1. SCOPE:
1.1 This specification covers pyrometric requirements for thermal processing equipment used for
heat treatment. It covers temperature sensors, instrumentation, thermal processing equipment,
system accuracy tests, and temperature uniformity surveys. These are necessary to ensure that
parts or raw materials are heat treated in accordance with the applicable specification(s).
1.2 This specification is not applicable to heating, or to intermediate thermal processing unless
specifically referenced by a material or process specification.
1.3 This specification applies to laboratory furnaces to the extent specified in 3.6.
2. APPLICABLE DOCUMENTS:
The issue of the following documents in effect on the date of the purchase order forms a part of
this specification to the extent specified herein. The supplier may work to a subsequent revision of
a document unless a specific document issue is specified. When the referenced document has
been canceled and no superseding document has been specified, the last published issue of that
document shall apply.
