Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of rigid mineral insulated cables. This document is applicable to the level evaluation of rigid mineral insulated cable enterprise standards. Relevant institutions may refer to it when formulating "Leader" evaluation schemes for enterprise standards. Enterprises may also refer to it when formulating their own enterprise standards. Main technical content: 4.2 Classification of evaluation indicators 4.2.1 The evaluation indicators for the "Leader" standard of rigid mineral insulated cables are divided into basic indicators and core indicators. 4.2.2 Basic indicators include structural dimensions, insulation resistance, sheath integrity, insulation withstand voltage performance, sheath withstand voltage performance, bending withstand voltage performance, and crushing withstand voltage performance. 4.2.3 Core indicators include conductor DC resistance, sheath DC resistance, fire resistance performance under pure fire supply, fire resistance performance under fire supply combined with mechanical impact, and fire resistance performance under fire supply combined with mechanical impact and water spray. The core indicators are divided into three grades, including advanced level, which corresponds to a 5-star level in the enterprise standard ranking list; average level, which corresponds to a 4-star level in the enterprise standard ranking list; and baseline level, which corresponds to a 3-star level in the enterprise standard ranking list.
