2、ion Note: Nothing in this specification supersedes ap- plicable laws and regulations unless a specific ex- emption has been obtained. Note: In the event of a conflict between the English band the domestic language, the English language shall take precedence. Note: In the case when multiple procedure
3、s are listed to conduct a validation test, the VEC is the final arbiter on selecting the appropriate test method. 1.1 Scope. This specification sets forth the valida- tion procedures and associated performance re- quirements for Side Impact Airbag and Roof Rail Airbag Module assembly (hereinafter re
4、ferred to as the Module) that will be used for side airbag sys- tems in GM vehicles. This document does not ad- dress developmental test requirements. It shall be the responsibility of the supplier to identify and conduct a Development and Concept Validation Test Plan as defined in the program State
5、ment of Requirements, and/or the DFMEA/PFMEA. Module Development Testing shall be completed prior to start of DV Testing. The Module Validation Test Plans shall be struc- tured in accordance to the DV (4.2.1.1 and 4.2.1.2) PV Test Matrixes (4.2.2.1 and 4.2.2.2) in this document. These requirements s
6、hall contain but not be limited to a minimum set of tests and sam- ple sizes for validating Modules. It shall be the Suppliers responsibility to evaluate the plans and determine if additional testing and/or larger sample sizes are recommended based on the suppliers developed DFMEA and PFMEAs. The Mo
7、dule De- velopment, DV, and PV Test Plans shall be ap- proved by the Responsible VEC Engineer prior to implementation. 1.2 Mission/Theme. The Module supplements the protection offered by the vehicle structure, seat belt system, and interior trim for near-side side impact collisions. The Module is in
8、tended to reduced injury potential in those accidents where there is a sig- nificant risk that the outboard front seat occupant might otherwise be injured, meet applicable regula- tions, and address GM Worldwide performance goals. 1.3 Classification.

11、uirements The use of shall in this document denotes a bind- ing provision that must be met unless a deviation is granted by the Responsible VEC(s). Deviations to shall requirements will only be considered and, if approved, granted by the Responsible VEC(s) after evaluating appropriate available tech

The term airbag refers to the airbag subsystem and not a specific component (i.e. the cushion). Test Equip
14、ment shall be utilized as specified, by the indicated test procedures, standards and speci- fications. Test Equipment. Unless otherwise specified elsewhere in this document, tests shall be conducted at local ambi- ent pressure, relative humidity, and room tempera- ture 23 5C. Unless otherwise specif
15、ied in this document, test condition tolerances shall be as follows: Temperature 3C Relative Humidity 10% of R.H. Vacuums 10 mm of Hg Height 0.05 m Acceleration 2% except were minimums are stated Frequency 4% or 2 Hz, whichever is greater Amps 0.01 A Volts 5% Ohms 1.0% All test conditions shall be w

18、xtures and Equipment: Conditioning chamber, capable of holding 30 to +85C. Rigid fixture that represent in-vehicle module orientation and mounting system. Module mounting shall simulate vehicle envi- ronment, including reaction surfaces when appli- cable. Cover and/or door required. Actuation device
19、 that also switches on the measuring equipment. Approved Data Acquisition System. High Speed cameras or videos (1000 frames/minimum), two required. (Three cam- eras/videos preferred: front, side, and oblique views.) Lights (high intensity). Pressure Transducer that can measure pres- sures up to 690
20、kPa. Thermometers that can measure temperatures up to +110C. Strobe Light (to indicate T = 0). ID-labels (with test number). Data Required: Conditioning temperature and ambient tempera- ture in test cell during the test. Cushion pressure vs. time (If requested). Voltage and current vs. time. High Sp
21、eed Films. Test Procedure: a. Set up and adjust high speed cameras. Stan- dard camera coverage is one camera in front and one camera on either side. Each camera should have a lens which allows a full view of the module and inflated cushion. b. Set up lights in a manner that provides suffi- cient lig
22、hting for all camera views. c. Set up strobe light to illuminate Module, to show T = 0 on all high speed cameras or vid- eos. d. Document test date, sample number and serial number. Attach ID label to front and side of the test fixture/seat or roof rail. e. Take still photographs of Module before te
