5 Test methods

Ribbon width and 5.1 Breaking test Two samples taken webbing length not less than 10 times the width of the webbing, and a sample was treated in Appendix A, a sample wherein Test after low-temperature treatment; another sample has high temperature treatment and after water immersion test. One end fixed to the test, is not applied to the other end of the small 2250N in tension, while measuring the width of the webbing; 9000N pulling force continues to increase, maintaining 10s. 5.2 elastic webbing elongation test Taken webbing length not less than 10 times the width of the web samples, one end is fixed, the tension of not less than 2250N is applied to the other end, and measurement Calculating the elastic webbing elongation. 5.3 Metal corrosion test element 5.3.1 Sample Metal corrosion test elements should meet the requirements GB/T 10125-1997 in Chapter 6, and no less than two, placed In the salt spray test chamber, salt spray test conducted 24h. After the test, the treated sample area measurement appearance and corrosion defects. 5.3.2 Corrosion test solution should be consistent with GB/T 10125-1997 in Chapter 3. 5.3.3 corrosion test shall comply with GB/T 10125-1997 in Chapter 4 with a salt spray chamber. 5.4 Test seat belt buckle open Applying a belt (670 ± 45) N of tension in the safety test and the value of the recording power open the buckle. Lateral tensile test was 5.5 As shown, the horizontal lateral direction of the seat, by a block shape (see Appendix B) 1 4500N tension is applied, the force is not time Less than 10s. 5.6 prior to the tensile test 3, the horizontal plane in front of the seat into a front upward direction of 60 ° ± 15 °, by a body block (see Appendix B) is applied 4500N tensile force, force time is not less than 10s, the SIP force should a predetermined point in FIG. 1, SIP position as shown in FIG. Description. 1 --- through points along the SIP; 2 --- horizontal tensile force F1. Lateral tensile tests 1 FIG 2 SIP position FIG 3 Forward tensile test

Appendix A

(Normative) Test Method webbing Pretreatment A.1 low temperature First webbing place at a temperature of 20 ℃ ± 5 ℃, relative humidity of 65% ± 5% of the environment for at least 24h, and then a ribbon 2kg weight collectively stored at low temperature of -30 ℃ ± 5 ℃ the box, after the webbing fold for 1.5 h, and the pressure in the 2kg weight folded At low temperature in the tank to continue to be placed 30min. After 5min the weight was removed, and the width of the ribbon breaking test should be taken out webbing cryostat Measuring. A.2 high temperature treatment The ribbon was placed in a temperature 60 ℃ ± 5 ℃, relative humidity of 65% ± 5% of the high-temperature storage chamber 3h, the webbing width, and breaking test Test measurement should be taken within a 5min after the webbing from the heating chamber. A.3 water immersion test The webbing completely immersed in a temperature of 20 ℃ ± 5 ℃ and wetting agent has been added a small amount of distilled water stored 3h, using any Test applicable to fiber webbing humectants, ribbon width should be measured, and the breaking test webbing within 10min after removal from the solution.
