YY/T 0987.2-2016 Translated English of Chinese Standard. (YYT 0987.2-2016, YY/T0987.2-2016, YYT0987.2-2016): Implants for Surgery - Magnetic Resonance Compatibility - Part 2: Magnetically Induced Displacement Force Test Method
https://www.chinesestandard.net, 2019/03/05 - 17 ページ
This Part of YY/T 0987 includes test method for magnetically induced displacement force generated by medical devices as a result of static gradient magnetic field; a comparison of magnetically induced displacement force and the weight of medical devices. This Part does not involve other possible safety questions. These safety questions include, but are not limited to, magnetically induced torque, radio frequency heating and radio frequency induced heating, noise, interaction among medical devices, functions of medical devices and magnetic resonance system.
