This draft European Standard specifies the requirements for the following types of dowel-type fasteners: nails, staples, screws, dowels, and bolts with nuts. Only dowel-type fasteners for structural use in load bearing timber structures, and manufactured from steel, are covered by this European Standard. In addition, this draft European Standard covers also the use of screws: to fix roof or cladding elements to the timber structure, with or without insulation layers; and as reinforcement inserted in timber or in a glue laminated timber element to improve its resistance to compression perpendicular to the grain. This draft European Standard specifies also the assessment and verification of constancy of performance (AVCP) procedures and includes requirements for marking of these products. This draft European Standard covers dowel-type fasteners that may be coated for the following purposes: corrosion protection; lubrication (to facilitate insertion); withdrawal enhancement and/or collation for staples (adhesive and/or resin coatings). This draft European Standard does not cover fasteners treated with fire retardants to improve their fire performance, nor does it cover glued-in rods.
