Metal lath and beads - Definitions, requirements and test methods - Part 1: Internal plastering

This European Standard specifies the requirements and test methods of metal lath and beads for internal plaster-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. Metal lath is used vertically to support linings for walls, partitions and col-umns and horizontally to support linings for ceilings and beams. Used in this way it enables fire protecting plaster-ing systems to be provided.
This European Standard covers metal beads intended to be used to improve the protection of corners and also provide features to the internal finish of the construction as well as metal beads intended to be used as depth gauge beads and movement or expansion beads. They also contribute to fire protection.

Putzträger und Putzprofile aus Metall - Begriffe, Anforderungen und Prüfverfahren - Teil 1: Innenputze

Dieses Dokument legt die Anforderungen an Putzträger und Putzprofile aus Metall für Innenputze 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. Putzträger aus Metall werden vertikal als Putzuntergrund für Wände, Trennwände und Stützen und horizontal als Putzuntergrund für Decken und Balken verwendet. Auf diese Art verwendet, ermöglichen sie die Herstellung von Brandschutz-Putzsystemen.
Dieses Dokument gilt auch für Putzprofile aus Metall, die zur Verbesserung des Eckenschutzes und als dekorative Putzanschlüsse und Putzabschlüsse verwendet werden, sowie für Putzprofile, die als Schnellputzleisten und Bewegungs- oder Dehnungsfugenprofile verwendet werden. Putzprofile aus Metall tragen auch zum Brandschutz bei.

Lattis et cornieres métalliques - Définitions, exigences et méthodes d'essai - Partie 1: Enduits intérieurs

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 intérieurs.
La présente norme s�appliquent aux lattis métalliques destinés à permettre la fixation à des structures ou à des
supports solides, afin de fournir un support d�accrochage de l�enduit. Le lattis s�emploie verticalement comme
support d�enduit des revêtements de murs, de cloisons et de colonnes, et horizontalement comme support d�enduit
des revêtements de plafonds et de poutres. 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 concerne les cornières métalliques destinées à être utilisées pour améliorer la
protection des angles et obtenir les caractéristiques des finitions intérieures de la construction ainsi que les
cornières métalliques destinées à être utilisées en tant qu�indicateurs d�épaisseur, cornières de mouvement ou
d�expansion. Les cornières contribuent également à la protection contre l�incendie.

Overview

EN 13658-1:2005 - "Metal lath and beads - Definitions, requirements and test methods - Part 1: Internal plastering" is a CEN European Standard that specifies definitions, material and dimensional requirements, test methods and conformity procedures for metal lath and metal beads intended for internal plastering. The standard covers products used to provide a mechanical key for plaster, to support linings for walls, partitions, columns, ceilings and beams, and to improve corner protection, finishing details, depth control and movement joints. It also addresses aspects of fire protection and CE marking under the EU Construction Products framework.

Key topics and requirements

• Scope & product types: Defines types of metal lath (expanded flat, corrugated, ribbed, paperbacked wire lath, claylath, stainless options) and metal beads (angle, stop, featured, movement and corner movement beads).
• Materials & coatings: Requirements for corrosion‑resistant materials (steel, aluminium, stainless steel, zinc alloys) and coating thickness measurements.
• Dimensions & profiles: Specified dimensional checks including thickness/diameter, length, width, straightness and profile dimensions for beads and lath.
• Fire behaviour: Classification and requirements for reaction to fire and for use in fire‑protecting plastering systems (references to relevant fire test standards).
• Testing & sampling: Test methods for dimensional verification, coating thickness, straightness and other product characteristics.
• Conformity & factory controls: Procedures for type testing, Factory Production Control (FPC), traceability, marking and handling of non‑conforming products.
• Marking & CE: Requirements for marking, labelling and packaging; informative Annex ZA links the standard to EU Construction Products Directive procedures and CE marking.

Applications

• Provide a mechanical key and structural support for internal plaster layers on walls, partitions, ceilings, beams and columns.
• Protect and reinforce internal corners, edges and finishes with metal beads.
• Create depth gauges and controlled movement/expansion joints (movement beads allow ±1.5 mm movement at the plaster surface).
• Enable reliable specification and verification where fire‑protecting plastering systems are required.

Who uses this standard

• Manufacturers of metal lath and plaster beads (product design, FPC, labelling and CE compliance)
• Architects & specifiers (product selection for internal plastering, fire protection and finish requirements)
• Contractors & plastering installers (installation guidance, compatibility with plaster systems)
• Test laboratories & certification bodies (type testing, conformity assessment)
• Regulators & building control authorities (verification of CE marking and performance claims)

Related standards

• EN 13658-2 (External rendering)
• EN 13501-1 / EN 13501-2 (Fire classification)
• EN 1364 / EN 1365 series (Fire resistance test methods)
• EN 13914-2 (Design and application for internal plastering)
• Material standards referenced for steels, aluminium and coatings (e.g., EN 10088, EN 10169)
