1.1本标准规定:-生成疲劳分布数据的试验和统计方法；-验证快接管接头额定压力的试验和统计方法；-判断快接管接头的一种压力能力的通用要求和全行业理念；-产品比较的统一方法。1.2本标准对以下条件进行了限制:-恒定振幅的压力诱导荷载；-至少100000次循环的产品寿命；-NFPA/T2中定义的压力水平和脉冲持续时间。6.1 R2第8条；-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中的材料具有化学相容性的环境材料包括铝、镁、铁、钢、不锈钢、钴、钛、铜基合金、镍基合金或蒙乃尔合金。特别排除蠕变敏感材料，如锌、塑料、橡胶和密封装置； -通过线性或旋转运动或两者连接和断开的快接管接头；-断开时，带或不带密封装置的快接管接头。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 verifying the pressure ratings of quick-action couplings;- common requirements and an industry-wide philosophy for judging one type of pressure capability for quick-action couplings;- uniform methods of product comparison.1.2 This standard limits conditions as follows:- pressure-induced loadings of constant amplitude;- product life of at least 100,000 cycles;- pressure levels and pulse durations as defined in NFPA/T2.6.1 R2, clause 8;- temperatures that range from the Charpy impact transition temperature to the threshold of creep sensitivity;- environments which are chemically compatible with the materials in the pressure-containing envelope;- materials that are aluminum, magnesium, iron, steel, stainless steel, cobalt, titanium, copper-based alloys, nickelbased alloys, or monel. Specifically excluded are creep-sensitive materials such as zinc, plastic, rubber and sealing devices;- quick-action couplings which are connected and disconnected by a linear or rotational motion, or both;- quick-action couplings with or without sealing means when uncoupled.1.3 This standard encourages manufacturers to use this common method to enhance the credibility of their pressure ratings.
