Hinged BIS (Bureau of Indian Standards) certification guarantees adherence to Indian quality and safety norms. Standards such IS 205:1992 (Ferrous Metal Butt Hinges) and IS 1341:1992 (Steel Butt Hinges) certify hinges. Manufacturers have to apply via the BIS Manak Online Portal, turn in necessary documentation, and go through lab testing and manufacturing inspections. Approved, they get an ISI mark signifying product quality. The certification has to be renewed often and lasts one to two years. BIS certification guarantees conformance to Indian Standard (IS) standards, necessary for market acceptance and regulatory compliance, hence improving product dependability.
