permissives • operation of standby power system logic and its loading sequence • calibration of relays (degraded grid voltage and loss of voltage) • control transformer settings • temperature effects • range checks • response times b. Test Objectives Objectives of the test should be clearly stated. Many systems tests will be intended to demonstrate that each of several initiation events will produce one or more expected responses. These initiating events and the corresponding responses should be identified. 2 Regulatory Guide 1.37, “Quality Assurance Requirements for Cleaning of Fluid Systems and Associated Components of Water-Cooled Nuclear Power Plants,” (Ref. 42) should be used as guidance. Appendix C to DG-1259, Page C-4 c. Special Precautions The test procedure should highlight and clearly describe any and all special precautions needed to ensure a reliable test or the safety of personnel or equipment. d. Initial System Conditions Where appropriate, instructions should be given pertaining to the system configuration, components that should or should not be operating, and other pertinent conditions that might affect the operation of the given system. e. Environmental Conditions Most tests will be run at ambient conditions; however, procedures should include provisions to test the equipment under environmental conditions as close as practical to those the equipment will experience in both normal and accident situations. f. Acceptance Criteria The test procedure should clearly identify the criteria against which the success or failure of the test will be judged and should account for measurement errors and uncertainties. In some cases, these will be qualitative criteria. Where applicable, quantitative values, with appropriate tolerances, should be used as acceptance criteria. g. Data Collection The test procedure should prescribe the data to be collected and the form in which the data are to be recorded. All entries should be permanent. The
