44、ee samples are submitted to all the tests and the requirements are satisfied if all the tests are met. If only one of the samples does not satisfy a test due to an assembly or manufacturing fault, that test and any preceding ones which may have influenced the results of the test shall be repeated an

45、d also the tests which follow shall be made in the required sequence on another full set of samples, all of which shall comply with the requirements. NOTE The applicant may submit, together with the number of samples specified in 5.4, the additional set of samples which may be wanted, should one sam

46、ple fail. The testing station will then, without further request, test additional samples and will reject only if a further failure occurs. If the additional set of samples is not submitted at the same time, the failure of one sample will entail rejection. 6 Main characteristics 6.1 The preferred va
