Fasteners for wood

FastenersSP tests most types of fasteners and performs production control of the area.

SP is the only laboratory in Sweden that is a Notified Body to carry out type testing of fasteners in load-bearing wood constructions according to EN 14592.

SP has long experience of fastener testing and perform regular testing according to standards EN 14592, EN 1382, EN 1383 and EN 409. EN 14592 is a harmonised standard for fasteners in load-bearing wooden constructions, which makes it necessary to CE mark these fasteners. The other standards are for withdrawal, pulling through the head and yield moment. SP is also a Notified Body for testing according to EN 14545, which includes nail plates and helps with testing according to EN 14566 Fasteners for mounting plasterboard. We can also customise testing to get values in the exact property that is desirable to test.
