ISI Mark for Precision Roller and Bush Chains

Precision Roller and Bush Chain certifications for attachments, chains, and related sprockets guarantees adherence to Indian quality and safety criteria. IS 2403:1991 is the relevant standard, which lays out the specifications for roller chains, attachments, and sprockets applied in power transmission. Manufacturers who want BIS certification must apply via the BIS portal, send product samples for testing in BIS-approved labs, and schedule a factory inspection. BIS certifies upon compliance, therefore enabling the use of the ISI mark. Maintaining certification depends on regular audits and product testing, therefore guaranteeing constant quality and dependability in industrial uses.
