BIS Certification Consultancy for Thermal Storage Room Heaters – IS 302 (Part 1):2024 | IEC 60335-1:2020

Introduction: BIS Certification for Thermal Storage Room Heaters

Thermal Storage Room Heaters are electrical heating appliances designed to store thermal energy and release heat into a room or surrounding area. Because these appliances involve electrical heating elements, high operating temperatures and thermal energy storage, safety and performance requirements are important considerations for manufacturers and businesses supplying these products in India.

The Bureau of Indian Standards (BIS) has identified Thermal Storage Room Heaters within the product-wise testing scope associated with IS 302 (Part 1):2024 | IEC 60335-1:2020. BIS Laboratory Information Management System (LIMS) also provides a specific testing entry for Thermal Storage Room Heaters under IS 302: Part 1, confirming that the product category is covered within the relevant laboratory testing framework.

The revised IS 302 (Part 1):2024 corresponds to IEC 60335-1:2020 and establishes general safety requirements for applicable household and similar electrical appliances. BIS lists the standard under the safety framework for electrical appliances.

For businesses preparing for mandatory compliance, it is important to identify the correct product category, applicable Indian Standard, certification route, testing requirements and latest Quality Control Order provisions before placing applicable products in the Indian market.

This complete guide explains the BIS Certification Consultancy requirements for Thermal Storage Room Heaters, including applicable standards, BIS testing, required documents, certification process, factory inspection, cost factors, timelines, common rejection reasons, FAQs and compliance requirements.


About Thermal Storage Room Heaters

Thermal Storage Room Heaters are electrical appliances designed to generate and store heat before gradually releasing that stored thermal energy into the surrounding environment.

Unlike conventional room heaters that may continuously generate heat while operating, thermal storage heating appliances generally use a thermal storage medium or material that retains heat and releases it over a period of time.

Depending on the product design, these appliances may incorporate:

  • Electrical heating elements
  • Thermal storage materials
  • Insulation systems
  • Temperature control mechanisms
  • Thermostats
  • Safety cut-outs
  • Electrical control components
  • Protective enclosures
  • Ventilation or heat-release arrangements

Since these appliances combine electrical systems with thermal energy storage, their design must address safety considerations such as protection against electric shock, excessive temperature, overheating, abnormal operation, insulation failure and fire-related hazards.

The exact BIS applicability should always be determined based on the actual construction, intended use, electrical rating and regulatory classification of the product.


What is BIS Certification for Thermal Storage Room Heaters?

BIS Certification is a conformity assessment process administered by the Bureau of Indian Standards (BIS).

Where a product is covered by a mandatory Quality Control Order, manufacturers are required to demonstrate conformity with the applicable Indian Standard and obtain the required BIS licence before manufacturing, importing or selling the covered product in India, subject to the applicable regulatory provisions.

For the relevant general safety framework, the applicable standard is:

IS 302 (Part 1):2024

Corresponding international standard:

IEC 60335-1:2020

The standard is titled:

Household and Similar Electrical Appliances – Safety – Part 1: General Requirements

BIS identifies IS 302 (Part 1):2024 as the seventh revision of the general safety standard and lists it under the electrical appliances and accessories category.

BIS certification under the applicable Scheme-I / ISI Mark framework is intended to demonstrate that products conform to the relevant requirements and that the manufacturer has the capability to maintain consistent product quality.


Applicable Standard: IS 302 (Part 1):2024 | IEC 60335-1:2020

The relevant standard is:

IS 302 (Part 1):2024

IEC 60335-1:2020

Title: Household and Similar Electrical Appliances – Safety – Part 1: General Requirements

The revised Indian Standard is identified by BIS as being identical under dual numbering with IEC 60335-1:2020.

Depending on the specific product and applicable requirements, safety evaluation may cover areas such as:

  • Classification
  • Marking and instructions
  • Protection against access to live parts
  • Power input
  • Current input
  • Heating
  • Temperature rise
  • Leakage current
  • Electric strength
  • Moisture resistance
  • Abnormal operation
  • Mechanical strength
  • Construction

The actual testing requirements must be determined based on the product's construction and applicable test clauses.


Factory Inspection Process

Where applicable under the BIS certification procedure, factory inspection is conducted to evaluate whether the manufacturer can consistently produce products conforming to the relevant Indian Standard.

The assessment may include:

  • Manufacturing infrastructure
  • Production process
  • Raw material control
  • Incoming inspection
  • In-process inspection
  • Final inspection
  • Testing facilities
  • Calibration system
  • Quality control records
  • Trained technical personnel
  • Product sampling

Before inspection, manufacturers should ensure that:

  • Production facilities are operational
  • Required testing equipment is available
  • Calibration certificates are valid
  • Quality control procedures are documented
  • Testing personnel are available
  • Production records are maintained
  • Inspection records are properly documented

Common Reasons for BIS Certification Delay or Rejection

Incorrect Product Classification

Incorrect product classification may result in the wrong certification route or standard being selected.

Wrong Standard Selection

The product must be correctly mapped to the applicable Indian Standard.

Incomplete Documentation

Missing documents can result in queries and processing delays.

Laboratory Test Failure

Failure during testing may require corrective action and re-testing.

Inconsistent Model Numbers

Model numbers must be consistent across applications, test reports, technical documents and product marking.

Incorrect Product Marking

Improper marking can lead to compliance issues.

Poor Quality Control

Manufacturers must maintain appropriate quality control systems.

Factory Readiness Issues

Where factory inspection applies, the manufacturing facility should be properly prepared.

Brand Authorization Problems

Brand ownership and authorization should be clearly documented.

Delayed Response to BIS Queries

Failure to respond promptly to BIS queries can extend the certification timeline.


BIS Certification Cost Factors

The total cost may depend on:

  • BIS government fees
  • Application fees
  • Laboratory testing charges
  • Number of product models
  • Product complexity
  • Number of samples
  • Factory location
  • Inspection expenses
  • Testing equipment requirements
  • Documentation requirements
  • Consultancy charges
  • Foreign manufacturer requirements

BIS LIMS data shows different testing charges for Thermal Storage Room Heaters across laboratory listings. One listing shows ₹30,000 excluding taxes, while a product-wise testing document lists ₹45,000 for the category at another laboratory. Therefore, manufacturers should obtain a product-specific testing quotation before budgeting for certification.

The total BIS certification cost should not be assumed from laboratory testing charges alone.


BIS Certification Timeline

The overall timeline depends on:

  • Product complexity
  • Laboratory availability
  • Testing results
  • Documentation readiness
  • Factory readiness
  • Inspection scheduling
  • BIS queries
  • Corrective actions
  • Re-testing requirements

Manufacturers should start the certification preparation process well before the applicable implementation date.

Early preparation allows sufficient time for:

Product Assessment → Standard Identification → Testing → Corrective Action → Documentation → Application → Inspection → Approval
