Paragraph 42 Statistical verification of conformityF1

A manufacturer must take all measures necessary so that the manufacturing process and its monitoring ensure the homogeneity of each lot produced, and must present the manufacturer's explosives for verification in the form of homogeneous lots.

The approved body must take a random sample from each lot; all explosives in a sample must be individually examined and appropriate tests set out in the relevant designated standards, or equivalent tests set out in other relevant technical specifications, must be carried out in order to verify their conformity with the approved type described in the Type examination certificate and with the applicable requirements of these Regulations and to determine whether the lot is accepted or rejected; in the absence of such a designated standard, the approved body concerned must decide on the appropriate tests to be carried out.

If a lot is accepted, all explosives of the lot must be considered approved, except for those explosives from the sample that have been found not to satisfy the tests.

The approved body must issue a certificate of conformity in respect of the examinations and tests carried out, and must affix its identification number to each approved explosive or have it affixed under its responsibility.

A manufacturer must keep the certificates of conformity at the disposal of the relevant authorities for 10 years beginning on the day on which the explosive has been placed on the market.

If a lot is rejected, the approved body, or enforcing authority, must take appropriate measures to prevent the placing on the market of that lot and, in the event of the frequent rejection of lots the approved body may suspend statistical verification and take appropriate measures.
