ASTM International Standard Specification for Compacted Mineral-Insulated, Metal-Sheathed, Base Metal Thermocouple Cable ASTM E585/E585M-04

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.
