Annotation of standard text ASTM E1137/E1137M-08(2020) :

This specification establishes the physical, performance, and testing requirements, as well as resistance-temperature relationship and tolerances for metal-sheathed industrial platinum resistance thermometers (PRT) suitable for direct immersion temperature measurement. All materials including the sheath materials, sensing elements, insulation, connecting wire end closure materials, epoxy materials, and connecting wires shall be in accordance with specified requirements. The PRT shall be subjected to corresponding qualification tests to demonstrate conformance to the acceptance criteria of the following properties: insulation resistance; resistance versus temperature; minimum immersion length; pressure; thermal response time; vibration; self-heating; stability; thermoelectric effect; mechanical shock; and dimensions.
