in the barrier but without pre-crushing.

              2.6. Traceability

              2.6.1. Impactors shall carry consecutive serial numbers which are stamped, etched or otherwise permanently attached, from which the batches for the individual blocks and the date of manufacture can be established

              2.7. Impactor attachment

              2.7.1. The fitting on the trolley must be according to Figure 8. The fitting will use six M8 bolts, and nothing shall be larger than the dimensions of the barrier in front of the wheels of the trolley. Appropriate spacers must be used between the lower back plate flange and the trolley face to avoid bowing of the back plate when the attachment bolts are tightened.

       3.  Ventilation system

              3.1. The interface between the trolley and the ventilation system should be solid, rigid and flat. The ventilation device is part of the trolley and not of the impactor as supplied by the manufacturer. Geometrical characteristics of the ventilation device shall be according to Figure 9.

              3.2. Ventilation device mounting procedure.

              3.2.1. Mount the ventilation device to the front plate of the trolley;

              3.2.2. Ensure that a 0.5 mm thick gauge cannot be inserted between the ventilation device and the trolley face at any point. If there is a gap greater than 0.5 mm, the ventilation frame will need to be replaced or adjusted to fit without a gap
              of > 0.5 mm.

              3.2.3. Dismount the ventilation device from the front of the trolley;

              3.2.4. Fix a 1.0 mm thick layer of cork to the front face of the trolley;

              3.2.5. Re-mount the ventilation device to the front of the trolley and tighten to exclude air gaps.

              4. Conformity of production

               The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements:

              4.1. The manufacturer shall be responsible for the conformity of production procedures and for that purpose must in particular:

              4.1.1. Ensure the existence of effective procedures so that the quality of the products can be inspected;

              4.1.2. Have access to the testing equipment needed to inspect the conformity of each product;

              4.1.3. Ensure that the test results are recorded and that the documents remain available for a time period of 10 years after the tests;

              4.1.4. Demonstrate that the samples tested are a reliable measure of the performance of the batch (examples of sampling methods according to batch production are given below).

              4.1.5. Analyse results of tests in order to verify and ensure the stability of the barrier characteristics, making allowance for variations of an industrial production, such as temperature, raw materials quality, time of immersion in chemical, chemical concentration, neutralisation etc., and the control of the processed material in order to remove any residue from the
