GENERAL REQUIREMENTS 3.1 Record R

19、etention Supplier must maintain a file for the storage of laboratory reports and calibration records, and establish a record retention policy concerning these records. These records need not follow a standard format but must present the required data in an orderly professional manner. The file must

20、be made available to any and all PPAP approver personnel upon request, includingbut not limited to representatives from the following functions: product engineering, purchasing, quality, and reliability.3.1.1 Objectives of Record Retention The following are the main objectives for retention of test

21、documents or records: 1. Retain records that will evidence compliance so that the supplier can appropriately respond when or if product compliance is challenged. Files must exist for the storage of all laboratory records, data, and calibration records. The files must be available at any time for aud

22、it or inspection. 2. Retain records as needed to assist in evidencing the exercise of “due care” in matters relating to product compliance, government requirements, or product liability. 3. Comply with statutory requirements for the maintenance and retention of specific records. 3.1.2 Retention Meth

23、ods Methods of retention may include retention of original documents, the use of film, or electronic storage equipment. Store records so that they are accessible in a reasonable amount of time. Storage areas should provide adequate protection from unauthorized access, moisture, and fire. 3.2 Sample

24、Documentations and Retention* Engineering test samples must be identified by ANSI Trade Number and serial number unless otherwise noted. Documentation must identify the type of test performed and describe special tests that are not a part of this specification.3.2.1 Required Data Package Supplier mu

25、st submit the data package for the appropriate level of submission to the PPAP approvers responsible engineer and purchasing division for approval signatures. SAE/USCAR-3 REVISION 3 Revised 2009-12 SPECIFICATION FOR TESTINGAUTOMOTIVE MINIATURE BULBS - 5 - 3.2.2 Sample Selection Test bulbs referenced

26、 in this specification are to be selected from the same “Test Lot“. The minimum “Test Lot” is defined as one hour of production. Test bulbs are to be subjected to production intent processing, including final packaging. NOTE: A test sample size of 10 would consist of one sample piece being removed f

27、rom the test lot, every six minutes of production, for a one- hour production run. It is important that the test samples be identified as to location, within the test lot, throughout all testing.3.2.3 Sample Retention Samples tested to attain part approval must be retained by the bulb manufacturer f

28、or a period of time specified in the PPAP Manual. 3.3 Power Sources Supplier must use voltage regulated direct current (DC) power sources for all tests to simulate an automotive battery and charging system. 3.3.1 Output Current The power source must be capable of supplying a continuous output curren

29、t as required by the design loads, including inrush current. Where required to simulate automotive inrush current conditions, an automotive battery or batteries with sufficient cold cranking amps may be connected in parallel with the power supply.3.3.2 Output Voltage The power source must be capable

30、 of supplying an output voltage that must not deviate more than 1.0 volt from the nominal setting over the entire load range (including surges). The power source must recover 63% of its maximum excursion within 5.0 milliseconds. Ripple voltage must not exceed 300 mV peak to peak.Power supplies used

31、for photometric measurements must conform to SAE J1330. 3.4 Equipment Tolerances Supplier must use test setups and equipment capable of measuring test parameters (expressed in nominals) within the limits found in the Equipment Tolerances Table. Equipment Tolerances Table Test Chamber Temperature nom

32、inal 3CTime nominal 0.5% Forces nominal 0.01 N Distances nominal 0.01 mm Voltages nominal 0.01 V for photometrics nominal 0.1 V for all other tests Mean Spherical Candela nominal 2.0% NOTE: Not to be used for performance dependent variable (see Measurement Accuracy section). SAE/USCAR-3 REVISION 3 R

33、evised 2009-12 SPECIFICATION FOR TESTINGAUTOMOTIVE MINIATURE BULBS - 6 - 3.5 Measurement Accuracy Meters and gages used to assess the performance dependent variable, as defined by the basic function of the test sample, must be capable of measuring to one count less than the specified value. For exam

34、ple, even though a 0.1 mm and 0.10 mm wire 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 needed for the second wire. 3.6 Test Repeatability and Calibration 3.6.1 Equipment Repeatability All measu

35、rement equipment used for product evaluation must be repeatable to within 20% of the part tolerance according to Chrysler, Ford, and General Motors Measurement Systems Analysis Reference Manual (AIAG).3.6.2 Equipment Calibration Equipment used for measurement or verification of measurement must be p

36、eriodically calibrated to known standards. Calibration interval must be consistent with industry practices but may not be more than 18 months. 3.6.3 Laboratory Masters Bulbs which are traceable to known standards are laboratory masters. Each supplier must use laboratory masters for comparison measur

37、ements, calibration of test equipment, and for evaluating long-term drift in test equipment. 3.7 Test Default Conditions* When specific test conditions are not given, the following basic conditions apply: Test the bulb with the base and filament parallel to the direction of excitation as shown in fi

38、gure Filament Orientation. Perform tests or measurements at the following ambient conditions:Room Temperature 20C Atmospheric Pressure 650 800 mm Mercury Conduct tests or measurements using the bulbs design voltage as published by the American National Standards Institute, Inc., (ANSI) in Special Re

39、port 25, ANSI Assigned Miniature Lamp Codes. Season the bulbs for 1% of the average life, 10 hours maximum at design voltage, or an equivalent period at a higher (forced) voltage as defined in Accelerated Life section. Note the seasoning method used on the test report. Whenever bulbs are operated at

40、 higher than design voltages, switch them on at their design voltage for at least 50 milliseconds and then step up to the appropriate design voltage. This will limit the inrush current to the design level. 3.8 Test Sharing Within Bulb Families The results of tests performed on one bulb type may, in

41、some cases, be used to indicate the capability of another bulb type within the same bulb family. For example, a crush test performed on a clear, S-8 wedge bulb type may be used as a demonstration of the glass strength of all clear, S-8 wedge bulb types made by the same process from the same glass fr

42、om the same source. Sound judgment must guide this practice. Bulbs within the same bulb family that share components such as glass envelopes, lead wires, filaments, bases, fill gases, etc., may be able to share test results. The PPAP approver will be the final authority on whether this surrogate dat

43、a may be used. 3.9 Test Failure Procedure Should a test fail, contact the requesting party to 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, stop the test until the requesting party can be cont

44、acted. SAE/USCAR-3 REVISION 3 Revised 2009-12 SPECIFICATION FOR TESTINGAUTOMOTIVE MINIATURE BULBS - 7 - 3.10 Control Plans* Supplier must maintain a control plan, consistent with Chrysler, Ford, and General Motors Advanced Product Quality Planning and Control Plan Reference Manual, for each bulb typ

45、e (or bulb family), that contains appropriate controls to ensure that all the significant/critical characteristics covered by the tests in this specification are met. 3.11 Reliability Programs and Methods 3.11.1 Reliability Growth and Ongoing Quality Improvements Bulb suppliers must establish and im

46、plement a plan to improve demonstrated product quality and reliability. They must establish procedures for analyzing and correcting end-of-line defects and predominant failure modes identified by the field return program. True reliability growth occurs when design changes to the bulb or manufacturin

47、g process are made to eliminate the failure modes. 3.11.2 Notification of Process Changes Suppliers must notify the PPAP approver of manufacturing process, material, or design changes to determine if resubmission for PPAP approval is required. 3.11.3 Quality/Reliability Improvement Tools Suppliers m

48、ust use appropriate methods to improve the quality and reliability of their products in accordance with QS-9000. Examples of such methods are Field Return Programs, Design Failure Mode Effects Analysis (DFMEA), Process Failure Mode Effects Analysis (PFMEA), and Fault Tree Analysis (FTA) or Fishbone

49、Diagrams. Further information on these methods is available from the Automotive Industry Action Group (AIAG). 3.12 Hazardous Material Restriction Any regulated substance that is identified by any federal, state, provincial, or local government unit or automotive manufacturer, shall not be used in the manufacturing process of any bulb.Any bulb manufacturer that is currently supplying
