标准摘要
[中文适用范围]： 为了进行单轴测试系统的动态校准，需要测量测试件所受的力，以达到已知的准确度水平——这个测量是通过动态校准装置（DCD）代替测试件进行的，校准方法在ISO 4965-1中描述。本部分ISO 4965定义了DCD仪器的校准程序。还描述了结果分析方法，得出仪器与ISO 4965-1一致的DCD一起使用的有效测试频率范围。 [外文原描述]： In order to perform a dynamic calibration of a uniaxial testing system, it is necessary to measure the forces experienced by the test-piece to known levels of accuracy; this measurement is made by a dynamic calibration device (DCD) in place of the test-piece and the calibration method is described in ISO 4965-1. ISO 4965-2:2012 defines the calibration procedure for the DCD's instrumentation. The method for the analysis of the results is also described, leading to a range of testing frequencies over which the instrumentation is valid for use with DCDs in accordance with ISO 4965-1.
