Thus there is a straightforward one-to-one mapping. 7 PCTR conformance A test laboratory, when reques

36、ted by a client to produce a PCTR, is required, as specified in ISO/IEC 9646-5 10, to produce a PCTR conformant with the PCTR template given in annex B of ISO/IEC 9646-5 10. Furthermore, a test laboratory, offering testing for the ATS specification contained in annex C, when requested by a client to

37、 produce a PCTR, is required to produce a PCTR conformant with the PCTR proforma contained in annex A. A PCTR which conforms to this PCTR proforma specification shall preserve the content and ordering of the clauses contained in annex A. Clause A.6 of the PCTR may contain additional columns. If incl

38、uded, these shall be placed to the right of the existing columns. Text in italics may be retained by the test laboratory. ETSI ETSI TS 101 804-3 V2.1.1 (2004-11) 9 8 PIXIT conformance A test realizer, producing an executable test suite for the ATS specification contained in annex C, is required, as

39、specified in ISO/IEC 9646-4 9, to produce an augmented partial PIXIT proforma conformant with this partial PIXIT proforma specification. An augmented partial PIXIT proforma which conforms to this partial PIXIT proforma specification shall, as a minimum, have contents which are technically equivalent

40、 to annex B. The augmented partial PIXIT proforma may contain additional questions that need to be answered in order to prepare the Means Of Testing (MOT) for a particular IUT. A test laboratory, offering testing for the ATS specification contained in annex C, is required, as specified in ISO/IEC 96

41、46-5 10, to further augment the augmented partial PIXIT proforma to produce a PIXIT proforma conformant with this partial PIXIT proforma specification. A PIXIT proforma which conforms to this partial PIXIT proforma specification shall, as a minimum, have contents which are technically equivalent to

42、annex B. The PIXIT proforma may contain additional questions that need to be answered in order to prepare the test laboratory for a particular IUT. 9 ATS conformance The test realizer, producing MOT and ETS for this ATS specification, shall comply with the requirements of ISO/IEC 9646-4 9. In partic

43、ular, these concern the realization of an ETS based on each ATS. The test realizer shall provide a statement of conformance of the MOT to this ATS specification. An ETS which conforms to this ATS specification shall contain test groups and test cases which are technically equivalent to those contain

44、ed in the ATS in annex C. All sequences of test events comprising an abstract test case shall be capable of being realized in the executable test case. Any further checking which the test system might be capable of performing is outside the scope of this ATS specification and shall not contribute to

45、 the verdict assignment for each test case. Test laboratories running conformance test services using this ATS shall comply with ISO/IEC 9646-5 10. A test laboratory which claims to conform to this ATS specification shall use an MOT which conforms to this ATS. ETSI ETSI TS 101 804-3 V2.1.1 (2004-11)
