1.1''This guide covers the use of ANSI thermocouple Types listed in Specification E230/E230M for elevated-temperature mechanical testing at temperatures typical in testing of metals.

Note 1:''Typical conditions for mechanical testing are specified temperatures up to 1800'''''F (982'''''C) in air at one atmosphere of pressure.

1.1.1''This guide focuses on most commonly used base metal and noble metal ANSI type K, N, R, and S thermocouples.

1.1.2''Other ANSI thermocouple types that are listed in Specification E230/E230M may be used if the specific precautions and maximum temperatures for their use are followed.

1.1.3''It does not cover the use of sheathed thermocouples.

1.2''The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4''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.
