79.060.10 - Plywood

This document specifies the nature and limits of characteristics inherent in wood and manufacturing defects enabling the visual assessment of the plywood for allocation to an appearance class. This document applies to plywood, the surface veneers of which are made from hardwood species[1] including tropical and temperate hardwood. It does not apply to overlaid panels. [1] Conventionally, broadleaved species.

This document establishes general rules for the classification of plywood by its surface appearance. It concerns plywood made of hardwood including tropical and temperate hardwood, softwood and plywood derived from other lignocellulosic materials. It does not apply to overlaid plywood.

This document specifies the nature and limits of characteristics inherent in palm-plywood and manufacturing defects enabling the visual assessment of the plywood for allocation to an appearance class. This document applies to palm-plywood, the surface veneers of which are made from oil palm trunk.

This document specifies the requirements for cross laminated timber with rectangular cross-sections shaped by sawing, planning or other methods.
This document covers cross laminated timber, untreated or treated against biological attack.
This document does not cover timber treated by fire retardant products.

This European Standard sets out provisions regarding the performance characteristics for straight and curved structural cross laminated timber (X-Lam) both without and with large finger joints as a material for the manufacture of structural elements to be used in buildings and bridges.
This European Standard applies to cross laminated timber:
-   to be used in service class 1 or 2 according to EN 1995 1 1;
-   made of coniferous species and poplar listed in 5.1.5 of this standard;
-   built up of ...view more

This European Standard specifies the requirements for plywood, as defined in EN 313 2, for both general purpose use (non-structural application) and structural application in dry, humid or exterior conditions. It also gives a classification system based on the bending properties.
NOTE 1   This European Standard is referenced in EN 13986 for construction applications.
This standard can be appropriately applied for all plywood, including overlaid and coated plywood, but it does not cover materials...view more

ISO 13608:2014 specifies the terms, classifications, requirements, test methods, marking, for decorative veneered plywood with natural wood veneer, coloured veneer, laminated veneer, multilaminar veneer, and other types of veneer as decorative surface and plywood as a core panel, where the surface veneer thickness is less than 0,55 mm.

ISO 1096:2013 provides systems of classification of plywood panels based on general appearance and principal characteristics.

ISO 1954:2013 specifies dimensional tolerances of plywood panels (length, width, thickness) and tolerances for edge straightness and squareness.

This European Standard specifies a calculation method for the estimation of some mechanical properties of plywood (strength and stiffness) with a symmetrical composition. The resulting values are intended as predictive only.

This European Standard specifies, for plywood panels of any composition, symmetrical or not, a calculation method to derive some mechanical properties (strength and stiffness in bending, tension, compression, panel and planar shear) as well as density from the wood compounding the layers.
NOTE   Usually, the lay-up of the panels is symmetrical but, very often, the surface appearance of the face and the surface appearance of the back face differ, hence a difference between the mechanical propertie...view more

This European Standard provides information on the characteristic values for use in designing structures incorporating wood-based panels. The characteristic values given in this standard are to be used in accordance with EN 1995-1-1. When utilizing the classification system for derivation of plywood characteristic values, this European Standard can only be applied with reference to EN 636. This European Standard includes the characteristic values of the mechanical properties for plywood complyin...view more

This document gives guidance for the end user on the selection of plywood for application of various finishes for use in dry, humid, or exterior end-use conditions.

This document gives guidance on the selection of plywood for use in the different use classes as defined in EN 335 1.
The guidance given takes into account the natural durability classification for solid timber (see EN 350 2) together with other factors specific for plywood.
It does not consider durability against chemico-physical factors, such as weathering, nor does it consider the biological durability of the adhesive.
Guidance on precautionary measures for use is also given.

ISO 12466-2:2007 specifies requirements for determination of bonding quality class of plywood, blockboard, battenboard, and laminboard, bonded with thermosetting resins, according to their intended end uses.

ISO 12466-1:2007 specifies methods for determining the bonding quality of plywood, blockboard, battenboard, and laminboard, bonded with thermosetting resin, by shear testing.
