5、cility Audit Process RATIONALETest facilities are frequently audited by various authorities, regulatory bodies, gas turbine engine OEMs and customers. The main purpose of the audit process is to ensure that the test cell operator/owner provides evidence that the facility is maintained in such a way

6、that it meets the requirements set by the OEM and authorizing bodies and that the test cell meets the conditions set in the correlation process. This document describes guidelines and criteria to audit a test facility both from an auditor perspective in addition to the user/owners perspective. SAE A

To assure the test cell is constant in compliance with all audit requirements, a configuration control system, performance trend analysis plan as well as a frequent maintenance and inspection pla

45、n must be in place. 5.1 Configuration Control Configuration control is the process that assures that the test cell remains in the condition at time of the correlation(s). To assure this, the test cell configuration during correlation must be well documented, hardware locations in the test cell ident

46、ified and positions marked. Any changes to the test cell layout which may have effect on the configuration like maintenance, repair and alterations should be investigated and if required, verified by back to back tests. For further information regarding configuration control refer to ARP6028. All ch

47、anges must be documented in the facilty operations manual or any other documents like maintenance logs. 5.2 Performance Trend Analysis In order to assure that measured and calculated performance is still within correlation tolerances an active performance trend analysis system that conducts active t

48、rending of the specified performance parameters must be in place. For further information regarding trend analysis methods refer to ARP5758.
