Introduction
Last winter, a few room heaters available on the market experienced minor incidents of overheating which sparked safety concerns amongst consumers purchasing these heaters. Many manufacturers learned that their products did not fully comply with Indian Safety Standards. This is the significance of BIS Certification for Safety of household and similar electrical appliances-Room heaters IS 302 (Part 2/Sec 30), as it indicates that the heaters are compliant with electrical, thermal and mechanical safety requirements. Compliance protects the user and promotes warranty endorsement which is essential in a competitive market. Moreover, for manufacturers and importers, the BIS certification signifies a legal requirement and an assurance to the consumer.
What is BIS Certification for Room heaters IS 302 (Part 2/Sec 30)

The Bureau of Indian Standards (BIS), which is India’s National Standards Body responsible for assessing quality and safety standards, issues BIS certification. IS 302 (Part 2/Sec 30) specifies the standard that applies for room heaters and the safety standards established in respect of electric appliances for household or equivalent purposes.
By obtaining the BIS Certificate, the consumer has confirmed that the room heater meets or exceeds BIS standards for;
- Electrical Safety – Protection against shock and shorting-of-circuit
- Thermal Safety – Protection against over-heating and fires
- Mechanical Safety – Protection against structure integrity and handling safety
Every room heater that is sold or distributed in India must conform to this standard. Once BIS Certification has been granted, the manufacturer is then able to display the ISI mark, an indication to the consumer of quality and safety they rely on.

What is IS 302 (Part 2/Sec 30)?
IS 302 (Part 2/Sec 30) is the Indian Standard set by the Bureau of Indian Standards (BIS) for the safety of household and similar electrical appliances, specifically for room heaters.ISI MARK
Key features of the standard consist of:
- Electrical Safety: Protection against electric shock and electric short circuit.
- Thermal Safety: Maximum temperature rise for thermal safety to limit the risk of over-heating or fire.
- Mechanical Safety: The integrity, stability and durability of the structural components of the appliance.
- Labeling and Instructions: Providing appropriate labels with voltage ratings (the label must clearly identify the source of voltage), safety information and instructions for the consumer.
To sell any room heater in India means to comply with IS 302 (Part 2/Sec 30) as it is mandatory for BIS certification and the ISI mark guaranteeing the user a safe and robust product.
Why BIS Certification Mandatory for Room heaters
BIS certification is not merely a suggestion, it is a legal requirement for any electrical appliances that are used in people’s homes (which includes electric room heaters) in India. The main reasons are :
- Consumer safety: Room heaters employ both power and heat, and if room heaters are non-compliant with safety standards, they may potentially do things such as shock, cause burns to users or even cause fires.
- Compliance: The certification puts the BIS mark on the heater after they have passed the IS 302 (Part 2/Sec 30) measured against the Indian standard (minimum) safety standards.
- Market access: Without being BIS certified, manufacturers cannot legally sell room heaters, or import/distribute room heaters in India.
- Brand trust: The room heater with ISI mark is reliant and safe adding trust to consumers.
- Liability protection: Being compliant decreases the chance of recalls from the government, legal action and harm to the company.
Key features of BIS Certification
BIS Certification for room heaters under IS 302 (Part 2/Sec 30) ensures that products comply with strict safety and quality requirements. The main aspects of BIS Certification are:
- ISI Mark: Authorized use of the ISI mark demonstrates the safety and reliability of the product to consumers.
- Electrical Safety Assessment: Electrical safety standards assess protection against shock, short circuits and electrical safety hazards to consumers.
- Formation of Thermal Safety Standards: Temperature standards for room heaters limit overheating and prevent fire hazards.
- Mechanical Safety Criteria: Mechanical safety clauses ensure appropriate construction and quality materials product, provide structural integrity, then define durability and safe handling.
- Mandatory Testing & Inspection: Each product undergoes extensive laboratory testing of the product prior to certification and factory audits of compliance by the BIS.
- Periodic Surveillance: The BIS conducts periodic surveillance of manufacturers to ensure continued compliance to the standard.
- Consumer Confidence & Access to Market: Certification is legally required to sell room heaters in India, whilst promoting additional confidence in the marketplace.

Step-by-Step Process of BIS Certification for Room heaters
Step1: Application
- The Manufacturer or importer submits an application with the BIS, outlining the product, product specifications, product technical specifications, and test reports (if they are available based on the product being tested).
- The application must be thoroughly and completely completed in order to ensure acceptance, and that the application can be processed efficiently.
Step2: Testing
- The product will be inspected by state authorized laboratories
- Testing includes:
- designated by the BIS to see if the samples passed based on the technical specifications of the product in relation to.
- electrical insulation/shock hazards; temperature rise/overheating characteristics.
- mechanical safety and stability of the product.
- short circuit/safety related to components used on the product.
Step3: Factory Inspection
Once testing is completed and results are successfully determined from the BIS or their authorized laboratories, an inspection will be conducted by a BIS representative of the Manufacturer on-site to see and observe:
- quality of the Manufacturer’s processes; quality control of the Manufacturer’s processes; confirmed the technical specifications given
- determined company processes that would allow the Manufacturer to scale production to manufacture room heaters that meet technical specifications
Step4: Grant of License
- License Issuance Once both the testing and factory inspection was successful, that begins the process of being issued a license to apply the ISI mark.
- The manufacturer can now legally sell or distribute the room heater in India with BIS certification.
Step5: Periodic Surveillance
- BIS periodically checks certified products to ensure ongoing compliance.
- This includes random sample testing and factory inspections, maintaining product safety standards over time.
