This work area concerns single or double-leaf internal pedestrian doorsets (swing doors) with fire resistance and/or smoke control characteristics which are intended for operation by persons. They are either opened manually and always close automatically or are normally kept open but close automatically in case of fire or smoke.

Closures with fire resistance and/or smoke control characteristics are made of

• sheet steels with fire-protective inlays,
• timber and wood-based materials,
• aluminium or steel tubular frame with glazing.

Possible variants for internal doorsets with fire resistance and/or smoke control characteristics include:

• with or without a top part (with or without glazing) contained in a single frame for insertion into a single opening, independent of whether these are installed flush or by means of transoms,
• with or without fire-resistant glazing in the door leaf or leaves,
• with a permanently elastic seal running along three sides as well as in the centre rebate of double-leaf doors (for doors with fire resistance characteristics),
• with a permanently elastic seal running along three sides as well as in the centre rebate of double-leaf doors in combination with a bottom seal (for doors with smoke control characteristics),
• with hardware and accessories.

Regulatory framework

Internal pedestrian doorsets with fire resistance and/or smoke control characteristics are considered to be 'non-regulated construction products'. In Germany, they require verification of fitness for use in the form of a national technical approval (abZ) from DIBt or a project-related approval (ZiE) from the competent state authority. The construction technique (design and execution) requires a general construction technique permit from DIBt (aBG) or a project-related construction technique permit (vBG) from the competent state authority.

National technical approvals/general construction technique permits can also be granted in a combined decision.

European Technical Assessments (ETAs) can also be issued for corresponding products.

For the assignment of the fire classification to regulatory requirements, the relevant provisions of the Technical Building Rules following MVV TB, Annex 4, Section 5 apply.

Further information on national and European procedures as well as tests and documents to be submitted are summarised in the 'Explanations on the approval procedure for closures with fire resistance and/or smoke control properties' (Erläuterungen zum Zulassungsverfahren für Feuerschutzabschlüsse).
