对EN13445液压试验有关规定的理解以及国内外相关标准的比较

Understanding of the Hydraulic Test Standard in EN13445 and Comparison Between the Different Standards Concerned at Home and Abroad

分析和讨论了EN13445规范对液压试验的有关规定,并与国内外的相关规定进行了比较。结果认为,在确定液压试验压力时可采用直接受压元件材料的相应应力比的最大值进行调整,而不必考虑螺栓材料。

The hydraulic test standard in EN 13445 was analyzed and discussed, and compared with the standards concerned at home and abroad. The result shows that it is not necessary to consider the materials of the bolts in determining the hydraulic test pressure, and the maximum value of the corresponding stress ratio of the materials of directly pressured components should be used for adjustment.
