Each specimen can have different size, geometry, density, etc. which impacts ramp times; therefore, each transition period will vary in length of time. Total test time should exceed 38 hrs due to time required to transition from level

29、to level. The sag test is to be conducted at the prototype stage using a fixture representing the vehicle fixing points.

30、WSS-M15P27-F maintained, but the method of achieving the check points is as follows: The check points will be achieved by drilling 6mm diameter holes in the headliner above the H points for depth micrometer measurements. The five points across the front and rear obscuration bands are noted by tape m

31、arkers attached to the front and a rear screen, an example is shown in the diagram. During the full vehicle test, the air vents are to be set to open and the windows are to be open. Check point locations are marked at the following locations on the test headliner: Front Edge along the windscreen obs

32、curation line, five points on one line beginning at the center point and spaced at approximately 220mm to the left and right of the center. Rear Edge along the rear screen line, with check points as above. Five checkpoint locations are also to be marked directly above the headform center points. The

33、 head form center points are to be determined from the H points on the vehicle layout drawing, shown on the diagram below. Moonroof/Sunroof eight checkpoint locations are to be determined according to the attached sketch. Test Criteria Depth measurements for each checkpoint location are to be noted

34、prior to and at the end of the environmental cycle. The test criterion is to be applied 24 hours after completion of the sag test.
