Metal lath and beads - Definitions, requirements and test methods - Part 2: External rendering
This European Standard specifies the requirements and test methods of metal lath and beads for external render-ing.
This European Standard covers metal lath intended to be used for fixing to structures or solid backgrounds to pro-vide a key to hold the plaster in position. Used in this way it enables fire protecting plastering systems to be pro-vided.
This European Standard covers metal beads intended to be used to improve the protection of external angles and also provide features to the external finish of the construction and which can also be used as movement or expan-sion beads. They also contribute to fire protection.
Putzträger und Putzprofile aus Metall - Begriffe, Anforderungen und Prüfverfahren - Teil 2: Außenputze
Dieses Dokument legt die Anforderungen an Putzträger und Putzprofile aus Metall für Außenputze und die entsprechenden Prüfverfahren fest.
Dieses Dokument gilt für Putzträger aus Metall, die an Unterkonstruktionen oder festen Untergründen befestigt werden, um einen Putzgrund zu schaffen, der die Haftung des Putzes sicherstellt. Werden sie auf diese Weise verwendet, so ermöglichen sie Putzsysteme, die für den Brandschutz wirksam sind.
Dieses Dokument gilt für Putzprofile aus Metall, die zur Erhöhung des Schutzes äußeren Ecken und als dekorative Putzanschlüsse und Putzabschlüsse verwendet werden, sowie für Putzprofile die als Bewegungsfugen- oder Dehnungsfugenprofile verwendet werden. Putzprofile aus Metall tragen auch zum Brandschutz bei.
Lattis et cornieres métalliques - Définitions, exigences et méthodes d'essai - Partie 2: Enduits extérieurs
La présente Norme européenne définit les exigences et les méthodes d?essai applicables aux lattis et aux
cornieres métalliques destinés a l?application d?enduits extérieurs.
La présente norme traite des lattis métalliques destinés a permettre la fixation a des structures ou a des
supports massifs, afin de fournir un support d?accrochage de l?enduit. Le lattis permet, dans ce type
d?utilisation, la mise en place de systemes d?enduits de protection contre l?incendie.
La présente Norme européenne traite des cornieres métalliques destinées a etre utilisées pour améliorer la
protection des angles extérieurs et a obtenir les caractéristiques des finitions extérieures de la construction
ainsi que les cornieres métalliques destinées a etre utilisées en tant que cornieres de mouvement ou
d?expansion. Les cornieres contribuent également a la protection contre l?incendie.
