Wood preservatives - Determination of the protective effectiveness against Anobium punctatum (De Geer) by egg-laying and larval survival - Part 2: Application by impregnation (Laboratory method)
This European Standard specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against Anobium punctatum (De Geer) by egg-laying and larval survival in wood which has been treated previously by full impregnation. This method is applicable to:
- water-insoluble chemicals which are being studied as active insecticides;
- organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates;
- organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates, and
- water-soluble materials, for example salts.
NOTE This method can be used in conjunction with an ageing procedure, for example EN 73.

Das Verfahren gilt für:
- wasserunlösliche Chemikalien, die als wirksame Insektizide untersucht werden;
- organische Formulierungen in deren Anlieferungszustand oder in Form von im Laboratorium hergestellten Verdünnungen von Konzentraten;
- organische wasserdispergierbare Formulierungen in deren Anlieferungszustand oder in Form von im Laboratorium hergestellten Verdünnungen von Konzentraten; und
- wasserlösliche Stoffe, zum Beispiel Salze.
ANMERKUNG Das Verfahren kann in Verbindung mit einer geeigneten Alterungsbeanspruchung, zum Beispiel nach EN 73, angewendet werden.

European foreword
This document (EN 49-2:2015) has been prepared by Technical Committee CEN/TC 38 “Durability of wood
and wood-based products”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by February 2016 and conflicting national standards shall be withdrawn
at the latest by February 2016.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 49-2:2005.
Significant technical differences between this document and EN 49-2:2005 are as follows:
a) generalization of material for preparing the egg-laying zones;
b) introduction of new harmonized specifications for wood quality.
EN 49, Wood preservatives ― Determination of the protective effectiveness against Anobium punctatum (De
Geer) by egg-laying and larval survival, consists of two parts:
— Part 1: Application by surface treatment (Laboratory method);
— Part 2: Application by impregnation (Laboratory method).
EN 49-1 is required to enable effectiveness assessments of wood preservatives which are intended to be
applied by surface treatment and EN 49-2 those which are intended to be applied by impregnation.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
Introduction
This document describes a laboratory method of testing which gives a basis for assessment of the
effectiveness of a wood preservative, against Anobium punctatum. It allows the determination of the
concentration at which the product prevents the development of infestation from egg laying.
The method simulates conditions which can occur in practice on timber which has been treated some time
previously with a deeply penetrating wood preservative and on which eggs of Anobium punctatum are laid.
This laboratory method provides one criterion by which the value of a product can be assessed. In making this
assessment the methods by which the preservative may be applied should be taken into account. It is further
recommended that results from this test should be supplemented by those from other appropriate tests, and
above all by comparison with practical experience.
When products which are very active at low concentrations are used it is very important to take suitable
precautions to isolate and separate, as far as possible, operations involving chemical products, other
products, treated wood, laboratory apparatus and clothing. Suitable precautions should include the use of
separate rooms, areas within rooms, extraction facilities, conditioning chambers and special training for
personnel (see also Annex D for environmental, health and safety precautions).
1 Scope
This European Standard specifies a method for the determination of the protective effectiveness or the toxic
values of a wood preservative against Anobium punctatum (De Geer) by egg-laying and larval survival in
wood which has been treated previously by full impregnation. This method is applicable to:
— water-insoluble chemicals which are being studied as active insecticides;
— organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates;
— organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of
concentrates, and
— water-soluble materials, for example salts.
NOTE This method can be used in conjunction with an ageing procedure, for example EN 73.
2 Normative reference
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
EN ISO 3696, Water for analytical laboratory use - Specification and test methods (ISO 3696)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
representative sample
sample having its physical or chemical characteristics identical to the volumetric average characteristics of the
total volume being sampled
3.2
supplier
sponsor of the test (person or company providing the sample of wood preservative to be tested)
4 Principle
The treated test specimens are exposed to gravid females of Anobium punctatum. The numbers of eggs laid,
the numbers of eggs hatched, and the numbers of the surviving larvae are compared with those in untreated
control test specimens. If the preservative has been prepared in the laboratory by dilution of a concentrate or
by dissolution of a solid, the resulting attack is also compared to that in solvent or diluent treated control test
specimens.
Depending on the test being carried out either
— on a set of test specimens of a susceptible wood species that is impregnated with a solution of the
preservative, or
