27、tive): HS Requirements and conformance Test specifications Table (HS-RTT) The HS Requirements and conformance Test specifications Table (HS-RTT) in table A.1 serves a number of purposes, as follows: it provides a statement of all the requirements in words and by cross reference to (a) specific claus
28、e(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 requirements by cross reference to (a) specific clause(s) in the present document or to (a) specific clause(s) in (a) specific r
29、eferenced document(s); it qualifies each requirement to be either: - Unconditional: meaning that the requirement applies in all circumstances; or - Conditional: meaning that the requirement is dependent on the manufacturer having chosen to support optional functionality defined within the schedule;
30、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: - Essential: meaning that it is included with the Essential Radio Test Suite and therefore the requirement shall be demonstrate
31、d 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 requirement are permitted.

The completion of all tests c
33、lassified “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
34、 an equivalent test or by manufacturers assertion supported by appropriate entries in the technical construction file.
