矿物绝缘金属护套热电偶电缆和热电偶

[中文适用范围]： 本国际标准规定了用于一般工业应用的单芯、双芯和三芯矿物绝缘金属护套热电偶电缆和热电偶的要求。下文中将使用缩写 MIMS（“矿物绝缘金属护套”）。它涵盖了仅具有 T、J、E、K 和 N 型贱金属导体的热电偶电缆和热电偶。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单元。它们不适用于使用后的产品。外部密封件、终端、连接件和其他附件不属于本国际标准的范围。本标准不适用于贵金属热电偶电缆和热电偶。其他标准涉及核主回路应用的特殊要求。 [外文原描述]： 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.
