BIS Certification for Electric Immersion Water Heaters

BIS Certification for Electric Immersion Water Heaters (IS 302 Part 2 / Sec 201):2008

BIS Certification for Electric Immersion Water Heaters | IS 302-2-201:2008

Introduction

Electric immersion water heaters are widely used in Indian households for quick and portable water heating. Since these appliances operate directly in water and are connected to electricity, they pose potential risks such as electric shock, overheating, and short circuits. To ensure consumer safety and product reliability, the Bureau of Indian Standards (BIS) has made certification mandatory under IS 302 Part 2 Section 201:2008.

This blog explains the BIS Certification requirements for Electric Immersion Water Heaters, including the applicable standard, safety requirements, testing process, and approval procedure in India.

What Is BIS Certification for Electric Immersion Water Heaters?

BIS Certification is a conformity assessment scheme issued by the Bureau of Indian Standards, confirming that a product complies with prescribed Indian safety standards.

For electric immersion water heaters, compliance with IS 302-2-201:2008 is mandatory. Once approved, manufacturers can affix the ISI Mark, signifying that the product meets national electrical safety and quality norms.
