The test report has to cover every clause of IS 7142 that applies to the product, in the edition current on the date of testing. When BIS revises IS 7142 or replaces it with a new edition, existing licence holders move to the new edition by the date BIS sets in its notification.
How to get an ISI mark licence under IS 7142
The licence is granted to the manufacturer for a specific factory and product. Indian factories apply under Scheme-I; overseas factories apply under the Foreign Manufacturers Certification Scheme (FMCS) and must nominate an Authorised Indian Representative.
