This harmonized standard has been jointly revised on November 25, 2024. For this purpose, CSA Group and ULSE are issuing revision pages dated November 25, 2024, and ANCE is issuing a new edition dated November 25, 2024. This harmonized standard was prepared by the Association of Standardization and Certification, (ANCE), CSA Group, and ULSE. The efforts and support of the Technical Harmonization Subcommittee, 32B, Fuses, Fuseholders, on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the Standard. The present Mexican standard was developed by the CT 32 “Fusibles” from the Comite de Normalizacion de la Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaboration of the manufacturers and users of fuseholders. This standard was reviewed by the CSA Subcommittee on Fuses and Fuseholders, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
