BIS Certification for Freezers under IS 7872:2020 is important to make sure that deep freezers sold in India are safe, reliable, and of good quality. Deep freezers are used in homes, supermarkets, hotels, restaurants, hospitals, laboratories, and other commercial places to store frozen food and other temperature-sensitive products. Therefore, they must work safely, provide proper cooling, and use electricity efficiently.
The IS 7872:2020 standard lays down the requirements for the design, safety, performance, testing, and energy efficiency of deep freezers. Under the applicable BIS Quality Control Order (QCO), manufacturers and importers must obtain BIS Certification before they can manufacture, import, or sell deep freezers in India. Once certified, they can use the ISI Mark on their products, showing that the deep freezer meets Indian quality and safety standards and helping customers trust the product.
What Is BIS Certification for Freezers?
The Bureau of Indian Standards (BIS) is India's national authority responsible for developing and enforcing product quality and safety standards. BIS for Freezers confirms that the product complies with the applicable Indian Standard, ensuring it meets the required safety, quality, and performance requirements before being sold in the Indian market.
Manufacturers who obtain ISI Certification for Freezers are authorized to display the ISI mark on their products. This mark assures consumers, distributors, and regulatory authorities that the freezer has undergone the required testing and factory inspection as per BIS guidelines. A valid BIS License for Freezers demonstrates that the product fully complies with Indian regulatory requirements and is approved for manufacture, import, and sale in India.
Why BIS Certification Matters for Freezers
- Safety and Consumer Protection - Freezers operate continuously using electricity, making electrical insulation, compressor safety, and temperature control essential. BIS-certified products are tested to ensure safe operation and reduce the risk of electrical shocks, overheating, and fire hazards.
- Consistent Performance and Quality - Certified freezers are evaluated for cooling efficiency, temperature stability, energy performance, and durability. BIS Certification for Freezers ensures that products provide reliable cooling and long-lasting performance.
- Compliance with the Applicable Indian Standard - The applicable Indian Standard for freezers sets clear requirements for construction quality, electrical safety, performance, and marking. Certification confirms that the product complies with these uniform standards.
- Market Trust and Brand Credibility - Products carrying the ISI mark inspire confidence among buyers, retailers, and institutional purchasers. BIS certification gives manufacturers a clear competitive advantage.
- Legal Compliance under BIS QCO - The BIS QCO for Freezers makes certification mandatory for applicable products. Non-certified products are prohibited from being manufactured, sold, or imported in India.
BIS Testing & Quality Standards for Deep Freezers
To ensure safe usage, reliable cooling performance, and long service life, deep freezers
are tested under IS 7872:2020 by the Bureau of Indian Standards (BIS). These testing
and inspection requirements are followed during manufacturing to confirm that every
unit meets essential safety and quality expectations before it is sold in the Indian
market.

- Component inspection (S): Ensures proper quality of fitted parts and assembly.
- Design and build verification (S): Confirms safe construction standards.
Safety, Stability & Environmental Resistance
- Stability check (S): Ensures appliance does not tip or become unstable.
- Moisture resistance test (S): Checks protection against humidity exposure.
- Heat and fire resistance test (S): Ensures safe performance under thermal
stress.
- Corrosion resistance test (S): Confirms durability against rust and
environmental damage.
- Clearance and insulation spacing check (S): Ensures safe internal electrical
separation.
BIS Registration Process for Freezers
Obtaining BIS Registration for Freezers involves a systematic process to ensure that the product meets the applicable Indian Standard and all regulatory requirements. The general process includes the following steps -
- Online Registration - Manufacturers register on the BIS Manak Online Portal by submitting company details, factory information, and freezer product specifications. Foreign manufacturers must appoint an Authorized Indian Representative (AIR) in India.
- Product Testing - Freezer samples are tested at BIS-approved laboratories to verify compliance with the applicable Indian Standard. The tests evaluate electrical safety, cooling performance, insulation, temperature stability, energy efficiency, durability, and other prescribed safety and performance requirements before BIS certification is granted.
- Application Submission - Manufacturers submit the BIS application along with test reports, technical documents, product specifications, quality control procedures, and factory information. Foreign manufacturers must also provide AIR authorization documents.
- Factory Inspection - BIS officials inspect the manufacturing facility to verify production processes, quality control systems, testing facilities, raw material quality, and compliance with BIS requirements.
- Grant of BIS License -Upon successful evaluation of the application, product testing, and factory inspection, BIS grants the licence under the applicable certification scheme, authorizing the manufacturer to produce and sell certified freezers in the Indian market.
- Use of ISI Mark - After receiving the BIS licence, manufacturers are authorized to affix the ISI Mark along with the CM/L number on the freezer, confirming compliance with the applicable Indian safety and quality standards.
