Methods for sampling and analysing timber preservatives and preservative-treated timber
Sets out a series of methods for sampling and analysing timber preservatives and preservative-treated timber. Methods are grouped into five sections, i.e. sampling preservative liquids and preservative-treated timber, determination of preservative penetration, analysis of preservative retention, analysis of preservative solution concentration, and determination of presence of sapwood. Appendices give examples of a test certificate and means for demonstrating compliance with this Standard.
