− Date of manufacture and date of inspection of the building product or the raw material or its
components;
− Results of the checks and inspections and comparison with the requirements,
− Signature of the person responsible for the factory production control.
(4) Reports must be retained for a period of at least five years and presented to the inspection
body appointed for the purposes of performing external inspections. They are to be submitted to
the Deutsches Institut für Bautechnik and the highest competent building authority upon request.
(5) Where the results of inspections are unsatisfactory, the manufacturer must immediately take
the necessary steps in order to rectify the defect. Building products that do not meet the
requirements are to be handled in such a way that they cannot be mistaken for compliant products.
Once the defect has been rectified, the inspection in question must be repeated without delay, in
so far as is technically feasible.
2.4.3
External inspection
(1) In every manufacturing plant, the plant and the factory production control must undergo regular
checks in the form of an external inspection, at least twice per year.
(2) An initial inspection of the containers must be carried out as part of the external inspection.
The tests specified in Section 2.4.2 must be carried out, as a minimum, during an external
inspection and initial inspection. In addition, samples may be taken for the purposes of spot
