(Specification)Standard Specification for Thermocouple Materials, Platinum-Rhodium Alloys, and Platinum
Standard Specification for Thermocouple Materials, Platinum-Rhodium Alloys, and Platinum
ABSTRACT
This specification covers non-insulated platinum rhodium alloys (weight percent composition), and platinum thermo elements. The purity of platinum for use in the negative thermo element of Type R and Type S thermocouples shall be of a specific Grade, as specified. The purity of platinum before alloying for use in the positive thermo element of Type R, S, and both thermo elements of Type B shall also be of a certain grade, as specified. All material to be supplied shall consist of continuous lengths which shall be free of kinks and shall be round and smooth. Any pits or dents that exceed a certain percentage of the diameter shall be cause for rejection of the material. After material has been processed to its final diameter and prior to subsequent anneal, it shall be cleaned to remove all dirt, lubricant, fingerprints, or other foreign residue. The thermoelements shall be such that, when matched as a thermocouple, the EMF output shall meet the tolerance on the initial value of EMF versus temperature as specified.
SCOPE
1.1 This specification covers non-insulated platinum-rhodium alloys (weight percent composition), and platinum thermoelements that meet the requirement of Specification E230 and NIST Monograph 175.2
1.2 This specification does not cover platinum and platinum-rhodium materials, that 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.
1.3 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.
