17、window and lock systems, including, but not limited to: glass and glass guidance components, window regulator and attaching hardware, all seals, applicable interior and exterior trim, door key and key cylinder, and door latch, handle and lock rods. For the most realistic theft evaluation, a vehicle

18、or body is recommended. Also recommended is an evaluation of both manual and power window systems. It is recommended that the door assembly and door components be dimensionally certified before testing is started. Note: Painting the door gloss black over white primer may aid the test engineer in vis

19、ual damage detection (gloss black to highlight panel deformation, white primer to highlight scratching and chipping). 3.4 Test Time. The following is an estimate on the amount of time (work-hours) needed to perform this procedure. Calendar time: 1 day Test hours: 8 hours Coordination hours: 8 hours

20、Note: These time estimates are approximate averages. Actual times vary considerably depending on early component failures (and subsequent availability of replacement parts), testing to varying multiples of cycle lives, varying requirements for frequency of environmental test conditions, scheduling p

21、roblems for test facilities, test equipment malfunctions, scheduling of overtime and/or multiple shifts, scheduling of “witnesses” for tests, actual readiness of test samples upon receipt, unique or additional requests for test details, running multiple samples (times shown are for one system), etc.

22、 These times consider preparation and other downtime, actual test, and analysis of data in capturing a total calendar time. Report writing, approval, processing, etc., are not part of this time. 3.5 Test Required Information. The requesting engineer is responsible for providing specifications approp

23、riate to the particular vehicle line being tested (reference Vehicle Technical Specification (VTS)/Subsystem Technical Specification (SSTS) paragraph numbers if applicable). See 2.3.

30、ar tests, and experience in the use of the referenced test equipment, are critical to achieving the estimated times shown in “3.4 Test Time”. 4 Procedure 4.1 Preparation. 4.1.1 Sample Inspection. The test and requesting engineers should inspect the test items to insure all material listed in 3.3 is

31、of correct design level and assembled properly. Check for cracks, paint chips, dents, etc. Document any variation/deviation in assembly, etc. This is done for post test analysis purposes. 4.1.2 Sample Preparation. This test is normally run on the test subject in an “as received” condition. If it is

32、requested to be run in a specifically adjusted condition, follow the applicable procedure(s). 4.1.2.1 It is recommended that the door be heat cured (per the production paint bake process) to ensure proper strength of the structural adhesives. Install and adjust the window and lock systems per the pr

33、oduction process and torque all fasteners to specified torque values (see 3.5). Do not apply tape to the door glass for safety considerations (to contain glass fragments should shattering occur) when performing the window system theft test. This is because shattering the glass is a failure mode and

34、tape could affect the stiffness of the glass, altering test results. Follow safe operating procedures, including wearing safety glasses and safety gloves, when performing this test. 4.1.2.2 Mark all window system fasteners and attachments to check for movement or rotation during test. 4.1.3 Faciliti

35、es and/or Equipment Preparation. 4.1.3.1 Record the instrumentation calibration information on the attached Data Sheet A1 Instrument Calibration or an equivalent document. 4.1.3.2 As applicable, clamp the door securely to the fixture (i.e., door cart) in approximate body position so the door lock cy

36、linder or the exterior panel surfaces are accessible. 4.2 Conditions. 4.2.1 Environmental Conditions. Unless otherwise specified in this documents text or by the requesting engineer, the typical environmental conditions for this test are the temperature, humidity and pressure at the major test facil

37、ity (3.1). Unless otherwise noted, these conditions are typically 22 +3 C, relative humidity of 40 +20% and atmospheric pressure equivalent to the local barometric (variable during any given day and from day to day).

Note: The trim pad is removed to aid the engineer in determining the best areas to attempt to access for unlocking the door locking system. 4.3.1.1.2 Run the w

42、indow system into its full up, stall position. 4.3.1.1.3 Measure and record the operating efforts of the various lock system handles, levers, etc. Note: It may be necessary to simulate the door striker if testing a door on a door cart or fixture. Using a pen, pencil, or your finger engage the door l

43、atch fork bolt. Operate the outside or inside door handle while pulling inboard on the simulated lock striker. If the latch fork bolt returns to its free position the door was not locked. Note: Record if the Child Security feature is engaged. 4.3.1.1.4 Lock and latch the door. 4.3.1.2 Setup Instruct

44、ions for Door Window System Theft Test. Note: This procedure covers the typical roll up/down window system used in most vehicle doors. Sliding, swing out, etc., window systems will require unique methods of evaluation, reorientation of load directions, etc. Record all methods used. 4.3.1.2.1 Perform

45、 initial Door Window System-Performance Test (GMW15081) for baseline performance characteristics. 4.3.1.2.2 Lower the window, from the full up position, so that the load cell with adapters can contact the top edge of the glass surface, while not contacting the body or door header. 4.3.1.2.3 Install,

46、 adjust, and calibrate the load cell or equivalent, at a specified location (see 3.5.2.1) and connect it to the load/deflection plotting device. 4.3.1.2.4 Install the LVDT in line with, or as close as possible to the load cell. 4.3.1.2.5 Adjust and calibrate the LVDT at a specified location (see 3.5

47、.2.1) and connect it to the load/deflection plotting device. 4.3.1.2.6 Mark a line near the bottom of the window and onto a stationary part of the door or body to provide a visual “zero” reference position. This can be done at both the front and rear edges of the window. While this is not an accurat

48、e measurement of deflection or set, it can indicate if the window is cocking as a result of the loading. 4.3.2 Test Operation Instructions. 4.3.2.1 Test Operation Instructions For Door Lock System Theft Test. 4.3.2.1.1 Insert the “Slim Jim” tool between the glass and outer belt line-sealing strip.
