标准摘要
[中文适用范围]： 本国际电工标准规定了直接提供给工业过程用户的扩展电缆和补偿电缆的制造公差和识别系统（不包括矿物绝缘的扩展和补偿电缆）。这些公差是相对于IEC 60584-1中规定的热电偶电动势与温度的关系确定的。规定了用于工业过程控制的扩展电缆和补偿电缆的要求。扩展电缆和补偿电缆可以由单股（实心）导线或多股导线组成，本标准适用于此类导线。杆、扁平导线或带状的扩展和补偿导体的规格可由供应商和用户通过协议建立。 [外文原描述]： IEC 60584-3:2021 It is necessary for thermocouple temperature measurement that the electro-motive force (abbreviated as e.m.f. hereafter) of the thermocouple circuit is precisely measured by a measuring instrument. A thermocouple is electrically connected to the instrument by a proper pair of electric cables. IEC 60584-3:2021 standardizes these cables. It specifies identification and manufacturing tolerances for extension and compensating cables (mineral insulated extension and compensating cables are not included) provided directly to users of industrial processes. These tolerances are determined with respect to the e.m.f. ver-sus temperature relationship of IEC 60584-1. The requirements for extension and compensating cables for use in industrial process control are specified.
