A BIS certification-approved license for butterfly valves ensures compliance with Indian standards for quality, safety, and performance. Manufacturers must follow IS 13095:2020 (or applicable standards) and obtain certification through the Bureau of Indian Standards (BIS). The process includes product testing in BIS-approved labs, application submission, factory inspection, and compliance verification. Upon approval, the manufacturer receives a BIS license, allowing them to use the ISI mark on butterfly valves. This certification is mandatory for regulated products and enhances credibility in the market. Regular audits and renewals are required to maintain compliance and ensure product reliability.
