4.2 Classification of evaluation indicators 4.2.1 The evaluation indicators of the "Leader" standard for 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 voltage resistance, jacket voltage resistance, bending voltage resistance, and flattening voltage resistance. 4.2.3 The core indicators include the DC resistance of the conductor, the DC resistance of the sheath, the fire resistance of simple fire supply, the fire resistance of fire supply plus mechanical impact, and the fire resistance of fire plus mechanical impact and water spray. The core indicators are divided into three levels, including advanced level, which is equivalent to the 5-star level in the enterprise standard ranking; average level, which is equivalent to the 4-star level in the enterprise standard ranking; and benchmark level, which is equivalent to the 3-star level in the enterprise standard ranking. star level.
