A quick overview
2272:2006 (usually called AS2272) The Australian marine
plywood standard. Plywood made to this standard is amongst the very
best in the world. Has legal effect in Australia and New Zealand.
BS1088-1:2004 (Usually called BS1088). The British maine plywood
standard. Probably the most widely known standard for marine ply
in the world. Extensively used by the asian plywood mills as
well as the European. Has no legal effect outside the UK.
Some European manufacturers can provide a legal certificate of
AS/NZS 2271:2004 The Australian exterior
grade of plywood standard. Specifies lower quality veneers than
AS 2272, but does require waterproof glue. (Although some is only semi
waterproof, B Bond, it is important to check the stamp on the sheet).
Exterior plywood with an A Bond is useful in many parts of marine
AS/NZS 2269:2008 The Australian structural
plywood standard. This defines the F strength standards which
can be relied upon when using F rated plywoods, such the plywood which
complies with AS 2272. Structural plywood is made pretty much
without reference to its appearance, so it can look pretty ugly.
Marine Plywood to AS 2272 has either AA faces or OO faces. (OO is
defined in the AS 2272 standard, they are similar to a B grade face).
Australian exterior plywood is typically AC and structural is CD or even
DD. Other combinations are possible.
Imported marine ply is
usually described by the importer as AA or BB and we would generally agree
with those descriptions.
AS 2271 and AS 2269 go into considerable detail
about these veneer grades. this is a quick summary.
- Quality A —a high quality appearance grade, suitable for clear
- Quality S —an appearance grade that permits natural
characteristics as a decorative feature.
- Quality B —an appearance grade suitable for high quality paint
(B) Back veneer qualities:
- Quality C —a non-appearance grade with a solid surface.
- Quality D —a non-appearance grade with permitted open
imperfections. (Often large open knot holes.)
- Type A bond is produced from phenol formaldehyde
(PF) resin that sets permanently under controlled heat and pressure
and will not deteriorate under wet conditions, heat or cold. It is
readily recognised by its black colour. The Type A bond is specified
in AS2272 for marine plywood, AS2269 for structural plywood and AS2271
for exterior plywood used under conditions of long term full exposure
or under wet or damp conditions.
- Type B bond is produced from melamine fortified
urea formaldehyde resin (MUF) which again sets under controlled heat
and pressure. Type B bond is included in the AS2271 exterior plywood
standard for applications involving up to two years maximum exposure
such as formwork plywood or plywood used in semi exposed applications
such as exterior door skins.
- Type C and Type D bonds are both interior bonds
and are not recommended for any purpose where exterior use or wet or
damp conditions are involved, or where long term load bearing
requirements exist. The glue line is light coloured.
