BS EN 14566:2008 PDF FREE.MECHANICAL FASTENERS FOR GYPSUM PLASTERBOARD SYSTEMS – DEFINITIONS, REQUIREMENTS AND TEST METHODS.
BS EN 14566 specifies the characteristics and performance of mechanical fasteners, including nails, screws and staples, intended to be used for the fixing of gypsum plasterboard, gypsum boards with fibrous reinforcement, products from secondary processing and suitable ancillary products as shown in Figure 2, to timber and metal, as appropriate, in building construction works. The fasteners secure the board to the framing enabling its surface to be finished by jointing or plastering to receive decoration. They can also be used for the constwction of the framing and for the connection between substructure and load bearing components and for fixing boards together. Mechanical fasteners contribute to the stability of the assembly.
This European Standard covers the following product performance characteristics: reaction to fire and flexural strength to be measured according to the corresponding European test methods.
It provides for the evaluation of conformity of the product to this European Standard.
This European Standard also covers the additional technical characteristics that are of importance for the use and acceptance of the products by the construction industry and the reference tests for these characteristics.
This European Standard does not cover nails, screws and staples intended for use with materials other than plasterboard and the plasterboard based products referred to above and their associated system components.

4 Requirements
4.1 Reaction to fire
Plasterboard nails, screws and staples made from steel are classified Al (EN 13501-1) (no contribution to fire) without testing when they are not coated.
When they have an organic coating, their contribution to reaction to fire in end use condition is so small in the total assembly that they have no influence on the classification of the system tested.
4.2 Flexural strength (bending behaviour)
When tested in accordance with 5.5 no fastener shall show signs of breakage or cracking.
