Deep freezers are essential electrical appliances used in homes, restaurants,
supermarkets, and food storage units for preserving food, medicines, and other
temperature-sensitive items for a longer time. They work by maintaining consistently low
temperatures, which help in keeping products fresh, safe, and usable for extended
periods.
Since freezers run continuously and depend on electrical systems and cooling
components, safety and performance are very important. To ensure reliable operation
and protection against electrical hazards, temperature failure, leakage issues, and
mechanical faults, the Bureau of Indian Standards has defined requirements under IS
7872:2020. BIS certification for freezers confirms that the product meets the required
Indian safety and quality standards for safe use in the Indian market.
Overview of IS 7872:2020 Standard
This is the Indian Standard that defines safety, performance, and construction
requirements for household and commercial freezers. It is issued by the Bureau of
Indian Standards (BIS) to ensure that freezers used for storage and preservation
operate safely, efficiently, and reliably under normal working conditions.
This standard ensures that the product is:
- Safe from electrical shock and insulation failure risks.
- Protected against temperature control failures and cooling system faults.
- Designed with durable materials suitable for continuous operation.
- Tested for proper cooling performance, efficiency, and stability.
- Built to operate safely under varying environmental and load conditions.
- Marked with correct ratings, usage details, and safety instructions
Who Requires BIS Certification for deep freezers?
BIS Certification is required for businesses involved in the manufacturing, importing,
and distribution of freezers in India.
It applies to:
- Manufacturers – Must obtain BIS certification before producing and selling
freezers in the Indian market.
- Importers – Need to ensure that imported freezers comply with BIS
requirements before sale in India.
- Suppliers/Distributors – Should deal only in BIS-certified freezers to ensure
compliance and market acceptance.
This certification is regulated by the Bureau of Indian Standards (BIS).
Benefit: BIS certification ensures product safety, reliable cooling performance, legal
compliance, and builds strong customer trust in the product.
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

- 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.
How to get bis license for frozen storage units

To obtain a BIS license, manufacturers must follow the certification process prescribed by the Bureau of Indian Standards under IS 302 (Part 2/Sec 23). This process confirms that the product meets required safety and quality standards for sale in India.
- Online Registration: Apply through the BIS Manak Online Portal by submitting company details, factory information, and product specifications. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Product Testing: Samples are tested in BIS-approved laboratories to check electrical safety, insulation strength, temperature rise, leakage current, mechanical durability, and overall operational safety of skin and hair care appliances.
- Application Submission: Submit the BIS application along with test reports, technical documents, manufacturing details, and quality control information. Foreign applicants must also submit AIR documents.
- Factory Inspection: BIS officials inspect the manufacturing unit to verify production capability, testing facilities, quality systems, and compliance with applicable standards.
- Grant of BIS License:If the product and factory meet all BIS requirements, the license is issued under Scheme-I.
- Use of ISI Mark : After approval, the manufacturer can use the ISI Mark with the CM/L number, confirming compliance with BIS standards.
