This document specifies the minimum performance requirements in
biological tests for products for curative uses against specific
wood destroying organisms. It specifies the biological tests
required together with the efficacy criteria to be achieved in each
Chemicals against insects can act according to their specific
properties within a short time (fast acting) or only after a long
period (slow acting or with a deferred effect). Different tests and
efficacy requirements are needed for these various types of
curative wood preservatives.
This document is applicable to all wood preservative products
supplied for application in liquid form for curative uses against
attack by wood boring beetles. This document is also applicable for
products applied to prevent the growth of the dry rot fungus
This document is also applicable to products for curative uses
supplied for application as pastes, solids or in capsule form but
only where appropriate biological methods of test exist as
published European Standards.
This standard is used as a reference document for the
evaluation of efficacy of biocidal products PT8 (wood
preservatives) in the framework of the European Regulation on
Biocidal Products (EU) No 528/2012 (BPR).
This document is not applicable to products used as
This document is also not applicable for determining whether
specific curative products, used alone or in combination, are
effective in conferring long-term protection against attack by wood
destroying organisms. Preventive effectiveness can be determined
using EN 599?1 but only for products
that can be tested using the methods and interpretative procedures
defined in EN 599?1.
Annex A (informative) contains a guidance
on re-testing after making variations in product formulation.
Annex B (informative) contains some test
recommendations for specific curative products against other insect
species than Hylotrupes bajulus and Anobium punctatum.
