Certificate of conformity
2.4.1 General
(1)
The certification that the containers conform to the provisions of this National Technical
Approval must be carried out for each manufacturing site by means of a certificate of
conformity based on internal factory production monitoring, as well as external monitoring on a
regular basis, including an initial inspection of the containers pursuant to the following
provisions.
(2)
To obtain the certificate of conformity and the external monitoring, as well as the
associated product inspections, the manufacturer of the containers must make arrangements
with a certification agency recognised for this purpose, as well as a monitoring agency
recognised for this purpose.
(3)
The manufacturer must mark the constructed products with the conformity mark,
specifying their use, as a declaration that a certificate of conformity has been issued.
(4)
A copy of the certificate of conformity granted by the certification agency must be
submitted to the Deutsches Institut für Bautechnik.
A copy of the initial inspection report must also be given to the DIBt.
(5)
The professional installers instructed by the applicant and/or the manufacturer with their
own professional staff must issue the confirmation that the containers conform to the
provisions of this National Technical Approval in their installed state with a declaration of
conformity based on the installation/assembly instructions of the applicant.
2.4.2
In-house production monitoring
(1)
In-house production monitoring must be set up and carried out in each production
factory. In-house factory production monitoring means the continuous monitoring of production
by the manufacturer with the aim of ensuring that the containers produced by the manufacturer
conform to the provisions of this National Technical Approval.
(2)
The in-house factory production monitoring must include at least the inspections listed
in Annex 4, Section 1.
(3)
The results of in-house factory production monitoring must be recorded and evaluated.
The records must contain at least the following data:

Designation of the product and/or the starting material;
-
Type of monitoring or inspection;
-
Date of manufacture and inspection of the product and/or starting material or its
components;
-
Result of monitoring and inspections and comparison with requirements:
-
Signature of the person in charge of in-house factory production monitoring

Z-40.21-365
(4)
The records must be preserved for at least five years and submitted to the external
monitoring agency. They must be submitted to the Deutsches Institut für Bautechnik and to the
most senior competent building monitoring agency if requested.
(5)
In the event of unsatisfactory inspection results, the manufacturer must immediately
take the necessary measures to correct the defect. Products that do not meet the requirements
must be handled so that they cannot be confused with compliant products. After the defect has
been corrected, the inspection in question must be immediately repeated, to the extent
technically possible.
2.4.3 External monitoring
(1)
The in-house production monitoring in each production factory must be verified by an
external body in accordance with Annex 4, Section 2 (2) on a regular basis, however at least
twice annually.
(2)
An initial inspection of the containers pursuant to Annex 4, Section 2 (1) must be
performed as part of the external monitoring. Moreover, samples can be taken for random
sample tests. Taking samples and performing inspections are the responsibility of the
recognised monitoring agency. If the usability inspections on which the National Technical
Approval is based are carried out using samples officially taken from ongoing production,
these inspections replace the initial inspection.
(3)
The results of the certification and external monitoring must be retained for at least five
years. They must be submitted by the certification agency and/or monitoring agency to the
Deutsches Institut für Bautechnik and to the most senior competent building monitoring
agency, if requested.
