This WPA Code of Practice provides detailed guidance on industrial wood preservation for specifiers, wood treaters and those involved with using treated wood.

Specifiers can gain an understanding of the correct way to specify wood preservative treatment in the UK to ensure that treated wood is fit for purpose in the service conditions in which each commodity has to perform.

This document provides guidance on the allocation of wood components to use classes and service factors applying to end-use situations which also help to make the decision on whether treatment is required or not.

Information is provided on quality assurance procedures that underpin confidence in the performance of treated material. The advantages of using wood treated under the WPA Benchmark Quality Assurance Scheme are explained.

Treatment plant managers can find detailed information on preparing wood for treatment and how to achieve the level of treatment to conform to
specifications received.

Plant operators can use the tables and techniques described here to assess the conformity of their procedures with the requirements of preservative treatment specifications. Included are sections on Factory Production Control, quality assurance and handling and storing treated wood.

Users of treated wood can learn about the characteristics of treated wood and its safety and disposal at the end of service life. The relevant sections should be consulted by users to ensure that the full benefits of additional durability conferred by treatment can be obtained while conforming to safety, health and environmental protection rules.
