Mandatory systems

A multitude of new processes and product developments in the field of construction technology deviate considerably from generally recognised technical rules or belong to the group of "unregulated construction products". These construction products or types of construction require either a "allgemeine bauaufsichtliche Zulassung" (abZ, general building approval) or approval in individual cases, a "allgemeines baufaufsichtliches Prüfzeugnis" (abP, general building test certificate) or a European Technical Assessment (ETA).

The certification body of FIW München is notified according to the European Construction Products Regulation (CPR) by the "Deutsches Institut für Bautechnik DIBt (German Institute for Construction Technology). One of the prerequisites for this is accreditation by the Deutsche Akkreditierungsstelle GmbH (DAkkS).
For European standardised construction products, the "systems for assessment and verification of reliability of constance" are regulated in Annex V of the CPR. Thermal insulation materials are initially always assigned to System 3, in which certification is not stipulated. Some of the properties of thermal insulation materials fall into System 1 for the assessment and verification of constancy of performance due to their classification under Basic Work Requirements (BWR) 1 or 2 pursuant to Annex I of the Construction Products Regulation. In System 1, the notified certification body carries out product sampling for initial testing, an initial inspection and periodic auditing of factory production control (FPC). Regular sampling and testing of their properties is also not stipulated in System 1. Certification pursuant to the CPR is limited to the properties that are governed by System 1. For thermal insulation materials, this is often the case concerning Reaction to fire behaviour in classes C, B and A, if the production process influences the Reaction to fire behaviour. In such cases, the "Certificate of Constance of Performance" only indicates the Reaction to fire behaviour. This means that the thermal conductivity of an insulation material is generally not certified pursuant to the CPR and is declared solely by the manufacturer. In the declaration of performance (DoP), the manufacturer declares the properties of their construction product independently and in a legally binding manner and names any certification body that may have been involved as well as the notified testing body that carried out the required initial test. By using the CE mark, the manufacturer establishes the conformity of the construction product with a European Product Standard or European Technical Assessment (ETA) and refers to its Declaration of Performance.

The certification body of FIW München is recognised by the building inspectorate as an approved certification body in accordance with the German "Landesbauordnung" (LBO, State Building Code). FIW München is listed in the Directory of PÜZ Bodies of the "Deutsches Institut für Bautechnik" (DIBt, German Institute for Building Technology) for a large number of building products - mainly insulation materials. Construction products covered by a harmonised European standard (hEN) or a European Technical Assessment (ETA or ETB) may not be regulated in parallel by the member states. Furthermore, the European standards and assessments are considered to be complete, which means that no additional national requirements need to be imposed on these construction products (see ECJ ruling C-100/13 of 16.10.2014). This means that general building inspectorate approvals (abZ) can now only be issued by DIBt for insulation materials for which there is no hEN or this has not yet been published in the OJEU (Official Journal of the European Union) and for which an applicant has not yet applied for an ETA.
Allgemeine baufaufsichtliche Zulassungsen (abZ, General building inspectorate approvals) define the properties of the building product, regulate its use and require internal control by the manufacturer and external monitoring by a recognised surveilance body with complete product testing twice a year. A certification body approved by the building inspectorate verifies the conformity of the requirements according to abZ with the test and audit results of the testing and inspection body and issues a certificate of conformity. The manufacturer then marks the approved product with the "Ü-symbol" in line with the "Übereinstimmungszeichenverordnung" (ÜZVO, Ordinance on the Mark of Conformity).
