BIS Certification for Deep Freezers in India – Complete ISI Mark Process (IS 7872:2020)

Introduction

Deep freezers are essential refrigeration appliances widely used in homes, supermarkets, restaurants, pharmaceutical companies, cold storage facilities, hotels, and food processing industries. These appliances are designed to preserve frozen food products and temperature-sensitive materials for extended periods.

In India, the quality, safety, energy efficiency, and performance standards for deep freezers are regulated under the Bureau of Indian Standards (BIS). Manufacturers and importers must comply with the applicable Indian Standard before marketing their products in the Indian market.

The applicable standard for deep freezers is IS 7872:2020. Products certified under BIS are permitted to use the ISI Mark, which indicates compliance with Indian quality and safety standards.

This complete guide explains the BIS Certification process for Deep Freezers in India, including eligibility, testing requirements, documentation, factory inspection, benefits, and compliance procedures.

What is BIS Certification?

BIS Certification is a conformity assessment scheme operated by the Bureau of Indian Standards (BIS), the national standards authority of India. Products approved under the scheme are allowed to carry the ISI Mark.

The ISI Mark assures consumers that the product has been tested and verified according to Indian Standards for safety, reliability, and quality.
