Construction products for sealing openings for electrical services in fire-resistant components

Electrical service closures seal openings for electrical installations in fire-resistant components inside a building or structural work (e.g. in partitions, service ducts, suspended ceilings, timber frame or timber beam ceilings). They prevent the spread of fire and smoke through the sealed opening, thus ensuring that the components continue to meet the requirements corresponding to their fire-resistance class.

Electrical service closures mainly consist of construction products for sealing the opening, fasteners and, where required, accessories.

Depending on the product(s) used, construction products for sealing openings for electrical services may be installed on one or both sides of the separating component, directly opposite or offset, without additional measures being required.

Regulatory framework

DIBt grants national technical approvals (abZ)/general construction technique permits (aBG) for electrical service closures.

Required verifications:

  • resistance to fire in accordance with DIN 4102-2 or DIN EN 1364-1.

Please contact DIBt before carrying out verifications for extended applications (EXAP) which are not already covered by the verifications named above.

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).

Please feel free to use the template below.

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.
