AMS2750 standard is the current standard of high temperature measurement method of aerospace materials used by NASA. The new AMS2750F has carried out the innovation in experience and technical requirements on the E version, which involves the following areas: Temperature sensors, instrumentation, heat treatment equipment, system calibration furnace, furnace temperature uniformity measurement, test, record, etc., the calibration method and frequency and a clear stipulation, macro exhibition in AMS 2750 f is the edition of science and technology based on the experience and technological innovation, independent research and development has the excellent properties of test chamber, to adapt to the changing market changes, In the fierce competition on the torrent!
This standard was proposed by Boeing Company in the United States, and is now widely adopted by aerospace enterprises. What is the background of the implementation of this standard?
In May 2018, the movie "The Captain" was shown in the cinema. The movie tells the story of a flight from Chongqing to Lhasa. At an altitude of 9,800 meters, the front windshield of the right seat of the cockpit suddenly broke and fell off. In the environment not suitable for human survival, captain Liu Changjian still kept calm, race against time, emergency diversion, the plane finally arrived safely in Chengdu Shuangliu airport, all passengers landed safely.
It's based on a true story, it's a thrilling story, and the result is beautiful. By 2020, there had been 363 air accidents in the world, each of which was a near-death experience, which could have been caused by quality problems with aircraft parts, system failures or external force majeure.
Because of the AMS2750's focus on quality and compliance, even a single rivet must be heat-treated according to the standard. How to prove that the heat treatment is strictly in accordance with the standard? The standard stipulates that the heat treatment process data of parts must be unmodified and stored for up to 5 years. In addition to these data, AMS2750 defines:
1. Temperature uniformity TUS in the effective working space. Spare parts must be placed in the effective space of the heat treatment furnace, the furnace to maintain the temperature uniformity of each surface, and the specification of the heat difference range.
2. Types of instruments and meters. According to the requirements of heat treatment process, configuration controller, recorder, thermocouple, etc.
3. System calibration requirements. The instrument, thermocouple and compensation wire must be checked by a qualified third party organization and issued a verification certificate.
4. System accuracy. Whether the calibration data of instrument, thermocouple and compensation wire conform to the standard. Different grades of heat treatment furnace define different system accuracy.
5. Periodic testing and calibration of equipment and corresponding records. The heat treatment furnace shall be regularly checked according to the grade and configuration without interruption. The verification data is unmodifiable and must be stored for five years.
All the above requirements can be found in the standard.
As a 17 years of experience in environmental test chamber, Hongzhan Technology has always cited high standards in the production of environmental test chamber, strict requirements of their own and product equipment research and development.
Hongzhen Technology R&D Center designs and develops high temperature test chamber and heat treatment furnace in accordance with AMS2750E standards, providing reliable instruments and equipment for the test and experiment of new materials, and providing customers with convenient environmental test chamber.
