IEC 61515:2016规定了用于一般工业应用的单工、双工和三工矿物绝缘金属护套热电偶电缆和热电偶的要求。以下将使用缩写MIMS(代表“矿物绝缘金属护套”)。它涵盖热电偶电缆和仅具有T、J、E、K和N型贱金属导体的热电偶。本标准中的规范适用于交付给用户的新热电偶电缆和热电偶装置。它们在使用后不适用于产品。这第二版取消并取代了1995年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -双工和三工是标准化的。-修订绝缘电阻规格，以便用户可以选择最适合目的的产品。 -先前版本中的“表2建议的最高工作温度”被显著扩展，包括新开发的鞘管材料，并将其移至附录C。 -扩展了测试项目及其方法，并添加了指南表（表4）以方便用户。

IEC 61515:2016 establishes the requirements for simplex, duplex and triplex mineral-insulated metal-sheathed thermocouple cables and thermocouples, which are intended for use in general industrial applications. The abbreviation MIMS (for "mineral-insulated metal-sheathed") will be used hereafter. It covers thermocouple cables and thermocouples with only base-metal conductors of Types T, J, E, K and N. The specifications in this standard apply to new thermocouple cables and thermocouple units as delivered to the user. They do not apply to the product after use. This second edition cancels and replaces the first edition published in 1995. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Duplex and triplex are standardized.
- Specification of insulation resistance is revised so that the user can choose the best product to fit for the purpose.
- "Table 2 Recommended maximum operating temperatures" in the previous version is expanded significantly including newly developed sheath material and it is moved to Annex C.
- Test items and their methods are expanded and a guide table (Table 4) is added for userfriendliness.
