Certification of Test Bench Cushion. 7.3.1. The test bench seat cushion shall be certified when new to establish initial values for impact peak deceleration, and then after every 50 dynamic tests or at least every month, whichever is the sooner. 7.3.2. The certification and measuring procedures shall correspond to those specified in the latest version of ISO 6487; the measuring equipment shall correspond to the specification of a data channel with a channel filter class (CFC) 60. Using the test device defined in Annex 14 to this Regulation, conducts 3 tests on the bench base prepared as described in Annex 6, foam covered with textile, 150 ± 5 mm from the front edge of the cushion on the centre line and at 150 ± 5 mm in each direction from the centre line. Place the bench cushion on a flat rigid surface. Place the device vertically above the test point, at a height of 500 ± 5 mm and allow it to fall freely to make impact on the seat surface. Record the deceleration curve. 7.3.3. The initial peak recorded values for impact deceleration shall be 24 ± 4 g and subsequent peak values recorded shall not deviate by more than 15 per cent from the initial values.
