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.
