6 Mandatory Tests 6.1 Test Conditions Identify the important test condition variables which should be measured and recorded before, during, and/or after each test and document that its value did not vary beyond the allowable limits. Due to limitations of the test facility, it may not be possible to evaluate the influence of certain parameters over the entire range specified for the device. The testing protocol should specify that the test report include a list of those parameters which may affect the performance of the device, but were not tested. The manufacturer shall specify performances within the range that the equipment was tested. 6.2 Test Installation If applicable, the testing protocol should define the type of test installation needed to evaluate the effects of the important test condition variables on device performance. For critical measurements, the test protocol should define the allowable precision limit of the test equipment and which measuring devices should be required to record and document the traceability to a national standard (e.g. NIST). 6.3 Test Results The parameter(s) defining the performance of the device (i.e. test results) shall be recorded during and after each test. Additional recording requirements shall be specified in the individual sections of the testing protocols as needed. 6.4 Baseline (Ideal Condition) Testing In order to identify the influence of certain parameters or changes to the operating condition, ideal or baseline test(s) are necessary. The testing protocol should define the test conditions which may be considered as the ideal or baseline test(s). The document should define, if applicable, the type and frequency of baseline testing needed to verify the reproducibility of the tested device. NOTE The test facility uncertainty should be considered for calculations of acceptable reproducibility.
6.6 Special Testing Special tests may be defined where the combined effect of variations in multiple factors may be tested to reduce the cost of performance testing of the device. Whenever possible, tests should be designed to produce results to reflect the influence of one well-defined variable at a time. 6.7 Testing Documentation All data used to calculate the final or intermediate result shall be recorded, attested, and/or certified by the test facility. If tests are performed at a third party facility, results shall be retained for future reference. These test results shall be retained for the period of time defined by the document. If a specific test report is not published in the public domain and is not available for verification of the performance claim, the associated claim will be deemed unverifiable. 6.8 Testing Procedure The document shall describe in detail how the tests are to be conducted or reference other published procedure(s) for similar type tests, if type testing is permitted for the device. 7 Test Facility Requirements 7.1 Audit Process To assure adherence to the testing protocols defined in this chapter, the laboratory or testing facility performing the tests shall provide documentation that the tests are performed in accordance with the standard. This documentation shall be provided at the request of any user of the facility. The user of the facility can request an audit of the laboratory or the testing facility to ensure the validity of the tests. The depth of the audit is determined by the user of the facility and shall be consistent with relevant national and/or international standards. The user of the facility may require the laboratory or testing facility to be traceable to national or international standards of weights and measures. The laboratory or testing facility shall provide documentation of how it estimates the uncertainty of its systems and procedures and how that uncertainty is maintained throughout the testing process under this protocol.
