This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential
22、 requirements of EU Directive(s). For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document. No existing European Standard is superseded.

28、rs 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 o
