ASTM E1137/E1137M-04

Historical Standard: Standard Specification for Industrial Platinum Resistance Thermometers

ASTM E1137/E1137M

Scope

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 100Ā°C of 0.385 %/Ā°C and nominal resistance at 0Ā°C of 100 Ī© or other specified value. This specification covers PRT’s suitable for all or part of the temperature range -200 to 650Ā°C. The resistance-temperature relationship and tolerances are specified as well as physical, performance, and testing requirements.

1.2 The values of temperature in this specification are based on the International Temperature Scale of 1990 (ITS-90).

1.3 The values stated in inch-pound units or SI (metric) units may be regarded separately as standard. The values stated in each system are not exact equivalents, and each system shall be independent of the other.

1.4 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.
