1.1本规范规定了E、J、K、N和T型双联热电偶导线的要求，用E玻璃、S玻璃、非晶硅纤维或多晶纤维绝缘。 1.2以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1本规范提出了浸渍和非浸渍的要求- 通常接受的工业用浸渍纤维绝缘热电偶导线，但不试图定义此类用途。 4.2补充文件包含对暴露在高湿度下的绝缘热电偶导线的要求。采购订单或询价单应说明是否需要本补充文件。

1.1 This specification sets forth the requirements for duplex, types E, J, K, N and T thermocouple wire, insulated with E-glass, S-glass, amorphous silica fiber or polycrystalline fiber. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 4.1 This specification presents the requirements for impregnated and non-impregnated fiber insulated thermocouple wire for normally accepted industrial use, but does not attempt to define such usage. 4.2 A supplement contains the requirements for insulated thermocouple wire that will be exposed to high humidity. The purchase order or inquiry shall specify if this supplement is required.
