33、 of purposes, as follows: it provides a statement of all the requirements in words and by cross reference to (a) specific clause(s) in the present document or to (a) specific clause(s) in (a) specific referenced document(s); it provides a statement of all the test procedures corresponding to those r
34、equirements by cross reference to (a) specific clause(s) in the present document or to (a) specific clause(s) in (a) specific referenced document(s); it qualifies each requirement to be either: - Unconditional: meaning that the requirement applies in all circumstances; or - Conditional: meaning that
35、 the requirement is dependent on the manufacturer having chosen to support optional functionality defined within the schedule. in the case of Conditional requirements, it associates the requirement with the particular optional service or functionality; it qualifies each test procedure to be either:
36、- Essential: meaning that it is included with the Essential Radio Test Suite and therefore the requirement shall be demonstrated to be met in accordance with the referenced procedures; - Other: meaning that the test procedure is illustrative but other means of demonstrating compliance with the requi
37、rement are permitted. Table A.1: HS Requirements and conformance Test specifications Table (HS-RTT) Harmonized Standard EN 302 998-1 The following requirements and test specifications are relevant to the presumption of conformity under the article 3.2 of the R those designated “O“ make up the Other
38、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
39、 “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 manufacturers assertion supported by appropriate entries in the technical construction file.
