10 10 EN V1.5.1 ( ) 5.2 Interpretation of the measurement results The interpretation of the results recorded in a test report for the measurements described in the present document shall be as follows: - the measured value related to the corresponding limit will be used to decide whether equipment meets the requirements of the present document; - the value of the measurement uncertainty for the measurement of each parameter shall be included in the test report; - the recorded value of the measurement uncertainty shall be, for each measurement, equal to or lower than the figures in table 1. For the test methods, according to the present document, the measurement uncertainty figures shall be calculated in accordance with TR [3] and shall correspond to an expansion factor (coverage factor) k = 1,96 or k = 2 (which provide confidence levels of respectively 95 % and 95,45 % in the case where the distributions characterising the actual measurement uncertainties are normal (Gaussian)). Table 1 is based on such expansion factors.

A textual reference to the requirement. Identification of clause(s) defining the requirement in the present document unless another document is referenced explicitly. Requirement Conditionality: U/C Condition Indicates whether the requirement is to be unconditionally applicable (U) or is conditional upon the manufacturers claimed functionality of the equipment (C). Explains the conditions when the requirement shall or shall not be applicable for a technical requirement which is classified "conditional".
14 14 EN V1.5.1 ( ) Test Specification: E/O NOTE: Indicates whether the test specification forms part of the Essential Radio Test Suite (E) or whether it is one of the Other Test Suite (O). All tests whether "E" or "O" are relevant to the requirements. Rows designated "E" collectively make up the Essential Radio Test Suite; those designated "O" make up the Other Test Suite; for those designated "X" there is no test specified corresponding to the requirement. The completion of all tests classified "E" as specified with satisfactory outcomes is a necessary condition for a presumption of conformity. Compliance with requirements associated with tests classified "O" or "X" is a necessary condition for presumption of conformity, although conformance with the requirement may be claimed by an equivalent test or by manufacturer's assertion supported by appropriate entries in the technical construction file. Clause Number Identification of clause(s) defining the test specification in the present document unless another document is referenced explicitly. Where no test is specified (that is, where the previous field is "X") this field remains blank.
15 15 EN V1.5.1 ( ) Annex B (informative): The EN title in the official languages The enlargement of the European Union (EU) resulted in a requirement from the EU for a larger number of languages for the translation of the titles of Harmonized Standards and mandated ENs that are to be listed in the Official Journal to support the implementation of this legislation.
