BS EN 62149-1:2012 pdf download – Fibre optic active components and devices – Performance standards Part 1: General and guidance 4 Preparation of a performance standard 4.1 General In the preparation of a performance standard, the following items shall be considered and instructions pertaining to them included. • Product definition • Tests • Details • Requirements • Sample size • Groupings/sequences • Pass/fail criteria • Reference product definition 4.2 Product definition The product to which the performance standard relates shall be clearly defined. 4.3 Tests The tests to be carried out on the product in order for it to meet the performance standard shall be clearly defined. No ambiguity or options shall be allowed. The tests selected combined with the severities/durations, groupings/sequencing, method used and pass/fail criteria should be indicative of a defined product location within a service environment. The test method to be used shall be clearly defined for each test. Wherever possible the testmethod shall be selected from lEC referenced tests; where this is not possible other testmethods may be defined. lf a previously undefined test method is used, the test method anddetails to be specified shall be included in an annex of the performance standard. 4.4Details Severities，durations and the details to be considered， shall be given for all tests andmeasurements presented in a performance standard.These should be directly related to therequirements specified for a product location within a service environment to which theperformance standard is intended to correspond.No ambiguity or options shall be allowed. 4.5Requirements The performance requirements that must be satisfied in order for the product to comply withthe standard shall be specified for each test and/or measurement.No ambiguities shall beallowed. 4.6Sample size The sample size for each test shall be defined in an annex of the performance standard.Nodeviations shall be allowed. 4.7Groupings/sequences Test groups and test sequences shall be defined in an annex as required by the user,usergroup or manufacturer. The number of samples for each test group shall also be defined inthe annex. Where prohibitive cost is associated with the active devices,numbers of samplesmay be reduced. 4.8Pass/fail criteria The pass/fail criteria shall be unambiguously stated for each test within the performancestandard. No deviation or exceptions shall be allowed. 4.9Reference product definition Where a reference product is called for in any of the test and measurement methods usedwithin a performance standard,the reference product shall be clearly defined in an annex ofthe performance standard. 4.10 Performance...
