For each type of test, i.e.

26、 type testing (TT), batch release test (BRT), process verification test (PVT), and audit test (AT), this part of EN 12201 details the applicable characteristics to be assessed as well as the frequency and sampling of testing. A typical scheme for the assessment of conformity of compounds, pipes, fit

27、tings, valves, joints or assemblies by manufacturers is given in Figure 1.
