Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed and managed by the National Technical Committee for Standardization of Mechanical Vibration, Shock and Condition Monitoring (SAC/TC53). This standard was drafted. China Aviation Industry Corporation Beijing Great Wall Metrology and Testing Technology Research Institute, China Institute of Metrology, Su State Dongling Vibration Test Instrument Co., Ltd., Zhejiang Institute of Metrology. The main drafters of this standard. Cao Yiqing, Li Shanming, Meng Feng, He Xuan, Yang Jun, Xu Man, Zeng Limin. Dynamic force sensor calibration method impact force calibration

1 Scope

This standard specifies the methods and operating procedures for calibrating dynamic force sensors using the impact force method. This standard is applicable to the peak of impact force of 20N~200kN, and the duration of impact force pulse is within the range of 0.5ms~10ms. The dynamic force sensor is calibrated for impact sensitivity.
