Fire resistance tests for service installations - Part 10: Smoke control dampers

This document specifies test methods for smoke control dampers to assess their performance under elevated temperature or fire conditions.
It is of note that the smoke control damper to be tested could require testing to EN 1366 2 and that this is for consideration before carrying out these tests.
Smoke control damper tests are used to confirm that the furnace testing requirements of EN 12101 8 are met and EN 12101 8 is for consideration before carrying out these tests.
Smoke control dampers tested to this document are expected to be classified using EN 13501 4 and this document is expected to be considered before carrying out these tests.
To this end, this document is expected to be read in conjunction with EN 12101 8, EN 13501 4, EN 1366 2 and EN 1363 1, the latter giving further details for fire resistance testing.
For installation details, the requirements for smoke extraction ducts are for consideration and these are defined in EN 1366 8 and EN 1366 9.

Feuerwiderstandsprüfungen für Installationen - Teil 10: Entrauchungsklappen

Dieses Dokument legt Prüfverfahren für Entrauchungsklappen zur Beurteilung ihrer Leistung bei erhöhten Temperaturen oder unter Brandbedingungen fest.
Es sollte beachtet werden, dass für die zu prüfende Entrauchungsklappe eine Prüfung nach EN 1366 2 gefordert sein kann. Dies ist vor der Durchführung dieser Prüfungen zu berücksichtigen.
Prüfungen an Entrauchungsklappen werden durchgeführt, um zu beurteilen, ob die Brandschutzanforderungen nach EN 12101 8 erfüllt werden. EN 12101 8 ist vor der Durchführung dieser Prüfungen zu berücksichtigen
Es wird davon ausgegangen, dass Entrauchungsklappen, die nach diesem Dokument geprüft wurden, nach EN 13501 4 klassifiziert werden. Dieses Dokument ist vor der Durchführung dieser Prüfungen zu berücksichtigen.
Dieses Dokument soll im zusammen mit EN 12101 8, EN 13501 4, EN 1366 2 und EN 1363 1 gelesen werden, wobei die letztgenannte Norm weitere Einzelheiten zur Prüfung des Feuerwiderstands angibt.
Einzelheiten zum Einbau von Entrauchungsleitungen, die zu berücksichtigen sind, sind in EN 1366 8 und EN 1366 9 festgelegt.

Essais de résistance au feu des installations techniques - Partie 10 : Volets de désenfumage

Le présent document spécifie des méthodes d’essai pour évaluer la performance des volets de désenfumage dans des conditions de température élevée ou d’incendie.
Il est à noter que le volet de désenfumage peut nécessiter des essais conformément à l’EN 1366 2 ; cela est à prendre en compte avant de réaliser les présents essais.
Les essais relatifs aux volets de désenfumage sont utilisés pour confirmer que les exigences d’essai de résistance au feu de l’EN 12101 8 sont satisfaites ; dans ce cas, l’EN 12101 8 est à prendre en compte avant de réaliser ces essais.
Il est attendu que les volets de désenfumage soumis aux essais conformément au présent document soient classés conformément à l’EN 13501 4 et que ce document soit pris en compte avant de réaliser les essais.
À cet effet, le présent document est destiné à être lu conjointement avec l’EN 12101 8, l’EN 13501 4, l’EN 1366 2 et l’EN 1363 1, cette dernière donnant des détails supplémentaires sur les essais de résistance au feu.
Pour les détails concernant l’installation, les exigences applicables aux conduits d’extraction de fumées sont à prendre en compte ; elles sont définies dans l’EN 1366 8 et l’EN 1366 9.

Preskusi požarne odpornosti servisnih inštalacij - 10. del: Dimne lopute

Ta dokument določa preskusne metode za dimne lopute za ocenjevanje njihovega delovanja pri povišanih temperaturah ali v požarnih razmerah.
Upoštevati je treba, da bo dimno loputo morda treba preskusiti v skladu s standardom EN 1366-2, kar je treba upoštevati pred izvedbo teh preskusov.
S preskusi dimnih loput se potrjuje, da so zahteve za preskušanje peči iz standarda EN 12101-8 izpolnjene, pred izvajanjem teh preskusov pa je treba upoštevati standard EN 12101-8.
Pričakuje se, da bodo dimne lopute, preskušene v skladu s tem dokumentom, razvrščene v skladu s standardom EN 13501-4 in da bo pred izvajanjem teh preskusov upoštevan ta dokument.
V ta namen se pričakuje, da se bo ta dokument bral skupaj s standardi EN 12101-8, EN 13501-4, EN 1366-2 in EN 1363-1, pri čemer zadnji podaja dodatne podrobnosti glede preskušanja požarne odpornosti.
Pri podrobnostih glede namestitve je treba upoštevati zahteve za kanale za odvod dima, ki so določene v standardih EN 1366-8 in EN 1366-9.
