Amendment 1 - Mineral insulated cables with a rated voltage not exceeding 750 V. Part 1: Cables

This technical document serves as an amendment to an international specification concerning mineral-insulated cables with a rated voltage up to 750 volts. Published by the International Electrotechnical Commission, this addendum updates the original requirements established in 1988. The primary focus of this document is to modify specific clauses within the foundational standard regarding cable construction and performance criteria. It addresses necessary technical adjustments to ensure the continued safety and reliability of electrical installations utilizing these particular cable types. The content details revised testing procedures, material specifications, and dimensional tolerances that complement the base document. By introducing these changes, the document aims to align current manufacturing practices with updated industry needs and safety observations. It is intended for use by manufacturers, testing laboratories, and regulatory bodies involved in the production and certification of low-voltage mineral-insulated cables. The modifications cover critical aspects that impact the mechanical strength and electrical insulation properties of the cables, ensuring they meet modern operational demands without altering the fundamental design philosophy of the original standard.
