Sanitary appliances

Sanitary appliances refer to those parts of a sanitary installation through which accumulating rainwater, foul or waste water is fed into the property drainage system (e.g. WCs, urinals, showers, baths, sinks etc.).

Regulatory framework

In this work area, DIBt grants:

  • national technical approvals (abZ) for sanitary appliances that are not covered by a harmonised standard or European Technical Assessment and which significantly deviate from the Technical Building Rules (cf. MVV TB, Section C 2.12);
  • general construction technique permits (aBG) for construction techniques comprising sanitary appliances.

European Technical Assessments (ETAs) can also be issued for sanitary appliances that are not (fully) covered by a harmonised standard.

National technical approvals and general construction technique permits can be granted together in a single decision ('combined decision'). For sanitary appliances that are covered by a European Technical Assessment, a general construction technique permit for the application may be pertinent.

Technical rules for sanitary appliances have been referenced in the MVV TB:

  • Section B 2.2.6 'Property drainage systems' and
  • Section C 2.12 'Construction products for property drainage'.

For the use of sanitary appliances, the following technical rules are also relevant:

  • DIN EN 12056 (series) – Gravity drainage systems inside buildings
  • DIN 1986-100 – Drainage systems on private ground – Part 100: Specifications in relation to DIN EN 752 and DIN EN 12056
  • DIN 4102-1 – Fire behaviour of building materials and building components – Part 1: Building materials; concepts, requirements and tests
  • DIN EN 13501-1 – Fire classification of construction products and building elements – Part 1: Classification using data from reaction to fire tests

Tests and verifications for sanitary appliances and the corresponding construction techniques that significantly deviate from the applicable technical rules should be carried out based on test plans prepared by DIBt on an application-specific basis.

National procedure

To prepare an abZ/aBG for your construction product, we need an application from you. We recommend that you contact us prior to doing so. Feel free to send us your enquiry informally via email to dibt(at)dibt(.)de or to the competent technical contact listed in the top right.

For a first assessment, please send us the following information:

  • Description of the construction product and its intended field of use
    • e.g. material, configuration, number of sizes, variants, dimensions
    • e.g. use in walls, ceilings, interior construction, building services
  • Description of the construction technique and its field of application
    • e.g. design of walls, ceilings, elements, etc., and interaction of components
    • e.g. application in foundation engineering, reinforced concrete construction, building insulation; as load-bearing or non-load-bearing component; under static and quasi-static loading; fire exposure; other environmental exposures
  • Information regarding impact on regulatory concerns
    • in particular structural integrity, fire protection, health and environment protection, sound insulation as well as thermal performance
  • Explanation of need for an abZ/aBG
  • Contact details
    • preferably email address and/or telephone number, as well as name, organisation/company, and postal address

We will then contact you to clarify the next steps.

If you already hold a DIBt approval and/or construction technique permit and wish to apply for an amendment, supplement, or renewal, please use the form provided 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.
