Common use of Certification of Test Bench Cushion Clause in Contracts

Certification of Test Bench Cushion. The test bench seat cushion shall be certified when new to establish initial values for impact penetration and peak deceleration, and then after every 50 dynamic tests or at least every month, whichever is the sooner, or before each test if the test rig is used frequently. 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, 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 device vertically on a flat rigid surface. Lower the impact mass until it contacts the surface and set the penetration marker to the zero position. Place the device vertically above the test point, raise the mass 500 ± 5 mm and allow it to fall freely to make impact on the test bench seat cushion surface. Record the penetration and the deceleration curve. The peak values recorded shall not deviate by more than 15 per cent from the initial values. Registration of dynamic behaviour In order to determine the behaviour of the dummy and its displacements, all dynamic tests shall be registered according to the following conditions: Filming and recording conditions: The frequency shall be at least 1,000 frames per second; The test shall be recorded on video or digital data carrier over at least the first 300 ms. Estimation of uncertainty: Testing laboratories shall have and shall apply procedures for estimating uncertainty of measurement of the displacement of the dummy’s head. The uncertainty shall be within + 25 mm. Examples of international standards of such procedure are EA-4/02 of the European Accreditation Organization or ISO 5725:1994 or the General Uncertainty Measurement (GUM) method. The measuring procedures shall correspond to those defined in the latest version of ISO 6487. The channel frequency class shall be: Table 9 Type of measurement CFC(FH) Cut-off frequency (FN) Trolley acceleration 600 see ISO 6487Annex A Belt loads 600 see ISO 6487Annex A Chest acceleration 180600 see ISO 6487Annex A Head acceleration 1,000 1,650 Hz Upper neck force 1000600 Upper neck moment 600 Chest deflection 600 Abdominal pressure 180 The sampling rate should be a minimum of 10 times the channel frequency class (i.e. in installations with channel frequency class of 1 000, this corresponds to a minimum sampling rate of 10,000 samples per second per channel). Test reports of type approval and of production qualification The test report shall record the results of all tests and measurements including the following test data: The type of device used for the test (acceleration or deceleration device); The total velocity change; The trolley speed immediately before impact only for deceleration sleds; The acceleration or deceleration curve during all the velocity change of the trolley and at least 300 ms; The time (in ms) when the head of the dummy reaches its maximum displacement during the performance of the dynamic test; The place occupied by the buckle during the tests, if it can be varied; Any failure or breakage; The following dummy criteria: HIC, Head Acceleration 3 ms, Upper Neck Tension Force, Upper Neck Moment, Thorax Chest Deflection; Abdominal Presssure (in frontal impact) and and Adult Seat belt bench installation forces. The lap belt force. If provisions relating to anchorages contained in Annex 6, Appendix 3, to this Regulation have not been respected, the test report shall describe how the child restraint is installed and shall specify important angles and dimensions. When the child restraint is tested in a vehicle or vehicle structure, the test report shall specify the manner of attaching the vehicle structure to the trolley, the position of the Enhanced Child Restraint System and vehicle seat and the inclination of the vehicle seat-back. The test reports of type approval and of production qualification shall record the verification of markings and of instructions on installation and use. Production qualification In order to make sure that the manufacturer's production system is satisfactory, the Technical Service, which conducted the type approval tests, shall carry out tests to qualify production in accordance with paragraph 9.2. below. Qualifying the production of Enhanced Child Restraint Systems The production of each new approved type of Enhanced Cchild Rrestraint Ssystem of categories i-Size and specific to vehicle shall be subjected to production qualification tests. Additional qualifications of production may be prescribed following paragraph 11.41.3. For this purpose, a random sample of 5 Enhanced Child Restraint Systems will be taken from the first production batch. The first production batch is considered to be the production of the first block containing a minimum of 50 Enhanced Child Restraint Systems and a maximum of 5,000 Enhanced Child Restraint Systems. Dynamic tests for frontal and rear impact

Certification of Test Bench Cushion. The test bench seat cushion shall be certified when new to establish initial values for impact penetration and peak deceleration, and then after every 50 dynamic tests or at least every month, whichever is the sooner, or before each test if the test rig is used frequently. 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 teststests on the seat 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 device seat cushiondevice vertically on a flat rigid surface. Lower the impact mass until it contacts the surface and set the penetration marker to the zero position. Place the device vertically above the test point, raise the mass xxxxxx a height of 500 ± 5 mm and allow it to fall freely to make impact on the test bench seat cushion surface. Record the penetration and the deceleration curve. 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.
