eeedf345bea31a43668c7f61aa04eca2 | 186 022-2 | 5.1.2 Test strategy | As the base standard TS 124 615 [1]contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification TS 186 022-1 [2]. The criteria applied include the following: • whether or not a test case can be built from the TP is not considered. |
