1.1本标准规定:-生成疲劳分布数据的试验和统计方法；-流体动力液压过滤器压力额定值验证的试验和统计方法 /分离器壳体判断流体动力液压过滤器/分离器壳体的一种压力能力的一般要求和行业理念产品比较的统一方法。1.2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； -至少100000次循环的产品寿命；-压力水平和脉冲持续时间的定义条件；-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铝、镁、钢、铁、铜基合金、钴、钛、不锈钢、镍钢和蒙乃尔合金材料特别排除蠕变敏感材料，如:锌、塑料、橡胶和密封装置排除液压过滤器/分离器外壳（如旋转）的有限寿命RFP额定值- 在有限寿命应用中使用。参见ANSI/（NFPA）T3。10.17.1.3本标准鼓励制造商使用这种常用方法来提高其压力额定值的可信度。

1.1 This standard provides:- test and statistical methods for generating fatigue distribution data;- test and statistical methods for conducting a verification of the pressure ratings on fluid power hydraulic filter /separator housing(s);- common requirements and an industry-wide philosophy in judging one type of pressure capability for fluid power hydraulic filter/separator housing(s);- uniform methods of product comparison.1.2 This standard limits conditions as follows:- constant amplitude, pressure induced loading of the elements that constitute or maintain the pressure containing envelope;- 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;- to exclude the finite life RFP rating for a hydraulic filter /separator housing (such as spin-on filters) used in finite life applications. See ANSI/(NFPA)T3.10.17.1.3 This standard encourages manufacturers to use this common method to enhance the credibility of their pressure ratings.
