BIS Certificate for Electrolysers – Complete Guide
Electrolysers are electrical devices that split water into hydrogen and oxygen using electrolysis. Because they involve high electrical currents, power electronics, and pressurized gases, they must meet strict electrical safety requirements. A valid BIS Licence for Electrolysers under IS 302 (Part 1):2024 confirms compliance with Indian electrical safety standards before these systems can be legally manufactured, imported, or sold in India.
Electrolyser technology is becoming one of the most important components of the global clean energy transition. Electrolysers are systems that use electricity to split water into hydrogen and oxygen through the electrolysis process. Hydrogen produced through electrolysis—often referred to as green hydrogen when renewable energy is used—is increasingly being adopted across industries such as energy, transportation, chemicals, steel production, and power storage.
India has also announced strong policy initiatives for hydrogen production under the National Green Hydrogen Mission, which has significantly increased demand for electrolyser technologies. These systems are used in industrial hydrogen generation plants, laboratory hydrogen generators, energy storage applications, and hydrogen fueling infrastructure.
Because electrolysers operate with high electrical loads, electrolytic cells, conductive electrolytes, control systems, and power electronics, improper design can create serious safety hazards. Electrical faults may cause overheating, insulation failure, electrical shocks, or fire hazards. Therefore, regulatory safety standards are essential to ensure these systems are safe for operation.
To regulate the safety of electrical appliances and equipment, India requires compliance with the national standards established by the Bureau of Indian Standards. Manufacturers and importers must obtain a BIS Certificate for Electrolysers under IS 302 (Part 1):2024, which covers the safety of household and similar electrical appliances.
Obtaining a BIS Certification for Electrolysers confirms that the product has undergone safety testing, electrical evaluation, and factory verification to ensure compliance with Indian standards. A valid BIS License for Electrolysers also allows the manufacturer to use the ISI certification mark, indicating that the product meets recognized safety benchmarks.
This comprehensive guide explains everything manufacturers, importers, technology startups, and industrial equipment suppliers need to know about obtaining a BIS Licence for Electrolysers in India. It covers certification requirements, application procedures, testing standards, compliance obligations, documentation requirements, certification costs, and regulatory penalties.
What is BIS Certification?
BIS Certification is the official product conformity assessment scheme administered by the Bureau of Indian Standards (BIS). The primary objective of this certification system is to ensure that products sold in India meet defined standards for safety, performance, and quality. Electrical equipment, including electrolysers, must comply with applicable Indian standards before entering the market.
