1.Scope 1.1.This specification covers the requirements for compacted, mineral-insulated, metal-sheathed cables used in assembling metal-sheathed, industrial resistance thermometers. 1.2.The materials of construction include copper, constantan, or nickel conductors, an austenitic stainless steel or nickel-chromium alloy sheath, and either magnesia (MgO) or alumina (Al2O3) insulation. 1.3.The cable diameter ranges between 3.0 mm and 9.5 mm and contains between two and eight conductors, set in various design configurations and wire spacings. 1.4.The values of temperature in this specification are based on the International Temperature Scale of 1990 (ITS-90). 1.5.The values stated in SI units are to be regarded as the standard. Values given in parentheses are for information purposes only. 1.6.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 specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Will allow the standardization of MI Cables for use in RTD sensors. Currently there is a variety of specs with no resource for customers to use in specifying this sensor component.
The title and scope are in draft form and are under development within this ASTM Committee.
