REQUEST FOR RELIEF PV-33 System All systems Test Requirement Analysis of test data within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> per IWP - 1220.
Basis for Relief Due to the time involved in processing surveillance instructions to the reviewer and the possibility of weekends and/or holidays falling between running tests and completely reviewing the results, 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> is impractical.
Alternate Testing Pump parameters of flow rate and differential pressure will be reviewed immediately af ter the test to vetify that they do not fall within the " Required Action Range" of Table IWP-3100-2. Complete analysis of test data will be performed within 4 working days of the test.
