ASTM E608 Standard Specification for Mineral-Insulated, Metal-Sheathed Base Metal Thermocouples
ASTM E608 矿物绝缘,金属铠装基底金属热电偶的标准规范

This specification covers the requirements for mineral-insulated, metal-sheathed base metal thermocouples for industrial or high-reliability applications. Provisions are made herein for selecting thermoelements, and insulation and sheath materials, and measuring junction configuration, thermocouple assembly length, and the type of transition or termination. This specification also includes provisions for quality assurance or verification program requirements, or both, as the purchaser's option.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
 
1. Scope
1.1 This specification covers the requirements for mineral-insulated, metal-sheathed base metal thermocouples for industrial or high-reliability applications. It applies specifically to thermocouples fabricated from sheathed thermocouple material in accordance with Specification E 585/E 585M. Provisions are made for selecting thermoelements, insulation, and sheath material, and measuring junction configuration, thermocouple assembly length, and the type of transition or termination.
1.2 This specification also includes provisions for quality assurance or verification program requirements, or both, as a purchaser's option.
1.3 The values stated in SI (metric) units or inch-pound units may be regarded separately as the standard. The values stated in each system are not the exact equivalents, and each system shall be used independently of the other.
This standard does not purport to address all of the safety concerns, 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.
