本标准规定:生成疲劳分布数据的试验和统计方法；验证容积式流体动力泵/电机承压外壳额定压力的试验和统计方法；判断流体动力泵/电机的一种压力能力的通用要求和行业理念；产品比较的统一方法。本标准对以下条件进行了限制:构成或保持承压外壳的元件的恒定振幅、压力诱导载荷；在使用液体而非气体传输功率的系统上使用的泵/电机；至少100000次循环的产品寿命；压力水平和脉冲持续时间的规定条件；从夏比冲击转变温度到蠕变敏感性阈值的温度；与承压外壳材料化学相容的环境； 材料包括铝、镁、钢、铁、铜基合金、钴、钛、不锈钢、镍钢和蒙乃尔合金。特别排除蠕变敏感材料，如:锌、塑料、橡胶和密封装置；本标准涵盖了会导致液体泄漏到环境中的空腔故障。本标准鼓励制造商使用这种常用方法来提高其压力等级的可信度。

This standard provides:test and statistical methods for generating fatigue distribution data;test and statistical methods for conducting a verification of the pressure ratings of the pressure containing envelope on positive displacement fluid power pump/ motor(s);common requirements and an industry-wide philosophy in judging one type of pressure capability for fluid power pump/motor(s);uniform methods of product comparison.This standard limits conditions as follows:constant amplitude, pressure induced loading of the elements that constitute or maintain the pressure containing envelope;pump/motor(s) that are used on systems that use a liquid, rather than a gas to transmit power;product life of at least 100,000 cycles;defined conditions for pressure levels and pulse durations;temperatures from the charpy impact transition temperature to the threshold of creep sensitivity;environments which are chemically compatible with the materials of the pressure containing envelope;materials that are aluminum, magnesium, steel, iron, copper based alloys, cobalt, titanium, stainless steels, nickel steels and monel. Specifically excluded are creep sensitive materials such as: zinc, plastic, rubber and sealing devices;cavity failures that will cause fluid to leak to the environment are covered by this standard.This standard encourages manufacturers to use this common method to enhance the credibility of their pressure ratings.
