BS 1088:2018 specifies requirements for two classes of marine plywood:

standard; and
lightweight,

intended for use primarily in the manufacture of marine craft and in other marine and waterwayapplications.The requirements also take into consideration the use of marine plywood in building construction.BS 1088 addresses in particular the resistance of plywood to bio-deterioration and loss of bondstrength with time. It does not make provision for other properties which might additionally berelevant in a particular end use.Plywood made in accordance with this standard might also need to meet additional requirements inlegislation and/or standards specific to its end use that are not covered by this standard.With particular reference to building construction, experience has shown that rapid ingress of waterat the panel edge during the build process can cause differential swelling in the core, resulting inlocalized catastrophic rupture of the wood fibres, thus giving the appearance of delamination. Ifsubsequent integrity of the waterproof envelope of the building is not maintained, similar problemscan arise. BS 1088 cannot make provision for such events since the choice of veneer species is basedonly on density and resistance to bio-deterioration.Cross References:BS EN 324-1BS 1203BS EN 324-2BS EN 314-1BS EN 326-1BS EN 322BS EN 636BS EN ISO 3166-1BS EN 335:2013 BS EN 350:2016BS EN 314-2:1993DD CEN/TS 1099BS EN ISO 9000 BS EN 1995-1-1Construction Products Regulations 2013BS EN ISO 9000-1BS EN 313-2BS EN 326-3BS EN 13986BS EN 923BS 6100-4.3:1984BS EN ISO 9001:2015BS ISO 9000-2:1997
