标准摘要
[中文适用范围]： 本文件规定了高速拉伸试验数据的验证程序。 它规定了高速拉伸试验设备的力传感器和夹具配置的固有振荡频率频谱的确定方法。 最低有效频率用于验证。 该验证程序仅适用于高速拉伸试验机中使用的力测量系统，该系统显示出对所获得的结果可能至关重要的共振影响水平。 一旦系统的相关频率和给定材料的预期应变已知，该方法也可以计算理论最大允许测试速度。 [外文原描述]： This document specifies procedures for validation of high-speed tensile test data. It specifies a method to determine the spectrum of the natural oscillation frequencies of the force transducer and grip configuration of the high-speed tensile test equipment. The lowest significant frequency is used for the validation. This validation procedure only applies to force measurement systems used in high-speed tensile testing machines showing a level of resonance influence that could be critical to the obtained result. Once the relevant frequencies of the system and the anticipated strain for the given material are known, this method allows to calculate the theoretical maximum allowed test speed too.
