It is intended to complement BS EN 12365 by giving material requirements to enable agreement between the supplier and user (see BS EN 12365-1 clauses 5.3, 5.4 and 5.5) and to give guidance on the grades contained within that standard.It applies to gaskets, co-extruded glazing beads, weatherstrips, cellular adhesive glazing tapes, sheathed cellular products, pile products and those incorporating fusion welded or moulded corner joints or any other appropriate method of jointing used in windows, doors, conservatories and curtain walling. The performance of a gasket or weatherstrip is dependent on its design and the design of the system into which it is fitted. This is assessed by testing the performance of the complete assembly, for instance by testing to BS7412 for PVC-U windows. Similar tests may be necessary for windows of other materials. This specification is intended to give the system designer and window fabricator information necessary to ensure the effective performance of the finished product.
