Construction products detail

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
