31、tegy As the base standard EN 300 185-1 i contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification EN 300 185-2 121. The criteria applied included the following: - - only the requirements from the point of view of

32、 the T or coincident S and T reference point are considered; whether or not a test case can be built from the TP is not considered. 6.2 User TPs for CONF Ali PICS items referred to in this subclause are as specified in EN 300 185-2 (21 unless indicated otherwise by another numbered reference. 6.2.1
