Safety devices for protection against excessive pressure - Part 11: Performance testing

Abstract

The purpose of this document is to define specifically all requirements on tests and laboratory personal, test parameter and its precision and to give options for the testing procedures to be applied for carrying out performance tests on closing, non-reclosing and combined safety devices for protection against excessive pressure as specified in ISO 4126 Parts 1, to 10, with particular reference to type testing. Function and capacity tests of the valve are considered and inlet and outlet conditions are included. Backpressure influence is considered, if necessary. Alternative test rig configurations measurement techniques as well as to testing procedures are given as examples. Further topics to be considered are low and high pressure applications.
