BS 1088:2018 pdf download – Marine plywood – Requirements BS 1088 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. NOTE 1 where marine plywood is to be used in building construction, attention is drawn to the ConstructionProducts Regulations 2013 [1].Conformity with these can be verified through demonstrating conformity withBS EN 13986. NOTE 2 When used in building construction, good site practice with particular reference to protection of thebuilding elements against wetting is of the highest importance for ensuring the intended results for the building. 2Normative references The following documents are referred to in the text in such a way that some or all of theircontent constitutes provisions of this document.
