AMS 2750
Prepare an enquiry around the applicable pyrometry requirements, equipment configuration and records, rather than treating AMS 2750 as an instrument.
Overview
AMS 2750 is an SAE specification covering pyrometry requirements for equipment used in thermal processing of metallic materials. Its scope includes temperature sensors, instruments, thermal processing equipment, correction factors, system accuracy tests and temperature uniformity surveys. It is a set of requirements, not a piece of equipment.
Start with the revision and additional requirements specified by your customer or process. Identify which activities need attention and share the relevant equipment and records. RTS must confirm the work it can undertake and any required approvals or accreditation; a service enquiry does not establish overall compliance.
What to include in your enquiry
- The specified AMS 2750 revision and any customer or process requirements.
- Furnace or oven identification, process type and operating temperatures.
- Required furnace class and instrumentation type, where specified.
- Sensors, control instruments, recorders and their existing calibration records.
- Whether the request concerns instrumentation, a system accuracy test, a uniformity survey or a combination.
- Previous reports, identified gaps and the documentation required for your review.
Confirm before booking
- Confirm the applicable revision and acceptance requirements with your quality team.
- Agree the exact RTS scope and any necessary customer approval or accreditation.
- Confirm responsibilities for equipment preparation, records and review of the completed work.
Common questions
- Is AMS 2750 a particular calibration instrument?
- No. It is a pyrometry specification. The equipment and checks involved depend on the thermal process, configuration and requirements that apply to your operation.
- Are a system accuracy test and a uniformity survey the same?
- No. A system accuracy test assesses a temperature measurement system, while a uniformity survey examines temperature variation across a defined furnace work zone. Specify which activity you need.
- Does calibrating one instrument demonstrate full AMS 2750 compliance?
- No. Instrument calibration addresses part of a wider set of requirements. Applicable equipment, tests and records also need review against the specified revision and customer requirements.
