DIN EN 330:2015-01 EN 330:2014 (E) 5 Introduction This European Standard describes a method of test for wood preservatives that are intended for use under a surface coating in ti

29、mber to be exposed to the weather and out of contact with the ground (Use Class 3, EN 335). The main objective of the test is to evaluate the relative effectiveness of the preservative applied to jointed samples of Pinus sylvestris L sapwood by a treatment technique relevant to its intended practica

30、l use. Effectiveness is evaluated relative to a reference material. The method is concerned with protection against attack by the complete sequence of microorganisms occurring under natural conditions, including those basidiomycete fungi that eventually cause decay. It takes into account the effects

31、 of weathering (light, rain and heat) on the effectiveness of a wood preservative under a coating. The method does not accelerate the rate of decay (see Note), however the coating failure occurs immediately at the test start, that is even sooner than in badly designed and poorly maintained joinery e

32、xposed under the same conditions. The method may be used, after modification, for other purposes including evaluating the effectiveness of a test preservative as follows: in protecting timbers of a different wood species; under different types of coating. Since the L-joints are exposed to natural ou

33、tdoor conditions during the test period, variations in test conditions from one location to another have to be expected. Differences in climate, especially rainfall, will influence the general rate of development of decay fungi. However, by comparing the results obtained for the test preservative wi

34、th those obtained with the reference material and with those for untreated, control L-joints, the relative protective effectiveness of the preservative under test can be evaluated. NOTE The coating is intended to make the technique relevant to the end use albeit the test pieces are badly maintained

35、and designed in order to accelerate the test. DINEN 330:2015-01EN 330:2014(E)6 1 Scope This European Standard specifies a method for determining the relative protective effectiveness against fungal decay of a wood preservative applied to wood in combination with a subsequent surface coating, exposed

36、 to the weather and out of contact with the ground. The effectiveness is evaluated relative to a reference wood preservative. The method is applicable to the testing of commercial or experimental preservatives applied to non-durable timbers by methods appropriate to commercial practice and subsequen

37、tly coated with a specified coating system. The method is applicable to products and processes used individually or in combination to prevent the development of decay in the wood. The method is also appropriate for factory finishing systems which include wood protection and wood preservation claims.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amen

39、dments) applies. EN 1001-2, Durability of wood and wood based products - Terminology - Part 2: Vocabulary EN 335, Durability of wood and wood-based products - Use classes: definitions, application to solid wood and wood-based products 3 Terms and definitions For the purposes of this document, the te

40、rms and definitions given in EN 1001-2 apply. 4 Principle Jointed samples (L-joints) are treated, assembled, coated and placed out of contact with the ground and exposed to the normal environmental and ecological factors which affect coated wood so exposed in practice. The organisms that colonize su

41、ch units invade in their natural sequence of moulds, blue stain fungi, soft rot fungi and basidiomycetes. Colonization by basidiomycetes, as shown by the presence of visible decay, is assessed at least annually by visual inspection of the L-joints after they have been dismantled. In addition, period

42、ically, sets of samples are examined after dismantling and sawing along the grain of the L-joint assemblies to reveal their internal condition. These data are compared with those generated using a reference material and untreated samples to assess relative performance. It is recommended that the rep

43、licates for non-destructive inspection continue to be exposed beyond the minimum 5 year period, preferably until failure. NOTE Inspection after sawing is necessary because application by processes such as double vacuum and superficial (surface) application does not result in complete penetration of

44、the L-joint members. The untreated core of the samples, therefore, can show internal decay before it becomes visible on the surface within the joint. DINEN 330:2015-01EN 330:2014 (E) 7 5 Materials 5.1 End-seal compounds 5.1.1 Preservative resistant end-seal A material resistant to the penetration of

45、 the reference and test preservative solutions (or separate materials for each). 5.1.2 Weatherproof end-seal A material that prevents water entry into the test specimen and remains effective for the duration of exposure of the test specimen to the weather. NOTE Two coats of an epoxy-resin / pitch co

46、mpound have been found to be suitable. 5.2 Reference coating Opaque high gloss, gloss or semi-gloss solvent borne alkyd paint applied in 2 or 3 coats to give a dry film build of (50 5) m or an opaque water borne acrylic paint applied in 1 or 2 coats to give a dry film build of 110 m -120 m when meas

47、ured by method 4A (microscope method) of ISO 2808. If a particular coating system is specified by the supplier of the test preservative to be an integral part of the protection system, this shall be used in conjunction with the test preservative, instead of the reference coating. Details of the coat

48、ing system used shall be given in the test report including the number of coats and the contribution each coat makes to the coating system used, e.g. primer function. 5.3 Reference preservative Containing hexabutyldistannoxane (bis(tri-n-butyltin) oxide) as the active ingredient and with the followi

49、ng composition: Hexabutyldistannoxane minimum mass fraction of 1 % (mass fraction 95 % active ingredient); Aliphatic neutral hydrocarbon resin mass fraction of 5 %; Hydrocarbon solvent mass fraction of 94 %, (distillation range 160 C to 215 C; aromatic content mass fraction 10% from the median (8.4) Dry in freely ventilated conditions (8.5.1) unless the supplier specifies otherwise Assemble the L-joints and apply the coating where relevant (8.5.2) Apply permanent labels (8.5.3) Apply weather resistant end-seal (8.5.4) Break
