AMS 2750G refers to the Aerospace Material Specification for pyrometry, which is related to thermal processing equipment used in metal heat treatment processes. The specification is part of the SAE (Society of Automotive Engineers) standards.
TUS stands for Temperature Uniformity Survey. A TUS report is a document that provides evidence that a particular piece of thermal processing equipment, such as a furnace or oven, is able to maintain a temperature within a specified range throughout its working volume. This is critical for processes that require precise temperature control to ensure the quality and consistency of the heat-treated parts.
Here’s what’s typically included in a TUS report:
- Identification: Details of the furnace or oven, including make, model, serial number, and any other identifiers.
- Survey Results: Data showing the temperatures recorded at various locations within the equipment’s working area to demonstrate uniformity.
- Methodology: Information on how the TUS was conducted, including the type of sensors used, their calibration status, and the locations within the furnace where the measurements were taken.
- Analysis: Interpretation of the data against the AMS 2750G standard requirements, showing whether the equipment meets the specified temperature uniformity criteria.
- Action Points: If there are areas where the equipment does not meet the required standards, the report may include recommendations for adjustments or repairs.
- Approval: Signatures or approvals from qualified personnel attesting to the validity of the survey and its findings.
AMS 2750G TUS reports are essential for aerospace and other industries where the properties of heat-treated materials are critical to the performance and safety of the final product.

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.
