The changes from AMS2750F to AMS2750G include revisions and updates to the pyrometric requirements for equipment used in the thermal processing of metallic materials. The AMS2750G specification covers temperature sensors, instrumentation, thermal processing equipment, correction factors and instrument offsets, system accuracy tests, and temperature uniformity surveys. These changes are necessary to ensure that parts or raw materials are heat treated in accordance with the applicable specifications. The purpose of AMS2750G is to ensure that parts or raw materials are heat treated in accordance with the applicable specifications.
The revision from AMS2750F to AMS2750G mainly consists of administrative changes rather than significant technical changes. One notable change is that digital recording instruments are not required to read to the tenth of a degree until one year after the release of AMS2750G. Additionally, over temperature controls have been given a permitted error within AMS2750G, which was not present in revision F.
To comply with AMS2750G, suppliers who already conform to AMS2750F should find the transition relatively straightforward. It is recommended to consult experts or training courses that specialize in AMS2750 standards and Nadcap requirements to ensure compliance. Calibration services and process certification services can also be helpful in meeting industry standards.
Some specific changes between AMS2750F and AMS2750G include:
Revision G marking: Historically, AMS2750 did not mark the revision when released using change bars, unlike other AMS specifications. However, when AMS2750F was revised to revision G, change bars were included. This makes it easier for suppliers to understand the modifications and account for those changes internally.
Extensive changes: AMS2750G is considered a complete rewrite of the specification, and there are no change bars to indicate specific changes. The changes are extensive and cover various aspects of pyrometry requirements.
It is important to refer to the official AMS2750G specification for a comprehensive understanding of all the changes and updates.
