What are the implications of a National Technical Approval for me?
Primarily a National Technical Approval refers to products with monitored properties that have been approved by the DIBt German Institute for Civil Engineering. This in turn implies maximum quality and planning certainty.
National Technical Approvals are granted for construction products and types of construction on the basis of the German building codes which are not regulated by generally accepted technical regulations or German standards or which deviate from these to a major extent. They provide reliable verification of applicability of construction products and types of construction in terms of the technical requirements made of building structures.
According to the DIBt website:
What is a National Technical Approval?
A National Technical Approval is granted as verification of applicability for a construction product or type of construction pursuant to the building laws of the Laender of the Federal Republic of Germany which are not regulated by German standards or regulations (Sections 18 (1) and 21 (1) Model Building Code [MBO]).
Construction products and types of construction can be used when the following applies to their use:
- the building structures are in a correct state of maintenance
- the building structures fulfil the requirements of the Laender building codes and are suitably usable during a period of time which is appropriate to the intended purpose (Section 3 (2) MBO).
These requirements include above all
- Structural stability
- Protection from harmful influences
- Protection of human health and of the natural resources
- Fire safety
- Heat protection, protection from noise and vibrations
- Public safety.
Building structures are to be planned, constructed, modified and maintained so as not to pose any hazard to public safety and order, particularly to human life and health and to the natural resources (Section 3 (1) MBO).
"Not regulated" means that
there are no generally accepted technical regulations or technical construction regulations (technical regulations for the planning, rating and construction of building structures and their components) for a construction product (Section 17 (3) MBO) or that while there are published technical regulations for a construction product in construction regulation list A, the construction product deviates in a material respect from these technical regulations in construction regulation list A (Section 17 (3) MBO); or that there are no generally accepted technical regulations for a type of construction or not for all requirements (Section 21 (1) MBO) or that while technical construction regulations have been introduced for a type of construction by the supreme building inspectorate, the type of construction deviates in a material respect from the technical construction regulations (Section 21 (1) MBO).
