Optimized/Harmonized Room Temperature Leakage Test Procedure for Generation of ASME & CEN Code Gasket Factors - Analytical Phase
产生ASME和CEN规范垫片系数的优化/协调室温泄漏试验程序-分析阶段
本公告报告了通用堆芯室温泄漏试验程序,用于生成ASME非强制性附录BFJ草案和CEN EN 1591-1的设计数据。根据拟定的ASTM ROTT草案9[7]或草案10[3]方法,自1994年以来,已根据400多项ROTT试验的结果编制了本工作。没有CEN prEN13555测试数据可用于对该方法进行分析,正如本报告中对ASTM ROTT草案方法所做的那样。ASTM草案和CEN prEN-13555方法(协调点)之间的差异概述如下。实际上,ASTM草案和CEN prEN-13555方法对ROTT垫片试验程序的要求之间只有三个差异。这些差异如下所示:1)流体压力水平,2)垫片应力水平和测试顺序,3)垫片尺寸。对于每一个差异,本报告都包含了一个关于建议的协调方法的结论。
此外,还列出了与拟议协调变更相关的变化或误差水平的度量。与协调方面相关的变化水平应与ASTM ROTT/ASME-BFJ中的总体水平进行比较。
This bulletin reports a common core room temperature leakage test procedure for generation of design data for both the draft ASME Non-mandatory Appendix BFJ and CEN EN 1591-1. The work has been prepared from the results of over 400 ROTT tests performed since 1994 according to the proposed ASTM ROTT Draft 9 [7] or Draft 10 [3] methods. There was no CEN prEN13555 test data available to perform an analysis of the method, as was done for the ASTM ROTT Draft methods in this report. The differences between the draft ASTM and CEN prEN-13555 methods (points of harmonization) are outlined following. There are, in reality, only three differences between the requirements placed on the ROTT gasket test procedure by the draft ASTM and CEN prEN-13555 methods. These differences listed below are:1) fluid pressure level,2) gasket stress levels and test sequence,3) gasket size.For each difference, a conclusion from this report regarding the proposed method of harmonization is included. In addition, a measure of the level of variation or error associated with the proposed harmonization change is also listed. The level of variation associated with that aspect of harmonization should be compared with overall levels found in the ASTM ROTT / ASME-BFJ.
