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 can refer to it when formulating "Leader" evaluation schemes for enterprise standards. Enterprises can 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 rigid mineral insulated cable "Leader" standards 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 exposure, fire resistance performance under fire exposure combined with mechanical impact, and fire resistance performance under fire exposure combined with water spray. Core indicators are divided into three grades, including advanced level, equivalent to a 5-star level in the enterprise standard ranking; average level, equivalent to a 4-star level in the enterprise standard ranking; and baseline level, equivalent to a 3-star level in the enterprise standard ranking.
