Anotácia textu normy ASTM E2181/E2181M-19 :
This specification establishes the requirements for materials and manufacturing, dimensions, inspection and testing, and processing of compacted, mineral-insulated, metal-sheathed Type S (platinum-10 % rhodium versus platinum), Type R (platinum-13 % rhodium versus platinum), and Type B (platinum-30 % rhodium versus platinum-6 % rhodium) noble metal thermocouples, and thermocouple cables with at least one noble metal thermoelement pair. This specification describes both the required processing and testing requirements, and also the optional supplementary testing and quality assurance requirements. Additionally, provisions are made herein for selecting the type of noble metal thermocouple or thermoelements, either magnesia (MgO) or alumina (Al2O3) insulation, and a noble metal alloy or other alternate heat-resistant sheath material. Provisions are also made for selecting a thermocouple measuring junction style and for a transition or termination.

1.1 This specification establishes dimensional and material requirements for compacted, mineral-insulated, metal-sheathed (MIMS), Type S (platinum-10 % rhodium versus platinum), Type R (platinum-13 % rhodium versus platinum), and Type B (platinum-30 % rhodium versus platinum-6 % rhodium) noble metal thermocouples. This specification also establishes dimensional recommendations and material requirements for compacted MIMS cable with at least one noble metal thermoelement pair. 1.2 This specification describes both the required processing and testing requirements and also the optional supplementary testing and quality assurance requirements. 1.3 Provisions are made for selecting the type of noble metal thermocouple or thermoelements, either magnesia (MgO) or alumina (Al2O3) insulation, and a noble metal alloy or another heat-resistant sheath material. Provisions are also made for selecting a thermocouple-measuring junction style and for a transition or termination. 1.4 The values stated in inch-pound units or SI (metric) units may be regarded separately as standard. The values stated in each system are not the exact equivalents, and each system shall be used independently of the other. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
