规定了开式前机械动力压力机的几何试验，并给出了相应的允许公差。它适用于一般用途和正常精度高达2500 kN容量的机器，仅涉及机器精度的验证。它不适用于机器运行的测试（振动、异常噪音、部件的粘滑运动等）或其特性（速度、进给等），通常应在测试精度之前进行检查。

Specifies geometrical tests on open front mechanical power presses and gives the corresponding permissible tolerances. It is applicable to machines of general purpose use and normal accuracy up to 2 500 kN capacity, and deals only with the verification of the accuracy of the machine. It does not apply to the testing of the running of the machine (vibrations, abnormal noises, stick-slip motion of components etc.), or to its characteristics (speeds, feeds, etc.), which should generally be checked before the accuracy is tested.
