Foreword
This document (EN 599-1:2009) 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text or by endorsement, at the latest by January 2010, and conflicting national standards shall be withdrawn at
the latest by January 2010.
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 599-1:1996.
Significant technical differences between this edition and EN 599-1:1996 are as follows:
 The scope now emphasises that this standard is not a performance standard but a standard for
characterising the efficacy of wood preservatives, based on data derived from the biological tests that it
specifies, supplemented by, in certain cases, data from field tests. This European Standard provides a
basis for establishing preservative retentions for timber when specified in conjunction with EN 351-1
taking into account necessary local considerations. It points out that at present not all natural ageing
factors which may affect the stability of active ingredients for wood preservatives can be assessed by
standardized methods but have nevertheless to be taken into account in the development of preservative
products capable of being effective in service. It also allows for preservatives that have been used
successfully and legally before the standard was to have their efficacy confirmed in accordance with the
general principles of the standard (so called “grandfather-clause”).
 This document now provides for the use of data from CEN/TS 839, in specific cases, as a method for the
assessment of preservatives designed for superficial applications.
 In Annex A “Guidance on re-testing after making variations in product formulation”, requirements have
been clarified by the provision of diagrams.
 Production control has been withdrawn from Clause 9 and transferred to a new informative annex (now
Annex B).
 A new normative annex on the validity of test results from former standards after their revision has been
added (now Annex H).
EN 599 consists of two parts. Part 2 (EN 599-2, Durability of wood and wood-based products —
Performance of preventive wood preservatives as determined by biological tests — Part 2: Classification
and labelling) will be revised later once the exact requirements of the Biocidal Products Directive have been
finalised.
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, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
This part of EN 599 is one of a series and should be used in conjunction with EN 599-2, EN 335-1 and
EN 335-2, which describe the service conditions for treated wood in terms of use classes, and EN 351-1,
which describes a classification system for preservative treated wood in terms of preservative penetration and
gives guidance on classes for retentions. The need for wood preservatives depends in part on the natural
durability of the wood and therefore this part of EN 599 should also be used in conjunction with EN 350-1,
EN 350-2 and EN 460.
1 Scope
This part of EN 599 specifies for each of the five use classes defined in EN 335-1, the biological tests required
for evaluating the efficacy of wood preservatives for the preventive treatment of solid timber, together with the
minimum ageing tests required for the respective use class. It provides the method for calculating the critical
value of a preservative. The critical value is the value that shall be used to calculate the recommended
retention of the preservative appropriate for specific service conditions. The critical value is not necessarily the
recommended retention or the minimum retention level for the preservative. The wide range of hazards,
exposure conditions and service life requirements across Europe make it necessary to allow for local
considerations in the calculation of the required preservative retention; EN 351-1 provides for the critical value
to be adjusted to take account of these factors.
This part of EN 599 is applicable to all wood preservative products supplied for application in liquid form for
the preventive treatment of timbers (structural and non-structural) against wood-attacking fungi, wood-
attacking insects and marine borers as described in EN 335-1. However, it is applicable to products for
preventive treatments against fungi causing disfigurement (blue stain) of wood in service if this forms part of
the overall preventive efficacy of the product.
This part of EN 599 does not necessarily take into account all the factors which may affect the stability of
active ingredients in preservative treated wood. These factors include ultra-violet light and microbiological
agencies capable of degrading components of the preservative. Such factors are an integral part of exposure
in field trials but are subject to natural variation and their impact is not directly assessed in the field trial
methods included in this standard. Methods are in development to assess the impact of these factors but are
not finalised and cannot be included in this revision of this part of EN 599. Because such factors could, in
service, significantly affect the active ingredient’s suitability for its intended purpose, the manufacturer/
producer is expected to ensure and be able to provide evidence that its stability, at the recommended
retention of the preservative product, has been adequately assessed.
This part of EN 599 is not applicable to wood preservative products supplied for application as pastes, solids
or in capsule or gaseous form because these cannot be tested without modification of the biological tests cited
in this standard. It does not apply either to wood preservative products for remedial (curative) treatments, to
those applied to prevent fungi causing sap stain on green (unseasoned) timber or to those applied solely to
prevent fungi causing disfigurement (blue stain) of wood in service.
NOTE 1 The nature of the laboratory and field tests required in this part of EN 599 to demonstrate efficacy of a wood
preservative are such that the time required generating the data is many months or years, depending upon the properties
of the wood preservative and the use class in which the treated wood is to be exposed.
For preservative products which have already been placed on the market without significant formulation variation (see
Annex A) before the end of 1990 and which can demonstrate a record of having been used lawfully and successfully in
accordance with local technical traditions during this period, national standards bodies or independent authorities
nominated by them, may declare critical values for use within their territories.
NOTE 2 For re-testing after making variations in product formulation, guidance is given in Annex A.

4 Assignment to use class(es)
Each product shall be assigned to one or more use class as described in EN 335-1.
5 Efficacy
5.1 Principal requirements
5.1.1 Each product shall be tested in accordance with the tests specified in Table 1 to Table 5, taking into
consideration the following:
a) relevant use class (see Clause 6);
b) method of application (see Annex C);
c) type of wood to which it is intended to be applied (see Annex D);
d) which insect species (if any) it is to protect against;
e) whether it is only be used under a coating.
Where Table 1 to Table 5 require the wood preservative product to be resistant to evaporative ageing and/or
leaching, tests in accordance with EN 73 and/or EN 84 shall be carried out separately (see Annex E).
5.1.2 Using the relevant criteria given in Table 1 to Table 5, the b.r.v. shall be established for each test at
an application rate at or below the given maximum application limit (see Annex G).
5.1.3 In those European standard biological tests which provide for the derivation of toxic values, the b.r.v.
shall be the mid toxic value (m.t.v.) except in the following cases:
a) in tests with insects using EN 47, if the mortality at the lower toxic value is less than 80 %, then the upper
toxic value shall be used as the b.r.v;
b) in tests with insects using EN 20-2 or EN 49-2, if the number of live larvae/emerged beetles at the lower
toxic value exceeds 20 % of the number from the solvent controls, then the upper toxic value shall be
used as the b.r.v;
c) in EN 113 tests, if the mean mass loss at the lower toxic value is greater than 10% (m/m), then the upper
toxic value shall be used as the b.r.v.
5.2 Additional requirements in Table 1 to Table 5
5.2.1 Where local conditions require the wood preservative product to have additional biological efficacy, or
to support the claims of manufacturers or the demands of specifiers, the product shall also be tested in
accordance with the relevant additional/local tests given in Table 1 to Table 5.
NOTE 1 Field tests which vary in form or geographical location from the procedures prescribed in EN 252, EN 275 and
EN 330 may provide relevant supplementary data for confirming retention requirements in EN 351 which are derived from
critical values according to EN 599.
NOTE 2 See Annex F.
5.2.2 The most relevant application process specified in the respective EN methods of biological test shall
be used even though this may not correspond precisely with the process intended for the test product in
practice.
5.2.3 Wood preservative products in use class 1 shall be effective against specific or all wood boring
beetles specified in this part of EN 599. There is no risk of fungal attack in this use class.
Tests of the product shall be carried out against one of the following:
a) unless b) or c) is applicable and is selected, all or each relevant individual beetle(s) "Hylotrupes bajulus
(H) "; "Anobium punctatum (A)"; and "Lyctus brunneus (L)"; or;
b) the most tolerant beetle species, if the product is based on insecticide(s) for which data already exist
(aged or unaged) which show different activities against the different beetle species, that is the mid toxic
value of the least tolerant beetle species is less than 80 % of the mid toxic value of the most tolerant
beetle species; or;
c) as defined in the column "for all beetle spp (I)", if the product is based on insecticide(s) for which data
already exist (aged or unaged) which show more or less equal activity against all beetle species, that is
the mid toxic value of the least tolerant beetle species is equal to or greater than 80 % of the mid toxic
value of the most tolerant beetle species.
5.2.4 Additional tests need only be conducted when necessary to meet or confirm local or regional
requirements, the stated requirements of specifiers or the specific claims of manufacturers (see 5.2.1).
5.2.5 The product shall be tested according to EN 46-2 if a repellent or ovicidal activity is claimed.
5.2.6 Leaching in accordance with EN 84 is not required for products intended for use classes 1
and 2 which shall be protected from prolonged exposure to rain or other accidental and temporary forms of
wetting during transport and installation. If such protection cannot be ensured, products intended for use in
use classes 1 and 2 to be applied by methods which will not achieve lateral penetrations greater than 3 mm,
shall be tested after leaching to EN 84.
Leaching according to EN 84 cannot be used in conjunction with EN 20-1 and EN 20-2; therefore the b.r.v.
against Lyctus brunneus (L) where there is a leaching hazard shall be deemed to be equal to that for:
Hylotrupes bajulus (H) or
Anobium punctatum (A) after leaching; whichever is the greater.
5.2.7 For the anti-termite qualification "T", a superficial application product shall have been tested in ready
for use form:
a) according to EN 46 or the relevant beetle test and have achieved the criteria to provide the biological
reference value for this test and;
b) according to EN 118:2005 when applied at 200 g/m of treating product and have achieved the efficacy
criteria defined for termites in this part of EN 599.
NOTE European Standard EN 118:2005 does not provide an adequate test of all the modes of action of currently
available preservative products. By the time a new version of EN 118 or an alternative European test standard providing
more realistic test results for efficacy against termites is produced, other applicable evaluation methods may be used to
provide the b.r.v.
5.2.8 EN 20-2 shall not be used for water-dispersed or water-soluble types of wood preservative products
because the scope of the method does not permit its use with such products.
5.2.9 When deriving the mid toxic value, if the mortality at the lower toxic value in EN 47 is less than 80 %,
the upper toxic value shall be used as the b.r.v. In EN 20-2 and EN 49-2, if the number of live larvae/emerged
beetles at the lower toxic value exceeds 20 % of the number from the solvent controls, the upper toxic value
shall be used as the b.r.v.
5.2.10 The required retention in the respective laboratory tests shall not exceed the manufacturers
recommended loading and shall be achieved for the laboratory tests by full impregnation with a diluted
solution of the product.
NOTE In industrial practice, products intended for penetrating treatment processes are applied in ways which result
in a wide range of retentions of the product in treated sapwood. For example, in Scots pine (European redwood) (Pinus
sylvestris) sapwood, high pressure systems (for example vacuum-pressure) would normally be expected to achieve close
to mean retentions of 600 kg/m³ of treating product. Low and non-pressure systems (for example double-vacuum,
prolonged immersion) would not normally be expected to achieve mean retentions of more than 300 kg/m³ of treating
product.
5.2.11 EN 113 tests shall be used as the specified test against basidiomycetes for products intended for use
in use class 2 applied by superficial application.
5.2.12 CEN/TS 839 is not a required test for use class 2. However, where products have been tested in
accordance with CEN/TS 839 for use class 3 (uncoated), these products may also be used in use class 2
without further testing in accordance with EN 113. In this case, the b.r.v. for protection against basidiomycetes
in use class 2 may be determined from CEN/TS 839 plus ageing according to EN 73, using the criteria
described in 5.2.19, and where relevant EN 84 as described in 5.2.6.
5.2.13 EN 113 tests with Coriolus versicolor are not required for products intended only for use class 2.
5.2.14 Products for use in use class 2 intended to be effective against fungi causing blue stain in service
shall be tested in accordance with EN 152-1 or EN 152-2 but after ageing in accordance with EN 73 or after
natural weathering as given in EN 152.
5.2.15 In order to derive the critical value, the biological reference value in grams per square metre shall be
deemed to be equivalent to twice the biological reference value established in kilograms per cubic metre in the
EN 113 test.
5.2.16 When deriving the mid toxic value, the mean loss in mass of the samples at the lower toxic value in
the EN 113 test shall not exceed 10 % (m/m); if this value is exceeded then the upper toxic value shall be
taken as the biological reference value.
5.2.17 Products proposed for superficial treatments and intended for use class 3 without any paint or coating
shall be tested in accordance with CEN/TS 839 after EN 73 and EN 84 separately.
5.2.18 Products proposed for superficial treatment and intended for use class 3 under a paint or other
coating applied before exposure in use shall be tested either according to CEN/TS 839 after EN 73 and EN 84
separately or in accordance with EN 113 after EN 73 and EN 84 separately, or according to EN 330 as well as
with EN 113 after EN 73.
5.2.19 Products intended for use class 3 shall be tested according to the application options in accordance
with either EN 113 or CEN/TS 839 using Coriolus versicolor, only if this is required as an additional biological
test; if used, efficacy shall be demonstrated either in Scots pine (Pinus sylvestris) or in beech (Fagus
sylvatica), or in both, depending whether efficacy is claimed or specified for softwoods, for hardwoods, or for
both.
NOTE EN 113 or CEN/TS 839 tests with Coriolus versicolor need not be conducted in both types of wood providing
there is evidence that the active ingredient(s) in the product are equally effective in both timbers; in this case the b.r.v. for
the product in beech can be used for both timbers. If the evidence shows the active ingredient(s) to be more effective in
Scots pine, then the b.r.v. for the product for use on softwoods should be derived from tests in Scots pine to avoid over
specification of biocides.
5.2.20 For the purposes of deriving critical values from CEN/TS 839, the biological reference value shall be
the lowest application level (in grams per square metre) at which the mean mass loss is less than 3 %,
providing that:
a) no more than one of the test specimens at that level (exposed to any particular ageing procedure and any
particular test fungus), shows internal decay; or
b) of the specimens which show signs of decay exclusively at their surface, no more than one has a mass
loss greater than 3 % but less than 5 %, irrespective of the number of valid replicates.
5.2.21 The biological reference value shall be the amount of the product at which the values for the nominal
n e
mean rating for decay (V ) and the mean decay ratings for external surfaces and joint faces (V ) and the mean
i
decay ratings for internal conditions (V) are equal to or better than those for the reference preservative after
the untreated control specimens have reached a median rating of ≥ 3; in addition the number of replicates
TP
rated 2 or above for the product (R2 ) shall not exceed the number rated 2 or above for the reference
R
preservative (R2 ).
5.2.22 Products proposed for penetrating treatments and intended for use class 3 without any paint or
coating shall be tested in accordance with EN 113 after EN 73 and EN 84 separately.
5.2.23 Products proposed for penetrating treatments and intended for use class 3 under a paint or other
coating applied before exposure in use shall be tested either according to EN 113 after EN 73 and EN 84
separately or in accordance with EN 330 as well as with EN 113 after EN 73.
5.2.24 Products intended for use in use classes 4 and 5 shall be tested in accordance with EN 113 using
Coriolus versicolor and for this fungus, efficacy shall be demonstrated either in Scots pine or in beech, or in
both, depending whether efficacy is claimed or specified for softwoods, for hardwoods, or for both.
NOTE EN 113 tests with C. versicolor need not be conducted in both types of wood providing there is evidence that
the active ingredient(s) in the product are equally effective in both timbers; in this case the b.r.v. for the product in beech
can be used for both timbers. If the evidence shows the active ingredient(s) to be more effective in Scots pine, then the
b.r.v. for the product for use on softwoods should be derived from tests in Scots pine to avoid over specification of
pesticide.
5.2.25 Products intended for use in use class 4 shall be tested in accordance with EN 252 only if required as
an additional biological test. The relevant code for conformance with field test requirements (see EN 599-2)
shall be used only if the biological reference value for tests in accordance with EN 252 has been taken into
account before deriving the critical value.
5.2.26 Tests in accordance with ENV 807 shall be carried out and the nominal effective retention calculated
in accordance with Clause 10 and Annex E of ENV 807:2001. Data derived from the screening test method
described in Annex A of ENV 807:2001 are not admissible.
NOTE The b.r.v. can be derived also from exposure periods less than 32 weeks if for the exposure period of
24 weeks no mean mass loss value below 3,0 % is reported for the reference product, but, values suitable for deriving the
b.r.v. are available for lower exposure periods (e.g. for 16 and 24 weeks exposure). In this case the highest concentration
of the reference product should be used for the calculation which shows a mean mass loss < 3,0 % at the shorter
exposure time and a mass loss of > 3,0% at the longer exposure time.
5.2.27 The biological reference values for EN 252 and EN 275 shall be determined separately for each of
two or more different field test sites in each case. The test sites shall have different soil/marine characteristics
and be located in different geographical regions giving different climatic conditions; at least one site shall be
within geographic Europe.
In the case of EN 275, the reference specimens to be included in the test method shall be treated with either:
a) the reference preservative at concentrations of 2,6 % (m/m) and 0,6 % (m/m), to provide two sets of
specimens with retentions of approximately 18 kg/m³ and 4 kg/m³ respectively; or
b) the alternative reference preservative at 5 % (m/m) and 1,2 % (m/m) to provide two sets of specimens
with retentions of approximately 30 kg/m³ and 7 kg/m³ respectively.
The biological reference value for the product shall be derived by plotting the rating against the retention of
preservative for both the reference preservative and the product under test for each site. The upper nominal
retention of the product is calculated as that retention which has a rating equal to the rating of the higher
retention of the reference preservative. The lower nominal retention of the product is calculated as that
retention which has a rating equal to the rating of the lower retention of the reference preservative.
If variability in the test results yields more than a single upper or lower nominal retention value for the product,
in any given test site the mean of all the upper or lower values shall be used for deriving the biological
reference values.
If after five years there is no biological attack at the upper retention of the reference preservative, the test shall
be continued until attack occurs in these samples.
If after five years the mean rating for the biological attack in the upper retention of the reference preservative
is less than 0,5, then the biological reference value for the product shall be derived from both the upper and
lower nominal retentions of the product.
If after five years the mean rating for the upper retention of the reference preservative is equal to or greater
than 0,5, then the biological reference value for the product shall be derived from the upper nominal retention
of the product only.
The upper biological test value shall be equal to the upper nominal retention of product divided by 0,75 and
the lower biological test value shall be equal to the lower nominal retention of product divided by 0,17. The
biological reference value for deriving the critical value shall be the higher of the two nominal mean values
calculated from the upper and lower biological test values at each site.
If the product is claimed to be effective against termites (T) one of the test sites shall be recognised as having
active termites.
5.2.28 Northern waters (N) are those with temperatures normally ranging from below 0 °C to 20 °C (north of
latitude 50°N); southern waters (S) are those with temperatures normally ranging from 10 °C to 30 °C (south
of latitude 45°N).
If specific test data for a product exist only for either northern or southern waters of the geographic European
area respectively, the biological reference value from one can be derived from tests conducted in the other by
application of the following factors:
b.r.v. for southern waters = 1,5 b.r.v. derived in northern waters.
*
b.r.v. for northern waters = 0,67 b.r.v. derived in southern waters.
*
6 Tests for efficacy according to use class
