BIS Certification for Cranked-Link Mill Chains of Welded Construction, Attachments and Sprockets, stems from IS 13927:2005, a quality, strength, and reliability standard pertaining to chains for heavy-duty industrial and mill operations. This standard encompasses design, dimensions, material, and mechanical properties for cranked-link mill chains and their attachments and sprockets. Such chains are integral to the sugar mill and cement plant industries, as well as other continuous and efficient material handling operations. IS 13927:2005 compliance certifies that the chains and sprockets endure high-load situations, defend against all types of wear, and operate seamlessly in the harshest working environments. Manufacturers of cranked-link mill chains and sprockets are to receive BIS Certification to verify that their output reliably meets national quality and safety standards. The presence of the ISI mark on these components certifies high performance, consistency in the critical dimensions, and longevity, assuring the users of their efficiency in industrial conveying and power transmission.
