2、S EN 14080:2013 BRITISH STANDARDNational forewordThis British Standard is the UK implementation of EN 14080:2013. It supersedes BS EN 385:2001, BS EN 386:2001, BS EN 387:2001, BS EN 390:1995, BS EN 391:2002, BS EN 392:1995, BS EN 1194:1999 and BS EN 14080:2005 which are withdrawn.BSI, as a member of

3、 CEN, is obliged to publish EN 14080 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard. The committee expressed the following concerns: General UK practice up until

4、now has been to include a wider list of species, including hardwoods, from which glulam is to made, (as stated in the previously published standard BS EN 336), than is presented in EN 14080; The upper limits of thickness permitted for laminations that are used in the manufacture of softwood glued so

5、lid timber (GST) could lead to service issues arising from excessive distortion or splitting in certain environments, especially those in which there are fluctuations in moisture content.An informative National Annex entitled Guidance on the implementation of BS EN 14080:2013 in the UK has been incl
