ASTM E1159-98
Historical Standard: ASTM E1159-98 Standard Specification for Thermocouple Materials, Platinum-Rhodium Alloys, and Platinum
SUPERSEDED (see Active link, below)
ASTM E1159
1. Scope
1.1 This specification covers non-insulated platinum-rhodium alloys (weight percent composition), and platinum thermocouple wires that meet the requirement of Specification E 230 and NBS Monograph 175.
1.2 This specification does not cover platinum and platinum rhodium materials, which require a higher purity than specified in 5.1, such as used for temperature coefficient of resistance (TCR) measurements or standards type calibration. For requirements of this superior quality, it is suggested that suppliers of precious metals be contacted.
