For CRS products, applicable self-declaration marking requirements also have to be followed according to the current BIS/CRS procedure.

BIS CRS Testing for LED Lighting Chains

Testing must be performed through a laboratory having the applicable BIS-recognized testing scope.

The BIS LIMS database currently contains multiple laboratory entries for the lighting-chain standard. Recognized laboratories listed by BIS include facilities such as:

Electronic Regional Test Laboratory (North), Delhi
Intertek India, New Delhi
UL India, Gurugram
National Test House
Other BIS-recognized laboratories with the applicable scope.

Before submission, manufacturers should check the current laboratory scope because the revised 2026 standard is now the applicable route for new applications.

Sample Requirement for LED Lighting Chains

The exact number and configuration of test samples should be confirmed with the selected BIS-recognized laboratory before submission.

Sample selection can depend on:

Product construction
Class II or Class III design
Rated voltage
Control arrangement
Connector arrangement
Outdoor/indoor intended use
Product series
Model configuration

BIS CRS procedures require the applicant to submit the product for testing to a BIS-recognized laboratory according to the applicable guidelines and testing requirements.

Manufacturers should avoid dispatching samples before the laboratory confirms the current applicable standard and sample arrangement.

BIS CRS Registration Process for LED Lighting Chains

Step 1 – Product Classification

Determine whether the product is a lighting chain and identify:

Class
Voltage
Wattage
Indoor/outdoor use
Connector configuration
Control unit
Lamp type
Model/series

Step 2 – Applicable Standard Verification

For a new application after 2 August 2026, verify the applicable revised standard:

IS 10322 (Part 5/Sec 7):2026 / IEC 60598-2-20:2022.

Step 3 – Manufacturer Verification

The actual manufacturing unit must be correctly identified.

Step 4 – Brand and Model Finalisation

Finalize the:

Manufacturer + Brand + Product + Model + Technical Configuration

before laboratory testing.

Step 5 – Obtain CRS Login

The manufacturer follows the BIS CRS procedure to obtain/login with the required credentials.

Step 6 – Generate Test Request

The manufacturer enters sample details and selects an approved laboratory through the CRS system.

Step 7 – Submit Sample

The product sample and Test Request are submitted to the selected laboratory.

BIS currently instructs applicants to send the sample and Test Request within 60 days of Test Request generation.

Step 8 – Product Testing

The laboratory tests the LED Lighting Chain against the applicable standard.

Step 9 – Test Report

The laboratory issues the applicable test report.

Step 10 – Verify Test Report

The report is verified on the CRS portal.

Step 11 – Online Application

The manufacturer submits the registration application using the verified report.

Step 12 – Documents and Undertaking

The required technical, legal, manufacturer, brand and undertaking documents are submitted.

Step 13 – BIS Scrutiny

BIS examines the application.

Step 14 – Clarification

Any query raised by BIS is addressed with appropriate supporting documents.

Step 15 – CRS Registration

After satisfactory processing, BIS grants registration for the approved scope.

Test Report Validity

The current BIS CRS instructions state that the test report submitted at the time of online application should not be more than 90 days old.

This means manufacturers should plan testing and application submission carefully.

For a revised-standard application, the report should also correspond to the standard applicable to the application.

BIS Documents Required for LED Lighting Chains

Common documents may include:

Manufacturer business licence
Factory name and address proof
Product technical specification
Product photographs
Rating label
User manual
Circuit diagram
Block diagram
PCB details, where applicable
Control-unit details
LED/lamp specifications
Cable specifications
Connector specifications
Critical component list
Power supply information
Transformer information, where applicable
Test report from BIS-recognized laboratory
Brand registration certificate
Brand authorization letter, where applicable
Authorized signatory details
Affidavit-cum-undertaking
Other documents specified by BIS

BIS requires evidence establishing the manufacturing unit's name and address and applicable manufacturing activity for CRS login/application.

Requirements for Foreign Manufacturers

Foreign manufacturers without a liaison office or branch office in India generally need to appoint an Authorized Indian Representative (AIR).

BIS's current CRS instructions expressly require such foreign applicants to appoint an AIR according to the prescribed BIS procedure.

The AIR arrangement should be completed before proceeding with the CRS application.

Requirements for Indian Manufacturers

Indian manufacturers should ensure that:

Factory name is correct
Factory address is correct
Brand is correctly documented
Model number is final
Product description is consistent
Test report matches the product
Label matches the application
Technical documentation is complete

Consistency between the sample, test report and application is important for avoiding clarification.

Brand Requirements

LED Lighting Chains can be manufactured under:

Manufacturer-owned brand
OEM brand
Private-label brand
Third-party brand

Where another entity owns the brand, the applicable authorization documents should be prepared.

BIS's CRS process includes brand registration and authorization documentation where applicable.

Model and Series Considerations

A manufacturer may have several LED Lighting Chain models with differences in:

Number of LEDs
Cable length
Wattage
Voltage
Control unit
Flashing modes
Connector
Plug
Enclosure
Indoor/outdoor configuration
Waterproofing
Cable size

Model-series coverage should be reviewed before testing.

BIS allows registered manufacturers to request inclusion of new models of the same product and brand under the same registration, subject to the applicable procedure. The current inclusion procedure states that the relevant test report should be within 90 days of issue at online submission.

Electrical Safety of LED Lighting Chains

Electrical safety is a major focus of the applicable standard.

Important design areas include:

Operating voltage
Insulation
Wiring
Clearances
Creepage distances
Earthing where applicable
Connectors
Plugs
Control units
Enclosures
Strain relief
Protection against electric shock

Manufacturers should finalize the electrical architecture before testing.

Outdoor LED Lighting Chains

Outdoor lighting chains require particular attention to:

Moisture protection
Plug construction
Cable insulation
Connector protection
Enclosure
Strain relief
Water ingress
Mechanical durability

The 2017 test-report format specifically records requirements for splash-proof plugs or permanent connections when the chain is intended for outdoor use.

The applicable moisture and protection requirements under the current 2026 standard should be verified with the testing laboratory.

LED Lighting Chains with Control Units

Many decorative lighting chains include:

Flashing controller
Mode selector
Remote-control receiver
Electronic control unit
Dimming function

Where the control unit forms an integral part of the lighting chain, BIS's product description requires it to be enclosed in non-flammable insulating material and securely fixed to the cable.

The control architecture should therefore be properly documented before testing.

LED Lighting Chains with Interconnecting Connectors

Where a lighting chain includes detachable or extendable connectors, connector safety becomes important.

The 2017 Annex A contains specific requirements for:

Live-part accessibility
Polarization
Compatibility
Prevention of improper connection
Interconnection safety.

Manufacturers should provide complete connector specifications and photographs to the laboratory.

Product Label and CRS Marking

For CRS products, the self-declaration marking requirements must be followed according to the current BIS procedure.

BIS's CRS FAQ states that the declaration should preferably be marked on the product, but where product size makes this impractical it may be marked on the packaging. The marking should be indelible, legible and visible.

For the lighting-chain product itself, the applicable standard information can include rated voltage and wattage under the relevant product requirements.

BIS Testing Charges for LED Lighting Chains

Testing charges vary by laboratory.

The BIS LIMS database still displays several legacy 2017 testing entries. Examples include:

₹30,000 at Atharva Laboratories, Noida
₹33,000 at Vardhamana Testing Laboratory
₹40,000 at another current laboratory entry
₹45,000 at Planet Electro Labs
₹50,000 at other listed laboratories
₹55,000 at Bluesky Lab, Ghaziabad
₹56,625 at another current laboratory listing
₹75,000 at another listed laboratory.

These are laboratory-specific charges excluding applicable taxes.

Important 2026 Cost Note

For the revised IS 10322 (Part 5/Sec 7):2026, current BIS LIMS listings also show different laboratory-specific charges, including examples of:

₹20,000
₹35,000
₹50,000
₹55,000
₹71,500
₹75,000
₹85,000
₹1,50,000

depending on the laboratory and test scope.

Because the 2017 standard's concurrent period ended on 2 August 2026, manufacturers starting a new application now should obtain a quotation against the 2026 standard rather than budgeting solely on legacy 2017 pricing.

What Is the Total Cost of BIS CRS Registration?

Laboratory testing is only one component.

The total project cost can include:

Laboratory testing
BIS registration-related charges
Sample transportation
Technical documentation
Brand authorization
AIR support for foreign manufacturers
Additional testing
Retesting, if required
Consultant charges

The final cost depends on the product design, number of models, laboratory and current BIS requirements.

How Long Does BIS CRS Registration Take?

The overall timeline depends on:

Product readiness
Laboratory availability
Testing duration
Documentation completeness
Test result
Application accuracy
BIS scrutiny
Query resolution

BIS's current CRS process states that the test report should be within 90 days at online application, while the sample and Test Request should be sent to the laboratory within 60 days of Test Request generation.

Therefore, manufacturers should avoid unnecessary delay between testing and application submission.

Common Reasons for BIS CRS Delays

Incorrect Standard Version

Starting a new application under the 2017 standard after the 2 August 2026 transition date can create a regulatory problem.

Incorrect Product Classification

The product should correctly fall within the lighting-chain category.

Model Mismatch

The model in the report should match the model in the application.

Brand Mismatch

Brand information should remain consistent.

Manufacturing Address Mismatch

Factory details should match supporting documentation.

Non-Conforming Sample

The lighting chain must comply with the applicable safety requirements.

Connector Problems

Interconnecting connectors can create safety issues if live parts, polarization or compatibility requirements are not satisfied.

Cable Problems

Cable type, insulation, cross-sectional area or length may not satisfy applicable requirements.

Outdoor Use Without Appropriate Protection

Outdoor products require appropriate moisture and connection arrangements.

Incomplete Technical File

Missing circuit diagrams, control-unit information, component details or product specifications can cause queries.

Old Test Report

The current BIS CRS system requires a report not more than 90 days old at online submission.

Is Factory Inspection Required Under BIS CRS?

BIS CRS follows a registration-and-testing model and differs from the conventional Scheme-I ISI Mark product-certification process.

The primary basis is the recognized-laboratory test report and documentary registration process.

Manufacturers should nevertheless maintain consistent product quality and ensure that registered products remain compliant with the applicable requirements.

BIS CRS Renewal for LED Lighting Chains

CRS registration must be managed according to the applicable renewal process.

BIS provides an online renewal mechanism through the CRS portal.

Manufacturers should monitor:

Registration validity
Product models
Brand
Manufacturing location
Product modifications
Current applicable standard

Difference Between BIS CRS Registration and BIS ISI Mark Certification

BIS CRS Registration and conventional BIS ISI Mark certification are different conformity-assessment systems.

BIS CRS Registration

Used for specified electronic and IT products and based primarily on laboratory testing and registration.

BIS Scheme-I / ISI Mark

Used for specified products under the BIS product-certification framework and generally involves broader manufacturing and continuing-conformity requirements.

LED Lighting Chains covered by the MeitY CRS framework follow the CRS registration route.

Conclusion

LED Lighting Chains are an important category of decorative lighting products and are covered under the BIS Compulsory Registration Scheme framework. The earlier applicable Indian Standard was IS 10322 (Part 5/Sec 7):2017 / IEC 60598-2-20:2014, which addressed lighting-chain construction, classification, wiring, protection against electric shock, endurance and thermal performance, moisture resistance, insulation, electric strength and resistance to heat, fire and tracking.

The 2017 framework also contained important requirements for Class II and Class III lighting chains, cable construction, outdoor-use connections, maximum extendable lengths and interconnecting connectors.

However, the regulatory position has now changed. BIS revised the standard to IS 10322 (Part 5/Sec 7):2026 / IEC 60598-2-20:2022 and specified 2 August 2026 as the last date of concurrent running. BIS states that no new licence can be granted under the 2017 standard after that date, while existing licensees were required to implement the revised standard by the same deadline.

The revised 2026 standard introduces specific provisions for Temporarily Installed Protected Lighting (TPL) chains, new terminology and updated references to IS 10322 Part 1.

Therefore, manufacturers planning a new BIS CRS application today should use the 2026 standard and confirm the current laboratory testing scope before submitting samples.

BIS LIMS continues to show laboratory-specific testing charges for the legacy 2017 version as well as the revised 2026 version. The charges vary substantially between laboratories, so the exact quotation should be confirmed according to the applicable current standard and product configuration.
