This document applies to test methods designed to be used at the place of installation of the AEA, usually a laboratory and for various laboratory applications that require local extraction. They are used for commissioning after installation, for maintenance and for qualification purposes. For certain customer requirements additional or modified test methods can be necessary. This document includes product functional performance referring to product standard detailed in EN 16589-1. Occupational health and safety assessments methods are not included in this document. This document does not consider performance requirements for the extract air system associated with the AEA installation and therefore extract system performance is not part of the scope. This document does not confirm or establish a capture zone of an AEA capture device only the functional extract capacity and mechanical functions of the AEA.

This document gives guidance on the general procedures to be followed in the sampling and preparation for analysis of wood preservatives and preservative-treated timber. This document is applicable to the provision of appropriate samples for analysis which can be used to check the content of active and other ingredients in preservative formulations, and the content of active and other ingredients of wood preservatives in treated timber, either before, during or after the service life of the timber. NOTE 1 Methods of sampling creosote and creosote-treated timber are described in EN 1014-1, EN 1014-2 and EN 12490. These are used in preference to the recommendations in this document. NOTE 2 No attempt has been made in this document to lay down detailed procedures to be adopted for control purposes at manufacturing plants where large volumes of preservatives are sampled. Nor does it attempt to establish procedures for checking the compliance of batches of treated timber with specifications demanding a defined level of treatment (see 6.2).
