本报告第1部分包括文件PVP2006-ICPVT11-94010，“压力容器规范ASME第八节和EN13445的比较”本文对美国机械工程师学会（ASME）锅炉及压力容器规范第八节和欧洲压力容器规范EN13445（EN）的主要技术、商业和使用差异进行了比较研究。本研究包括对欧盟委员会（EC）发布的“压力设备标准比较研究”的审查，并提供了规范设计要求、材料性能、制造和对总成本的影响之间的技术比较。这项研究的目的是提供一个广泛的观点，在选择最合适的容器设计代码时要考虑的主要差异和因素。 本报告第二部分包括文件PVP2006-ICPVT11-93059，“ASME第八节和EN 13445带焊接接头容器的设计疲劳寿命比较”EC进行的“压力设备标准对比研究”包括ASME锅炉及压力容器规范（B&PVC）第八节允许的焊接容器的设计疲劳寿命与欧洲标准EN 13445的设计疲劳寿命的比较。据报道，ASME规范的允许循环次数远大于EN 13445，因此，ASME规范被视为对焊接区域不保守。本文调查了两个设计规范之间报告的差异的原因，确定了EC计算中的错误，根据ASME规范规则重新计算了允许循环，并得出结论，它们与EN 13445的循环具有可比性。

Part 1 of this report includes paper PVP2006-ICPVT11-94010, "Comparison of Pressure Vessel Codes ASME Section VIII and EN13445." This paper consists of a comparative study of the primary technical, commercial, and usage differences between the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section VIII and the European Pressure Vessel Code EN13445 (EN). This study includes a review of "Comparative Study on Pressure Equipment Standards" published by the European Commission (EC) and provides technical comparisons between the code design requirements, material properties, fabrication, and contributing effects on overall cost. This study is intended to provide a broad viewpoint on the major differences and factors to consider when choosing the most appropriate vessel design code to use. Part II of this report includes paper PVP2006-ICPVT11-93059, "Design Fatigue Life Comparison of ASME Section VIII and EN 13445 Vessels with Welded Joints." The "Comparative Study on Pressure Equipment Standards" performed by the EC included a comparison of design fatigue life of welded vessels allowed by the ASME Boiler and Pressure Vessel Code (B&PVC) Section VIII with that of the European Standard EN 13445. The allowable number cycles of the ASME Code was reported to be much larger than that of EN 13445, and, therefore, the ASME Code was regarded as unconservative for welded regions. This paper investigates the reason for the reported discrepancy between the two design codes, identifies errors in the EC calculation, recalculates the allowable cycles according to ASME Code rules and concluded that they are comparable with those of EN 13445.
