Panel Padding Specification Clause Samples

Panel Padding Specification. 2.1. General The impact surface of the door panel shall be entirely covered with a padding material of 55 mm in thickness (see Figure 1 above). The material shall comply with the performance criteria specified in paragraph 2.3. (Figure 4 below) of this appendix when tested in accordance with paragraph 2.2. of this appendix. A material combination meeting these requirements is described in paragraph 2.4. of this appendix. 2.2. Test procedure for the assessment of panel padding material The test set up consists of a simple drop test using a spherical head form. The spherical head form has a diameter of 150 mm and a mass of 6 kg (±0.1 kg). The impact speed is 4 m/s (±0.1 m/s). The instrumentation should allow the assessment of the time of first contact between the impactor and the sample as well as the head form acceleration at least in direction of impact (Z-direction). The material sample should have the dimensions of 400 x 400 mm The sample should be impacted in its centre. 2.3. Performance criteria for the padding material The time of first contact between sample material and head form (t0) is 0 ms. The impactor acceleration shall not exceed 58 g. Key 1- Upper limit of 58 g 2- Lower limit for the maximum peak at 53 g (11 to 12 ms) 3- Upper limit for the decline of acceleration (15 g at 20,5 ms to 10 g at 21,5 ms) 4- Lower limit for the decline of acceleration (10 g at 20 ms to 7 g at 21 ms) 2.4.
