Fire-resistant mobile partitions

Fire-resistant mobile partitions are multi-part systems, consisting of mobile elements and connections to the adjoining components, which meet the requirements for fire-resistant, non-load-bearing, separating internal walls or partitions.

When closed and locked, fire-resistant mobile partitions prevent the spread of fire and smoke for the duration specified in the building regulations.

Regulatory framework

There are no conclusive technical rules for fire-resistant mobile partitions.

DIBt grants national technical approvals (abZ)/general construction technique permits (aBG) for non-regulated construction products and their application as part of the construction technique.

Fire behaviour is tested in accordance with DIN 4102-2 or DIN EN 1364-1 in conjunction with DIN EN 1363-1. Stability needs to be tested applying DIN 4103-1 accordingly.

Mobile partitions which are not subject to fire-resistance requirements are covered by MVV TB, D 2.2.2.19 (MVV TB, Part D 'Construction products not requiring any verification of fitness for use').

Application forms

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
