CEN/TC 38/WG 27 - Exposure Aspects
To investigate the standardization of methods for measuring environmental emissions from wood preservatives during application, wood in service which has been treated with wood preservatives, and from treated wood after its service live. The first priority is to draft methods to measure environmental emissions from wood in service which has been treated with wood preservatives.

General Information
This document specifies a method for determining the leaching of active ingredients or other compounds from preservative treated wood by a semi-field method for Use Class 3 (outdoor above ground). The preservative treated wood can be tested with or without subsequently surface coating or other water-repellent treatment. The method is applicable to the testing of commercial or experimental preservatives or paint systems applied to timber by methods appropriate to commercial practice.

This European Standard specifies a method for determining the leaching of active ingredients or other compounds from preservative treated wood by a semi field method for Use Class 3 (outdoor above ground). The preservative treated wood can be tested with or without subsequently surface coating or other water-repellent treatment. The method is applicable to the testing of commercial or experimental preservatives or paint systems applied to non-durable timber by methods appropriate to commercial practice.

This CEN Report is intended to stimulate discussion of the test parameters and the test methodologies to achieve a consensus of opinion. This should allow test methods for emissions from preservative treated wood to be prepared and tested before they become standards. The standards will allow competent authorities and manufacturers of wood preservatives to comply with the requirements of the Biocide Products Directive(BPD.)

Frequently Asked Questions
CEN/TC 38/WG 27 is a Working Group within the European Committee for Standardization (CEN). It is named "Exposure Aspects" and is responsible for: To investigate the standardization of methods for measuring environmental emissions from wood preservatives during application, wood in service which has been treated with wood preservatives, and from treated wood after its service live. The first priority is to draft methods to measure environmental emissions from wood in service which has been treated with wood preservatives. This committee has published 11 standards.
CEN/TC 38/WG 27 develops CEN standards. The scope of work includes: To investigate the standardization of methods for measuring environmental emissions from wood preservatives during application, wood in service which has been treated with wood preservatives, and from treated wood after its service live. The first priority is to draft methods to measure environmental emissions from wood in service which has been treated with wood preservatives. Currently, there are 11 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
