《GB/T 13823.20-2008振动与冲击传感器校准方法 加速度计谐振测试 通用方法》由TC53（全国机械振动、冲击与状态监测标准化技术委员会）归口，主管部门为国家标准化管理委员会。
GB/T 13823《振动与冲击传感器的校准方法》分为20个部分，本部分是GB/T 13823的第20部分。
本部分等同采用ISO 5347-22:1997《振动与冲击传感器校准方法 第22部分：加速度计谐振测试通用方法》（英文版）。
GB/T 13823是由振动和冲击传感器校准方法的系列标准组成。
本部分规定了加速度计谐振测试所需的设备和操作程序。它可以应用于直线式加速度计，例如压阻式、压电式、可变电容式加速度计，适用频率范围50Hz~200kHz。

Scope

GB/T 13823 is composed of a series of standards for calibration methods of vibration and shock sensors. This section specifies the equipment and operating procedures required for accelerometer resonance testing. It can be applied to linear accelerometers, such as piezoresistive, piezoelectric, and variable capacitance accelerometers, and the applicable frequency range is 50Hz~200kHz. Operating procedures are generally opposed to ISO 5347-14, which applies to undamped accelerometers. When a piezoelectric accelerometer is mounted on a structure under test, its frequency response usually depends on the (lowest) resonant frequency of the device. For a given accelerometer, it is difficult to specify a test method for the installation resonant frequency applicable to all installation conditions. This procedure applies only to testing the resonant frequency of an accelerometer under a standard set of repeatable conditions, and the resonant frequency under actual application conditions is likely influence, the resonant frequency will usually be lower). This method is not applicable to the evaluation of installation resonance frequency under site conditions, and the corresponding test method has been given in GB/T 14412-2005.
