Quality Standards

(BS) EN 300 : 2019 Oriented Strand Boards (OSB) – Definitions, classification and specifications This defines the terms, establishes a classification and specifies requirements for OSB.  The values appearing in this standard relate to the products properties but they are not characteristic values to be used in design calculations. See OSB Use Classes and durability issues   – this was …

(BS) EN 314-2: 1993 (confirmed in 2013) Plywood – Bond quality – Requirements This part of the standard specifies the requirements for bonding classes of veneer plywood according to their end uses.  It lists three classes of bond quality. Bond Class 1: Dry conditions ‒ interior applications with no risk of wetting. This is equivalent to a moisture content in the plywood corresponding …

Plywood – Bond quality – Test methods This standard specifies methods for determining the bonding quality of veneer plywood, by shear testing. Before carrying out the shear tests the plywood samples are required to undergo a sequence of pre-treatments e.g. section 5.14 calls for immersion for 72 hours (±1) in boiling water followed by cooling in water at 20°C (±3°) …

(BS) EN 636:2012+A1:2015 Plywood – Specification This gives the requirements for plywood for general purpose use and for structural (load bearing) applications in dry, humid and exterior conditions. It also gives a classification based on bending properties. Amendment 1 : 2015 makes the following modifications to EN 636 : 2012 a) The scope now clarifies that the standard includes overlaid …

List of Individual Standards for Wood-based Panels The UK and EU follow the same principles for the standards listed below. For ease of use we have combined the titles. For the UK, the titles simply have ‘BS’ for (British Standard) added. When a standard has been reviewed and updated, that date is integrated into the standard title. When a standard …

(BS) EN 314-1: 2004 (confirmed 2014) Plywood – Bond quality – Test methods This standard specifies methods for determining the bonding quality of veneer plywood, by shear testing. Before carrying out the shear tests the plywood samples are required to undergo a sequence of pre-treatments e.g. section 5.14 calls for immersion for 72 hours (±1) in boiling water followed by …

Plywood production problems? The countermeasures you want to know are here! Guide: China’s plywood production is in full swing, but the quality of plywood on the market is mixed. Many small and medium-sized enterprises are lack of production experience and can not effectively control the problems in plywood production. To improve the quality of plywood, we should know the possible …

Strength & Stiffness Plywood and OSB structural panels possess inherent strength and stiffness. They resist bending or deflection, racking or shape distortion and impact damage. Because of their split resistance, wood structural panels possess excellent fastener-holding properties and can be nailed very near panel edges. For most applications, stiffness is one of the biggest benefits of wood structural panels. Excellent …
