Optimized/Harmonized Room Temperature Leakage Test Procedure for Generation of ASME & CEN Code Gasket Factors - Analytical Phase

Detalles

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.
