[Technical Information] How to detect looseness? (NAS Test)

Testing that emphasizes the impact of accelerated (decelerated) environments and high-temperature environments! Introducing NAS testing!

The NAS test refers to the accelerated vibration test described in the U.S. aerospace standards: NAS (NATIONAL AEROSPACE STANDARD) 3350/3354, which is commonly referred to as the NAS test. Since the test is based on the aviation industry, it emphasizes the effects of acceleration (deceleration) environments and high-temperature environments. At Hard Rock Industries, the "impact vibration test in accordance with NAS3350/3354" is referred to as the NAS test. Additionally, the U.S. aerospace standards primarily focus on heat-resistant alloys for the materials of applicable bolts and nuts, and specify the lubricants to be used, along with various other criteria. To properly conduct a NAS test, it is necessary to adhere to all these standards; however, for products intended for the Japanese market, tests that conform to the NAS test are generally conducted. *For more details, please refer to the PDF document or feel free to contact us.*
