20、 printed by approved subscription and freemailing clients of the SABS .Page 5EN 12765:20011 ScopeThis European Standard classifies thermosetting resin based wood adhesives for non-structural applications intodurability classes C1 to C4 based on the dry and wet strengths of bond-lines measured under
21、specified conditionsafter various conditioning treatments.For special applications, further tests, which do not fall within the scope of this standard, could be applicable.The adhesives described in this standard are suitable for the bonding of furniture and interior structures, panelling,doors, win
22、dows, stairs etc made of wood or derived timber products.NOTE Thermosetting resin is defined in EN 923 as: monomer, polymer or copolymer, which when cured, changes into asubstantially infusible and insoluble product.2 Normative referencesThis European Standard incorporates by dated or undated refere
23、nce, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated

25、Terms and definitionsFor the purposes of this European standard the terms and definitions given in EN 923 and the following terms anddefinitions apply.3.1thermosetting wood adhesiveadhesive whose main constituent is a thermosetting resin and which has been formulated for bonding wood4 Classification
26、An adhesive shall be classified in accordance with Table 1, which gives examples of climatic conditions and fieldsof application in which the bonded member is to be used. The classification shall be based on tests on thin bond-lines except when gap-filling properties are claimed, in which case it sh
27、all be based on tests using both thin andthick bond-lines as defined in EN 205.SANS 10183-3-3:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .Page 6EN 12765:2001Table 1 Description of durability classesDurabilityclassesExamples of climati

30、ethodThe adhesive shall be tested in accordance with EN 205 and as follows:a) either thin, or both thin and thick bond-lines shall be tested as appropriate (see clause 4);b) the tests shall be performed using the appropriate conditioning sequence given in Table 2;c) the individual values and the mea
31、n value for 10 valid test pieces for each conditioning sequence test shall berecorded.The standard atmosphere used as a control climate is either (20 2) C and (65 5)% relative humidity (rh), (20/65),or (23 2) C and (50 5)% relative humidity (rh),(23/50).6 RequirementsWhen tested in accordance with E
32、N 205, the mean strength of an adhesive shall:a) for thin bond-lines conform to the values shown in Table 2;b) for thick bond-lines, when required, be not lower than 80 % of the values shown in Table 2;NOTE The values given in Table 2 are comparative values and should not be used as a basis for calc
