19、n proposals, or determining root causes of field problems.3.4.1 Validation Tests: Validation tests or sample approval tests are acceptance-type tests. Consideration shall be given to the inherent repeatability or subjectivity of certain tests outlined by this specification before designation as a va

20、lidation or compliance test.SAE/USCAR-13 August 1999STANDARD FOR IN-TANK ELECTRIC FUEL PUMPS-4-4.0 GENERAL REQUIREMENTS:4.1 Record Retention:The supplier shall maintain a central file for the storage of laboratory reports and calibrationrecords. A record retention policy concerning these records sha

21、ll comply with QS-9000.Customer specific files shall be made available to any and all customer personnel upon request, including but not limited to representatives from the following functions: product engineering, purchasing, quality, and reliability.4.1.1 Objectives of Record Retention: The follow

22、ing are the main objectives for record retention:A. Retain records that will evidence compliance so that the supplier can appropriatelyrespond when or if product compliance is challenged. Files shall exist for the storage of all laboratory records, data, and calibration records. The files shall be a

23、vailable at any time for audit or inspection.B. Retain records as needed to assist in evidencing the exercise of “due care“ in matters relating to product compliance to government requirements or product liability.C. Comply with statutory requirements for the maintenance and retention of specific re

24、cords to substantiate compliance with legal requirements.4.1.2 Retention Methods: Method of retention must conform to the suppliers corporate procedures and may include retention of original documents, the use of film, or electronic storage equipment. Records must be stored so that they are accessib

25、le in a reasonable amount of time. Storage areas should provide adequate protection from unauthorized access, moisture, and fire.4.2 Sample Documentation:Engineering test samples shall be identified by part number and serial number unless otherwise noted.4.2.1 Required Data Package:4.2.2 Master Samp

26、les: Master samples for performance, noise, or construction, if required by the customer, will be provided at the time of approval.4.3 Sample Sizes:Sample sizes will be documented in the application specification.SAE/USCAR-13 August 1999STANDARD FOR IN-TANK ELECTRIC FUEL PUMPS-5-4.4 Materials and Pr

27、ocess Standards:Suppliers are expected to subscribe to appropriate Materials and Process Standards that are called out by this specification.The supplier shall not change any material or process requirements subsequent to Design Verification approval without the written consent of the customers rele

28、asing department.Unless otherwise specified or required by law, suppliers should use the most recent versions of any applicable reference documents or standards.4.5 Measurement Resolution:Meters and gages used in measurements of the test sample shall be capable of measuring to one count less than th

29、e specified value. For example, even though a 0.1 mm and 0.10 mm might be the same diameter, calipers capable of 0.01 mm resolution may be used to measure the first wire but a micrometer with 0.001 mm resolution is required to measure the second wire.4.6 Test Repeatability and Calibration:Repeatabil

30、ity studies shall be performed on all laboratory equipment after initial calibration and before use for product evaluation. Individual gages and meters must be calibrated to the manufacturers specifications on a regular basis.4.7 Conformance Determination:Test conformance shall be determined by the

31、performance requirements of the test being performed. All samples shall satisfy the performance requirements regardless of age, cycles, or temperature, unless otherwise noted on the part drawing.4.8 Disposition of Samples:Should a premature test nonconformance occur, contact the requesting party to

32、determine if the test is to be continued to gain additional product experience or if testing is to be suspended. When contact cannot be immediately made, the type of test shall determine the disposition of the samples. If the test order indicates that the test is investigative in nature, continue un

33、til the requesting party or parties are available. If the test order is for sample approval or validation, stop the test until the requesting party can be contacted.SAE/USCAR-13 August 1999STANDARD FOR IN-TANK ELECTRIC FUEL PUMPS-6-4.9 Quality Control:A supplier who furnishes finished parts is respo

34、nsible for the quality of all components of the shipped assembly or end item, whether component parts are processed/manufactured by the supplier or purchased from another source. If required, parts shall be purchased only from customer-approved sources.4.10 Pump Performance Stabilization:Before test
