The new siblings to the AMS2750 standard: AMS2750/1, AMS2750/2 and AMS2750/3

The AMEC ( Aerospace Metals Engineering Committee ) , which published AMS2750, the reference document on pyrometry for the entire heat treatment industry, is finalizing its preparations.

The committee, having decided to address some issues not covered or detailed in AMS 2750 with three different standards, will soon publish these three brand-new standards. Naturally, these three standards will, in addition to the requirements of AMS 2750 (the older sibling in the hierarchy), define exceptions and additions regarding pyrometry for non-metallic materials, HIP ( Hot Isostatic Press ) equipment, and heat treatment tools (fixtures, etc.).

Because they are not yet published and are in draft form, their names begin with the committee's name.

These,

1. AMECAMS2750/1 - Pyrometer for Nonmetallic Processing :

   This standard, together with AMS2750, will cover pyrometric requirements for equipment used in the heat treatment of non-metallic products. Specifically, it will describe temperature sensors, measuring instruments, heat treatment equipment, correction factors and instrument deflections, system accuracy tests, and temperature homogeneity investigations. These are necessary to ensure that products are cured or shaped in accordance with the relevant specifications. This specification will also cover pressure or vacuum requirements for heat treatment equipment.

   
   

2. AMECAMS2750/2 - Pyrometry for Hot Isostatic Pressing:

   Original equipment manufacturers' (OEMs) hot isostatic pressing (HIP) specifications are numerous, but their pyrometry requirements are neither comprehensive nor consistent. This AMS specification is intended to be published for acceptance by HIP equipment manufacturers and processors as a technically valid specification providing robust pyrometry requirements across the aerospace industry.

   
   

3. AMECAMS2750/3 - Pyrometry for Heat Tooling:

   The committee has not yet created a statement page for this standard. My guess is that it will be a standard for parts such as tools and fixtures used in heat treatment equipment. This section of the text will be revised when a statement is released.

The AMEC designation will be removed from the names once the standards come into effect.

• AMS2750/1 - Pyrometer for Nonmetallic Processing

• AMS2750/2 - Pyrometry for Hot Isostatic Pressing

• AMS2750/3 - Pyrometry for Heat Tooling

As always, we will promptly prepare an assessment of these standards as soon as they are published and release it on our blog as BDI Metal .
