About This Item
Full Description
1.1''This test method covers a test for determining the thermoelectric electromotive force (emf) of a thermoelement versus National Instruments of Standards and Technology (NIST) platinum 67 (Pt-67) by means of measuring the difference between the emf of the test thermoelement and the emf of a reference thermoelement (previously referred to as a secondary standard), which has a known relationship to NIST Pt-67.
1.2''This test method is applicable to new thermocouple materials over the temperature ranges normally associated with thermocouples and their extension wires. The table on Suggested Upper Temperature Limits for Protected Thermocouples in Specification E230/E230M lists the ranges associated with the letter-designated types of thermocouples. ASTM MNL122 lists the temperature range of extension circuit materials.
1.3''This test method is not applicable to stability testing or inhomogeneity testing.
1.4''The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.5''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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6''This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
