Specifying accuracy and quality standards for length-measuring tools including gauges, rulers, and tapes, the BIS Certification License for Material Measure of Length guarantees compliance with IS 6787:1973. Manufacturers who want BIS certification must apply via the Manakonline Portal, submit an application (Form V), send test findings from BIS-registered labs, and go through a factory inspection. The process covers payment of certification fees, compliance verification, and quality assurance. Approved, the manufacturer gets a BIS permission to apply the ISI mark, therefore guaranteeing product dependability. Continual certification calls for regular audits and license renewals. In India's measuring and calibrating sector, this accreditation improves consumer confidence, regulatory compliance, and marketability.
