National approval or market scheme
DIBt Approval / ETA for firestopping systems
National technical approvals, general construction technique permits and European Technical Assessments for construction products and systems, including fire-protection applications.
Where it matters
Where DIBt Approval / ETA applies
Important where German building control requires an abZ, aBG or other DIBt document, or where an ETA is the selected European assessment route.

Certification coverage
How to interpret this certification
Each certificate covers specific products and uses. These details explain what is covered.
Understanding the mark
What the mark or label means
DIBt issues documents such as an abZ, aBG or ETA; there is no single DIBt sticker that proves every construction use. The approval number and complete document are the key evidence.
Fire safety products often covered
- Firestopping systems
- Fire-resistant doors and shutters
- Smoke-control construction systems
- Fire-protective boards and coatings
- Non-standard building products and techniques
Points to check before you buy
- 01
An abZ covers a construction product, while an aBG covers a construction technique. Some solutions need both or a combined document.
- 02
An ETA is a European Technical Assessment and is not the same as a German national approval.
- 03
Check the approved construction, substrates, dimensions, installation instructions and validity.
Before you buy
What to check before relying on this certification
Certification is normally limited to a named model, configuration, standard and use. These checks turn a marketing claim into a procurement record.
- 01
Find out whether local law, your insurer or your project specification requires this approval, or whether it is optional.
- 02
Verify the exact product, standard, certificate holder and current public-register status.
- 03
Check local language, importer, installation, inspection and authority requirements.
- 04
Do not substitute a similar international certificate without written acceptance from the authority or specifier.

Frequently Asked Questions
What is the difference between abZ and aBG?
An abZ is a national technical approval for a product. An aBG is a general construction technique permit for how a system is designed or installed.
Does an ETA automatically satisfy German installation rules?
Not always. The project may also need national construction-technique approval or other German evidence.
Does DIBt Approval / ETA apply to every product made by a certified brand?
No. It normally applies only to the models, variants, uses and conditions named in the current certificate or listing.
What should I include in a purchase order?
State the exact model, required certification and standard, destination market, documents to be supplied and any system compatibility or witnessing requirements.
