1.1 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&#176C of 0.385%/&#176C and nominal resistance at 0&#176C of 100 [omega] or other specified value. This specification covers PRT's suitable for all or part of the temperature range -200 to 650&#176C. The resistance-temperature relationship and tolerances are specified as well as physical, performance, and testing requirements.</p> <p>1.2 The values of temperature in this specification are based on the International Temperature Scale of 1990 (ITS-90)<b> </b>. </p>
