3.4 Test tolerances

The requirements given in the present document make no allowance for measurement uncertainty. The test specification TS 37.571-1 defines test tolerances. These test tolerances are individually calculated for each test. The test tolerances are then added to the limits in the present document to create test limits. The measurement results are compared against the test limits as defined by the shared risk principle.

Shared Risk is defined in ETR 273-1-2 [7], subclause 6.5.
