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 cornières 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
cornières métalliques destinés à l�application d�enduits extérieurs.
La présente norme traite des lattis métalliques destinés à permettre la fixation à des structures ou à 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 systèmes d�enduits de protection contre l�incendie.
La présente Norme européenne traite des cornières métalliques destinées à être utilisées pour améliorer la
protection des angles extérieurs et à obtenir les caractéristiques des finitions extérieures de la construction
ainsi que les cornières métalliques destinées à être utilisées en tant que cornières de mouvement ou
d�expansion. Les cornières contribuent également à la protection contre l�incendie.

Overview

EN 13658-2:2005 - published by CEN - is the European standard that defines metal lath and beads for external rendering. It specifies definitions, material and dimensional requirements, and test methods for products used to provide a key for plaster, protect external angles, form stop and drip profiles, act as movement/expansion features and contribute to fire protection of rendered façades. This Part 2 standard complements Part 1 (internal plastering) and supports CE marking and conformity under the EU Construction Products framework.

Key topics and requirements

• Scope and product types: Covers a wide range of metal lath (expanded flat, corrugated, ribbed, paperbacked wire, welded mesh, stainless claylath) and metal beads (angle beads, stop beads, plastered socle beads, movement/corner movement beads).
• Materials and corrosion resistance: Requirements for base metals and coatings (stainless steels, aluminium, zinc/alloys, organic coatings) to ensure durability for external exposure.
• Fire behaviour: Addresses both reaction to fire and fire resistance characteristics relevant to rendered systems and references fire test standards and classifications.
• Dimensional and physical tests: Sampling and measurement methods for thickness/diameter, length, width, straightness, profile dimensions and coating thickness.
• Functional features: Definitions and performance expectations for beads used as edge protection, control joints and movement joints (movement capability example: ±1.5 mm range specified for flexible connectors).
• Conformity & quality control: Type testing, initial and further type testing, and Factory Production Control (FPC) requirements covering personnel, equipment, raw materials, product testing, traceability, marking, handling non-conformances and corrective action.
• Marking and CE: Guidance on product designation, marking, labelling, packaging and Annex ZA explaining relationship to the EU Construction Products Directive and CE marking procedures.

Applications and users

• Applications: External render systems, fire-protecting plastering systems, façade detailing (corners, reveals, stops, socle/drip details), movement joints and repair/retrofitting of rendered façades.
• Who uses this standard:
  • Manufacturers of metal lath and render beads
  • Façade contractors and plasterers specifying components for external rendering
  • Specifiers, architects and engineers ensuring compliance and fire performance
  • Testing and certification bodies performing type tests and FPC audits
  • Distributors and clients requiring CE-marked building products

Related standards

• EN 13658-1 (Internal plastering)
• EN 13914-1 (Design and application of external rendering)
• Fire test standards (EN 13501‑1/2, EN 1364‑1, EN 1365 series)
• Material standards referenced for metals and coatings (e.g., EN 10088, EN 10327)
