Warming plates and similar appliances are electrical devices used to keep food warm for longer periods without overcooking it. They are commonly used in homes, hotels, restaurants, and catering services to maintain food temperature before serving. These appliances are easy to use and help improve convenience in both household and commercial kitchens.
Since these products operate on electricity and involve heat, safety becomes very important. To ensure safe usage, the Bureau of Indian Standards (BIS) has defined requirements under IS 302 (Part 1):2024. This standard focuses on electrical safety, construction, and performance of such appliances. BIS certification ensures that warming plates and similar appliances are properly tested and meet required safety standards before being sold in the Indian market, helping ensure reliable and safe use.
Who Needs BIS Certification for Warming Plates & Similar Appliances
BIS certification under IS 302 (Part 1):2024 is required for businesses involved in manufacturing, importing, or selling these electrical appliances in India, especially when covered under a Quality Control Order (QCO).
