Scope: This standard specifies the product classification, technical requirements, test methods, inspection rules, marking, packaging, etc. of compensating wires for thermocouples. This standard is applicable to the compensation wires (hereinafter referred to as compensation wires) used with thermocouples with graduation numbers S, R, K, N, E, J and T. The insulating layer and sheath of the compensation wire are mainly made of polyvinyl chloride, alkali-free glass fiber and polytetrafluoroethylene. For other materials, if they can meet the technical requirements of this standard, they can also be used.
