Ablation coatings

Ablation coatings are fire-stopping and fire-sealing products which are activated when exposed to high temperatures due to their chemical compositions. Chemical and/or physical reactions are triggered in which energy and/or material is consumed.  In contrast to the intumescent building materials, they do not expand or expand only slightly.

Regulatory framework

Ablation coatings are safety-relevant non-regulated products, cf. Model Building Code (MBO), Section 14, 26 and 17(3).

DIBt grants national technical approvals (abZ) for these products, verifying their fitness for use as fire-stopping and fire-sealing products.

DIBt also issues European Technical Assessments (ETAs) for fire-stopping and fire-sealing products in which ablation coating significantly contributes to the fire-protective effect, such as cable and pipe penetration seals or fire-resistant joint systems.

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.
