BIS CRS Certification for Microwave Ovens (IS 302-2-25:2014)

Complete Guide to BIS CRS Certification for Microwave Oven Manufacturers and Importers in India

Microwave ovens have become an essential kitchen appliance in homes, restaurants, hotels, offices, and commercial establishments. They provide quick cooking, reheating, grilling, and defrosting functions, making food preparation more convenient. Since microwave ovens are electrical appliances that operate at high voltage and generate electromagnetic energy, ensuring their safety is critical.

To protect consumers and maintain product quality, the Bureau of Indian Standards (BIS) has included microwave ovens under the Compulsory Registration Scheme (CRS). Manufacturers and importers intending to sell microwave ovens in India must obtain BIS CRS Certification and comply with IS 302 (Part 2/Sec 25):2014, which specifies the safety requirements for microwave ovens, including combination microwave ovens.

What is BIS CRS Certification?

The BIS Compulsory Registration Scheme (CRS) is a mandatory product registration program administered by the Bureau of Indian Standards (BIS) under the Electronics and Information Technology Goods (Requirement for Compulsory Registration) Order.

Under this scheme, manufacturers must have their products tested in a BIS-recognized laboratory and obtain BIS registration before manufacturing, importing, distributing, or selling covered products in India. Once registered, the product can bear the Standard Mark along with the applicable BIS Registration Number.
