JJG 652-2012 in English

本规程适用于旋转纯弯曲疲劳试验机的首次检定、后续检定和使用中检查。旋转纯弯曲疲劳试验机主要包括四点受力式旋转纯弯曲疲劳试验机、悬臂式旋转纯弯曲疲劳试验机以及高温旋转纯弯曲疲劳试验机。
其他类型的旋转弯曲疲劳试验机可参照本规程进行检定。

Scope

This procedure applies to the initial calibration, subsequent calibration and in-use inspection of the rotating pure bending fatigue testing machine (hereinafter referred to as the testing machine). Rotating pure bending fatigue testing machines mainly include four-point stressed rotating pure bending fatigue testing machines, cantilever type rotating pure bending fatigue testing machines and high temperature rotating pure bending fatigue testing machines. Other types of rotating bending fatigue testing machines can be calibrated with reference to this procedure.
