ASTM E1137

Full Name

ASTM E1137 – Standard Specification for Industrial Platinum Resistance Thermometers


This specification covers the requirements for metal-sheathed industrial platinum resistance thermometers (PRT’s) suitable for direct immersion temperature measurement. It applies to PRT’s with an average temperature coefficient of resistance between 0 and 100 °C of 0.385 %/°C and nominal resistance at 0 °C of 100 Ω or other specified value. This specification covers PRT’s suitable for all or part of the temperature range −200 to 650 °C. The resistance-temperature relationship and tolerances are specified as well as physical, performance, and testing requirements.
