Confirmation of conformity for each manufacturing plant must be provided through a declaration of conformity by the manufacturer, based on factory production control and a conformity certificate from an accredited certification body, along with regular third-party monitoring by an accredited inspection body.
Factory Production Control
Each manufacturing plant must implement and conduct factory production control. This involves continuous monitoring by the manufacturer to ensure products comply with this approval and Document A³.
Factory production control must include:
- Description and verification of raw materials and components.
- Control and tests during manufacturing.
- Verification and tests on the finished product.
Each fire protection closure must be checked for conformity with this approval and Documents A³ and B³⁴. For automated production lines, this check must be performed at least once per production day, in coordination with the inspection body.
Results of factory production control must be recorded, including:
- Product or material designation.
- Type of control or test.
- Date of manufacture and testing.
- Results of controls and tests, compared against requirements.
- Signature of the person responsible for factory production control.
Records must be kept for at least five years and submitted to the inspection body.
In case of insufficient test results, the manufacturer must take immediate corrective action. Non-conforming products must be handled to prevent mix-ups. After correction, the relevant test must be repeated if technically possible and necessary to prove the correction.
Third-Party Monitoring
The factory and its production control must be regularly monitored, at least twice annually, by an accredited inspection body.
The initial inspection must verify compliance with Sections 1.1, 2.1, and Document A³. It must also confirm the presence and compliance of installation instructions (Section 2.2.3) with Document B³⁴ and Section 2.2.3.
During third-party monitoring, it must also be verified that components used for the fire protection closure have the required conformity proof.
This does not apply to components like accessories and fire protection insulation whose usability was regulated within the approval process for this closure. These must be checked during the manufacturing monitoring of the fire protection closures at each plant. Their construction and properties must correspond to the products used in the approval tests.
Certification and third-party monitoring results must be kept for at least five years and submitted to the Deutsches Institut für Bautechnik and the responsible building supervisory authority upon request.
