2.2. Minimum conditions for the control of conformity of Enhanced Child Restraint Systems of categories "Universal", "Semi Universal" and "Restricted", in relation to the dynamic tests according to paragraph 1.6. above. In accordance with the relevant authorities, the holder of an approval will supervise the control of conformity following the method of batch control (para. 2.2.1. below) or following the method of continuous control (para. 2.2.2. below).

2.2.1.4. In order to be accepted, a batch of Enhanced Child Restraint Systems shall satisfy the following conditions. Table 1 MH means harder configuration (the least good results obtained in approval or extension of approval) LH signifies a less hard configuration. This dual sampling plan functions as follows: For a normal control, if the first sample does not contain any defective units the batch is accepted without testing a second sample. If it contains two defective units the batch is rejected. Finally, if it contains one defective unit a second sample is extracted and it is the cumulative number, which shall satisfy the condition of column 5 of the table above. There is a change from normal control to strengthened control if, out of 5 consecutive batches, two are rejected. Normal control is resumed if 5 consecutive batches are accepted. If any batch is rejected, the production is considered to be non-conforming and the batch shall not be released. If two consecutive batches subjected to the strengthened control are rejected, the provisions of paragraph 13. of this Regulation are appl...
Test frequency and results. 2.1. The frequency of testing to the requirements of paragraphs 1.1. to 1.5. of this annex shall be on a statistically controlled and random basis in accordance with one of the regular quality assurance procedures.
2.1.1. Furthermore, in the case of emergency locking retractors, all assemblies shall be checked:
2.1.1.1. Either according to the provisions set out in paragraphs 7.6.2.1. and 7.6.2.2. of this Regulation, in the most unfavourable direction as specified in paragraph 7.6.
2.1.2. Test results shall meet the requirements of paragraphs 6.2.5.3.1.1. and 6.2.5.3.3.
