Standard Specification for Magnesium Oxide and Aluminum Oxide Powder and Crushable Insulators Used in the Manufacture of Metal-Sheathed Platinum Resistance Thermometers, Base Metal Thermocouples, and Noble Metal Thermocouples
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the requirements for magnesium oxide (MgO) and aluminum oxide (Al2O3) powders and crushable insulators used to manufacture metal-sheathed platinum resistance thermometers (PRTs), noble metal thermocouples, base metal thermocouples, and their respective cables. The following test shall be performed to meet the requirements specified: breaking force test; wet chemical analysis; fusion calorimetric analysis; quantitative analysis; and density determination.
Scope
1.1 This specification covers the requirements for magnesium oxide (MgO) and aluminum oxide (Al2O3) powders and crushable insulators used to manufacture metal-sheathed platinum resistance thermometers (PRTs), noble metal thermocouples, base metal thermocouples, and their respective cables.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
