Under IS 13252, the BIS CRS (Compulsory Registration Scheme) accreditation for power adapters used in IT equipment guarantees conformity with Indian safety and quality criteria. Manufacturers selling in India have this accreditation required of them. Product testing in BIS-approved laboratories, application submission, and BIS approval comprise the procedure. Authorized Indian Representatives (AIR) are required of foreign manufacturers. Important records include test results, ISO 9001 certifications, and business licenses. Products once certified have to show the BIS CRS mark. This guarantees for power adapters in India's IT industry safety, dependability, and regulatory compliance.
