BIS Certification for Explosion Proof Lighting in India

The Bureau of Indian Standards (BIS) is the national standards body of India responsible for certifying products used in hazardous areas. BIS certification is mandatory for explosion proof electrical equipment imported into or manufactured in India. AJV Tech supplies BIS certified explosion proof lighting from Raytec and Atexor, fully compliant with Indian IS/IEC standards for use in classified hazardous environments across Indian oil and gas, refinery, and petrochemical facilities.

BIS Certification for Explosion Proof Lighting in India

What is BIS Certification?

BIS (Bureau of Indian Standards) certification for explosion proof equipment is governed under the IS/IEC 60079 series of standards. These Indian standards are harmonised with the international IEC 60079 standards, ensuring that BIS certified equipment meets globally recognised safety levels. BIS certification requires products to undergo testing at BIS-approved laboratories, followed by a factory audit and ongoing surveillance. Once certified, products carry the ISI mark, which is a mandatory requirement for explosion proof equipment sold or used in India. The certification is administered through the BIS Conformity Assessment scheme and covers equipment protection types including flameproof (Ex d), increased safety (Ex e), and intrinsic safety (Ex i).

BIS vs IECEx

While BIS standards are technically harmonised with IEC standards, BIS certification is a separate national certification that cannot be substituted with IECEx certification alone. Products entering the Indian market must hold BIS certification regardless of any other international certifications they carry. However, holding IECEx certification can simplify the BIS certification process, as the technical test reports from IECEx recognised testing laboratories may be accepted by BIS as part of the application. AJV Tech works with manufacturers who hold both IECEx and BIS certifications, ensuring products are fully compliant for use in India while also being recognised internationally.

Indian Standards for Hazardous Areas

India follows the IS/IEC 60079 series for the classification of hazardous areas and the selection of equipment. IS/IEC 60079-10-1 covers the classification of areas where flammable gas or vapour hazards may exist, while IS/IEC 60079-10-2 addresses combustible dust environments. The zone classification system used in India mirrors the international IEC system: Zone 0, Zone 1, and Zone 2 for gas, and Zone 20, Zone 21, and Zone 22 for dust. Indian regulatory bodies including PESO (Petroleum and Explosives Safety Organisation) and OISD (Oil Industry Safety Directorate) mandate the use of BIS certified equipment in all classified hazardous areas within oil refineries, gas processing plants, petrochemical facilities, and offshore installations.
