Standard Specification for Compacted Mineral-Insulated, Metal-Sheathed, Base Metal Thermocouple Cable

Abstract

This specification establishes the required material, processing and testing requirements, and also the optional supplementary testing and quality assurance and verification choices for compacted, mineral-insulated, metal-sheathed, base metal thermocouple cables with at least two thermoelements. The material of construction includes standard base metal thermoelements, austenitic stainless steel or other corrosion resistant sheath material, and either magnesia (MgO) or alumina (Al2O3) insulation. The required tests to which the thermocouple cables shall undergo for quality verification are dimensions, insulation resistance at room temperature, calibration, electrical continuity, insulation density, sheath integrity, and EMF versus temperature values.

Scope

1.1 This specification establishes requirements for compacted, mineral-insulated, metal-sheathed (MIMS), base metal thermocouple cable,2 with at least two thermoelements.3

1.2 This specification describes the required material, processing and testing requirements, optional supplementary testing, quality assurance, and verification choices.

1.3 The material of construction includes standard base metal thermoelements, austenitic stainless steel or other corrosion resistant sheath material, and either magnesia (MgO) or alumina (Al2O3) insulation.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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.
