Durability of wood and wood-based products - Quantitative determination of quaternary ammonium compounds in wood
This part of EN 351 establishes classification for preservative-treated wood in terms of preservative penetration and gives guidance on a classification of retention. These should be used as a basis for specifying preservative treatments for particular products.This part of EN 351 provides terminology to be used by the specifier when preparing a preservative treatment specification or product standard. It is not a treatment specification in itself.This part of EN 351 is applicable to the production of preservative-treated solid wood, including glued laminated timber, suitable for use in those service conditions defined by the use classes in EN 335-1. It doe
Durability of wood and wood-based products - Preservative-treated solid wood - Part 1: Classification of preservative penetration and retention
This part of EN 351 provides guidance on the general procedures used in obtaining samples of preservative-treated wood to determine the penetration and retention of wood preservative.This part of EN 351 is applicable for the production of preservative-treated solid wood, including glued laminated timber, suitable for use in those service conditions defined by the use classes in EN 335-1. However, the sampling guidance provided within this part of EN 351 may be applied for the subsequent examination of treated wood in service.

Forestry support - Part 6: Prevention of blue strain attack on sawn timber and logs
1.1 These methods cover the determination of various strength and related properties of wood by testing small clear specimens. 1.2 These methods represent procedures for evaluating the different mechanical and physical properties, controlling factors such as specimen size, moisture content, temperature, and rate of loading. 1.3 These methods do not cover the evaluation of lumber in structural size. 1.4 Guidance on the effect of specimen size on a property being evaluated is beyond the scope of these methods and should be sought elsewhere. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.6 The procedures for the various tests appear in the following: 1.6.1 Photographs of specimens. 1.6.2 Control of moisture content and temperature. 1.6.3 Record of heartwood and sapwood. 1.6.4 Static bending. 1.6.5 Compression parallel to grain. 1.6.6 Impact bending. 1.6.7 Toughness. 1.6.8 Compression perpendicular to grain. 1.6.9 Hardness. 1.6.10 Shear parallel to grain. 1.6.11 Cleavage. 1.6.12 Tension parallel to grain. 1.6.13 Tension perpendicular to grain. 1.6.14 Nail withdrawal. 1.6.15 Specific gravity and shrinkage in volume. 1.6.16 Radial and tangential shrinkage. 1.6.17 Moisture determination. 1.6.18 Permissible variations. 1.6.19 Calibration.
