Mas 2750. Accessories ams 2750e testing for uniformity ams 2750e testing for uniformity. An instrument that is portable that meets the requirements of table 3 has calibration traceable to secondary equipment or better and is used to conduct on site tests of thermal processing equipment. Section 3 1 7 3 describes the limitations of these type thermocouples. The previous revision of ams 2750 already had restrictions on these types but after providing data of the drift of these thermocouples the team felt further restrictions were required for expendable base metal sat tus sensors.
They define industry specific requirements for heat treatment. Ams 2750e thermocouple requirements metal load thermocouples cannot be recalibrated and are limited to 90 days from first use or 30 uses if used at or below a set point of 1200 f 650 c. Ams2750f results from a five year review and update of the specification. Non expendable base metal load thermocouples also cannot be recalibrated.
Ams 2750e states the following as a way to calculate the sat difference. Office will contact you to select appropriate class and instrumentation type. Ams 2750d 2 2 20 field test instrument. Test to ams 2750 requirements which provides uniformity testing within the effective work space.
Technical changes have been made that resolve issues that were found in the previous revision. Standards such as the ams 2750 e aerospace material specifications are applicable for the industrial processing of high quality materials. Ams 2750 d standard pdf file for free from our online library pdf file ams 2750 d standard working with ams2750e and ams2750d eurotherm april 24th 2018 working with ams2750e and ams2750d what are the differences between ams2750e and regional onsite services for system accuracy tests to national. La norma ams 2750 e e le norme derivate come la ams 2770 per il trattamento termico dell alluminio costituiscono oggi lo standard di riferimento per.
Ams 2750 e aerospace material specifications è uno standard per la lavorazione di materiali di alta qualità nell industria. 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. The difference calculated between the reading of the furnace sensor system being tested sensor lead wire and instrument and the corrected reading of the test sensor system after test sensor and test instrument correction factors are applied shall be recorded as the.
Resolution requirements for recording instruments have been updated to be able to demonstrate that the equipment meets the accuracy tolerances of table 7 when using the percentage instead of the numerical tolerance. Today the ams 2750 e and derivative standards such as ams 2770 for the heat treatment of aluminum are the guidlines for the aerospace industry.
