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

Therefore, this article covers the 2017 standard because it remains an important search and legacy reference<\/strong>, while clearly explaining the current 2026 compliance position<\/strong>.<\/p>\n

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.<\/p>\n

\n
\n<\/div>\n
Classification of LED Lighting Chains<\/h1>\n
Under the 2017 framework, lighting chains are classified according to the type of protection against electric shock.<\/p>\n
The BIS product information identifies:<\/p>\n
Class II Lighting Chains<\/h3>\n
Products designed with protection against electric shock based on double or reinforced insulation rather than protective earthing.<\/p>\n
Class III Lighting Chains<\/h3>\n
Products designed for operation at Safety Extra-Low Voltage or the applicable low-voltage safety arrangement.<\/p>\n
BIS’s technical product description specifically identifies Class II and Class III lighting chains.<\/p>\n
The exact classification must be established according to the product’s electrical design.<\/p>\n
\n
\n<\/div>\n
Construction Requirements<\/h1>\n
Construction is a major part of lighting-chain safety.<\/p>\n
The product should be designed so that:<\/p>\n
\n
Electrical connections are secure<\/li>\n
Live parts are properly protected<\/li>\n
Components are suitably enclosed<\/li>\n
Wiring is properly routed<\/li>\n
Mechanical stress does not create unsafe conditions<\/li>\n
Control devices are safely enclosed<\/li>\n
The chain remains safe during intended use<\/li>\n<\/ul>\n
BIS notes that control units and similar devices integral to lighting chains should be enclosed in non-flammable insulating material<\/strong> and securely fixed to the cable.<\/p>\n
\n
\n<\/div>\n
Protection Against Electrification of Decorations<\/h1>\n
One important feature of lighting-chain safety is prevention of hazardous energization of nearby decorative metallic materials.<\/p>\n
BIS specifically states that:<\/p>\n
Lighting chains shall not electrify tinsel or other metallic decorations with which they are used.<\/strong><\/p>\n
This requirement is particularly relevant for festive and decorative lighting applications where chains may be installed around metallic decorative objects.<\/p>\n
\n
\n<\/div>\n
Cable Requirements for Lighting Chains<\/h1>\n
The BIS technical description for the 2017 standard states that the cable used is single-core<\/strong> and may have:<\/p>\n
\n
PVC insulation<\/li>\n
Rubber insulation<\/li>\n<\/ul>\n
For Class II chains, the cable requirements reference the relevant requirements of IEC 60227 or IEC 60245<\/strong>.<\/p>\n
For Class III chains, the cable should meet the applicable insulation requirements specified for Class III chains.<\/p>\n
\n
\n<\/div>\n
Cable Length Requirements<\/h1>\n
The 2017 test-report format includes specific cable requirements.<\/p>\n
For outdoor use:<\/p>\n
\n
A splash-proof plug or permanent connection is required as applicable.<\/li>\n
The length between the plug and the first lamp or lampholder is required to be at least 1.5 m<\/strong>.<\/li>\n<\/ul>\n
The test report also records maximum lengths for extendable Class II lighting chains:<\/p>\n
\n
100 m<\/strong> for 0.5 mm\u00b2 cable<\/li>\n
150 m<\/strong> for 0.75 mm\u00b2 cable<\/li>\n<\/ul>\n
These are requirements appearing in the published 2017 test-report format.<\/p>\n
\n
\n<\/div>\n
Creepage Distances and Clearances<\/h1>\n
Creepage distance and clearance requirements are important for preventing unintended electrical arcing and surface leakage.<\/p>\n
The BIS laboratory testing framework identifies Clause 20.8 \u2013 Creepage Distance and Clearances<\/strong> for the 2017 standard.<\/p>\n
The required distances depend on:<\/p>\n
\n
Working voltage<\/li>\n
Insulation type<\/li>\n
Pollution conditions<\/li>\n
Material characteristics<\/li>\n
Product construction<\/li>\n<\/ul>\n
Manufacturers should verify the applicable values using the relevant standard.<\/p>\n
\n
\n<\/div>\n
Provision for Earthing<\/h1>\n
Where earthing is applicable, the product’s protective-earth arrangement is evaluated.<\/p>\n
BIS laboratory listings identify Provision for Earthing<\/strong> as a specific test\/inspection area for the 2017 lighting-chain standard.<\/p>\n
Products classified as Class II have different protection arrangements from products requiring protective earthing.<\/p>\n
\n
\n<\/div>\n
External and Internal Wiring<\/h1>\n
The wiring system must be designed and assembled so that it remains safe during operation.<\/p>\n

Lampholders<\/li>\n
Divisible connections<\/li>\n
Decorative-metal electrification risks<\/li>\n<\/ul>\n
\n
\n<\/div>\n
Endurance and Thermal Tests<\/h1>\n
Endurance and thermal performance are particularly important for decorative lighting because chains may operate for long periods.<\/p>\n
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.<\/p>\n
BIS laboratory listings identify:<\/p>\n
Clause 20.13 \u2013 Endurance Tests and Thermal Tests<\/strong><\/p>\n
for the 2017 standard.<\/p>\n
\n
\n<\/div>\n
Resistance to Dust and Moisture<\/h1>\n
Outdoor or exposed lighting chains may encounter humidity, rain, splashing or dust.<\/p>\n
The 2017 BIS test framework includes:<\/p>\n
Clause 20.14 \u2013 Resistance to Dust & Moisture.<\/strong><\/p>\n
The applicable protection requirements depend on the product construction and intended use.<\/p>\n
\n
\n<\/div>\n
Insulation Resistance and Electric Strength<\/h1>\n
Electrical insulation must withstand the required electrical stresses.<\/p>\n
The 2017 testing framework includes:<\/p>\n
Clause 20.15 \u2013 Insulation Resistance and Electric Strength.<\/strong><\/p>\n
These tests are intended to assess whether the insulation system provides adequate protection during operation.<\/p>\n
\n
\n<\/div>\n
Resistance to Heat, Fire and Tracking<\/h1>\n
Materials used within lighting chains can be exposed to heat generated by lamps, control devices and electrical components.<\/p>\n
The 2017 standard includes:<\/p>\n
Clause 20.16 \u2013 Resistance to Heat, Fire and Tracking.<\/strong><\/p>\n
This helps assess whether relevant materials remain safe under specified thermal and electrical conditions.<\/p>\n
\n
\n<\/div>\n
Interconnecting Connectors<\/h1>\n
The 2017 standard includes a dedicated Annex A<\/strong> for requirements relating to interconnecting connectors used in lighting chains.<\/p>\n
The BIS test-report format covers matters such as:<\/p>\n
\n
Connector classification<\/li>\n
Connector style<\/li>\n
Additional characteristics<\/li>\n
Identification<\/li>\n
Non-accessibility of live parts<\/li>\n
Polarization<\/li>\n
Prevention of improper connection<\/li>\n
Compatibility between different connector systems<\/li>\n
Prevention of unsafe connection to other plug\/socket systems.<\/li>\n<\/ul>\n
Manufacturers using detachable or interconnecting connectors should therefore pay particular attention to the connector design.<\/p>\n
\n
\n<\/div>\n
Marking Requirements<\/h1>\n
The 2017 BIS product information states that lighting chains should carry information such as:<\/p>\n
\n
Rated voltage<\/li>\n
Wattage<\/li>\n<\/ul>\n
BIS identifies marking<\/strong> as a specific conformity requirement.<\/p>\n
For CRS products, applicable self-declaration marking requirements also have to be followed according to the current BIS\/CRS procedure.<\/p>\n
\n
\n<\/div>\n
BIS CRS Testing for LED Lighting Chains<\/h1>\n
Testing must be performed through a laboratory having the applicable BIS-recognized testing scope.<\/p>\n

Wiring<\/li>\n
Clearances<\/li>\n
Creepage distances<\/li>\n
Earthing where applicable<\/li>\n
Connectors<\/li>\n
Plugs<\/li>\n
Control units<\/li>\n
Enclosures<\/li>\n
Strain relief<\/li>\n
Protection against electric shock<\/li>\n<\/ul>\n
Manufacturers should finalize the electrical architecture before testing.<\/p>\n
\n
\n<\/div>\n
Outdoor LED Lighting Chains<\/h1>\n
Outdoor lighting chains require particular attention to:<\/p>\n
\n
Moisture protection<\/li>\n

Cable insulation<\/li>\n
Connector protection<\/li>\n
Enclosure<\/li>\n
Strain relief<\/li>\n
Water ingress<\/li>\n
Mechanical durability<\/li>\n<\/ul>\n
The 2017 test-report format specifically records requirements for splash-proof plugs or permanent connections when the chain is intended for outdoor use.<\/p>\n
The applicable moisture and protection requirements under the current 2026 standard should be verified with the testing laboratory.<\/p>\n
\n
\n<\/div>\n
LED Lighting Chains with Control Units<\/h1>\n
Many decorative lighting chains include:<\/p>\n
\n
Flashing controller<\/li>\n
Mode selector<\/li>\n
Remote-control receiver<\/li>\n
Electronic control unit<\/li>\n
Dimming function<\/li>\n<\/ul>\n
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.<\/p>\n
The control architecture should therefore be properly documented before testing.<\/p>\n
\n
\n<\/div>\n
LED Lighting Chains with Interconnecting Connectors<\/h1>\n
Where a lighting chain includes detachable or extendable connectors, connector safety becomes important.<\/p>\n
The 2017 Annex A contains specific requirements for:<\/p>\n
\n
Live-part accessibility<\/li>\n
Polarization<\/li>\n
Compatibility<\/li>\n
Prevention of improper connection<\/li>\n
Interconnection safety.<\/li>\n<\/ul>\n
Manufacturers should provide complete connector specifications and photographs to the laboratory.<\/p>\n
\n
\n<\/div>\n
Product Label and CRS Marking<\/h1>\n
For CRS products, the self-declaration marking requirements must be followed according to the current BIS procedure.<\/p>\n
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.<\/p>\n
For the lighting-chain product itself, the applicable standard information can include rated voltage and wattage under the relevant product requirements.<\/p>\n
\n
\n<\/div>\n
BIS Testing Charges for LED Lighting Chains<\/h1>\n
Testing charges vary by laboratory.<\/p>\n
The BIS LIMS database still displays several legacy 2017 testing entries. Examples include:<\/p>\n
\n
\u20b930,000<\/strong> at Atharva Laboratories, Noida<\/li>\n
\u20b933,000<\/strong> at Vardhamana Testing Laboratory<\/li>\n
\u20b940,000<\/strong> at another current laboratory entry<\/li>\n
\u20b945,000<\/strong> at Planet Electro Labs<\/li>\n
\u20b950,000<\/strong> at other listed laboratories<\/li>\n
\u20b955,000<\/strong> at Bluesky Lab, Ghaziabad<\/li>\n
\u20b956,625<\/strong> at another current laboratory listing<\/li>\n
\u20b975,000<\/strong> at another listed laboratory.<\/li>\n<\/ul>\n
These are laboratory-specific charges excluding applicable taxes<\/strong>.<\/p>\n
Important 2026 Cost Note<\/h3>\n
For the revised IS 10322 (Part 5\/Sec 7):2026<\/strong>, current BIS LIMS listings also show different laboratory-specific charges, including examples of:<\/p>\n
\n
\u20b920,000<\/strong><\/li>\n
\u20b935,000<\/strong><\/li>\n
\u20b950,000<\/strong><\/li>\n
\u20b955,000<\/strong><\/li>\n
\u20b971,500<\/strong><\/li>\n
\u20b975,000<\/strong><\/li>\n
\u20b985,000<\/strong><\/li>\n
\u20b91,50,000<\/strong><\/li>\n<\/ul>\n
depending on the laboratory and test scope.<\/p>\n
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<\/strong> rather than budgeting solely on legacy 2017 pricing.<\/p>\n
\n
\n<\/div>\n
What Is the Total Cost of BIS CRS Registration?<\/h1>\n
Laboratory testing is only one component.<\/p>\n
The total project cost can include:<\/p>\n

The final cost depends on the product design, number of models, laboratory and current BIS requirements.<\/p>\n
\n
\n<\/div>\n
How Long Does BIS CRS Registration Take?<\/h1>\n
The overall timeline depends on:<\/p>\n
\n
Product readiness<\/li>\n
Laboratory availability<\/li>\n
Testing duration<\/li>\n
Documentation completeness<\/li>\n
Test result<\/li>\n
Application accuracy<\/li>\n
BIS scrutiny<\/li>\n
Query resolution<\/li>\n<\/ul>\n
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.<\/p>\n
Therefore, manufacturers should avoid unnecessary delay between testing and application submission.<\/p>\n
\n
\n<\/div>\n
Common Reasons for BIS CRS Delays<\/h1>\n
Incorrect Standard Version<\/h2>\n
Starting a new application under the 2017 standard after the 2 August 2026 transition date can create a regulatory problem.<\/p>\n
Incorrect Product Classification<\/h2>\n
The product should correctly fall within the lighting-chain category.<\/p>\n
Model Mismatch<\/h2>\n
The model in the report should match the model in the application.<\/p>\n
Brand Mismatch<\/h2>\n
Brand information should remain consistent.<\/p>\n
Manufacturing Address Mismatch<\/h2>\n
Factory details should match supporting documentation.<\/p>\n
Non-Conforming Sample<\/h2>\n
The lighting chain must comply with the applicable safety requirements.<\/p>\n
Connector Problems<\/h2>\n
Interconnecting connectors can create safety issues if live parts, polarization or compatibility requirements are not satisfied.<\/p>\n
Cable Problems<\/h2>\n
Cable type, insulation, cross-sectional area or length may not satisfy applicable requirements.<\/p>\n
Outdoor Use Without Appropriate Protection<\/h2>\n
Outdoor products require appropriate moisture and connection arrangements.<\/p>\n
Incomplete Technical File<\/h2>\n
Missing circuit diagrams, control-unit information, component details or product specifications can cause queries.<\/p>\n
Old Test Report<\/h2>\n
The current BIS CRS system requires a report not more than 90 days old at online submission.<\/p>\n
\n
\n<\/div>\n
Is Factory Inspection Required Under BIS CRS?<\/h1>\n
BIS CRS follows a registration-and-testing model and differs from the conventional Scheme-I ISI Mark product-certification process.<\/p>\n
The primary basis is the recognized-laboratory test report and documentary registration process.<\/p>\n
Manufacturers should nevertheless maintain consistent product quality and ensure that registered products remain compliant with the applicable requirements.<\/p>\n
\n
\n<\/div>\n
BIS CRS Renewal for LED Lighting Chains<\/h1>\n
CRS registration must be managed according to the applicable renewal process.<\/p>\n
BIS provides an online renewal mechanism through the CRS portal.<\/p>\n
Manufacturers should monitor:<\/p>\n
\n
Registration validity<\/li>\n
Product models<\/li>\n
Brand<\/li>\n
Manufacturing location<\/li>\n
Product modifications<\/li>\n
Current applicable standard<\/li>\n<\/ul>\n
\n
\n<\/div>\n
Difference Between BIS CRS Registration and BIS ISI Mark Certification<\/h1>\n
BIS CRS Registration and conventional BIS ISI Mark certification are different conformity-assessment systems.<\/p>\n
BIS CRS Registration<\/h3>\n
Used for specified electronic and IT products and based primarily on laboratory testing and registration.<\/p>\n
BIS Scheme-I \/ ISI Mark<\/h3>\n
Used for specified products under the BIS product-certification framework and generally involves broader manufacturing and continuing-conformity requirements.<\/p>\n

Conclusion<\/h1>\n
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<\/strong>, 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.<\/p>\n
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<\/strong>.<\/p>\n
However, the regulatory position has now changed. BIS revised the standard to IS 10322 (Part 5\/Sec 7):2026 \/ IEC 60598-2-20:2022<\/strong> and specified 2 August 2026<\/strong> 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.<\/p>\n
The revised 2026 standard introduces specific provisions for Temporarily Installed Protected Lighting (TPL) chains<\/strong>, new terminology and updated references to IS 10322 Part 1.<\/p>\n
Therefore, manufacturers planning a new BIS CRS application today should use the 2026 standard<\/strong> and confirm the current laboratory testing scope before submitting samples.<\/p>\n
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.<\/p>\n
