21、dry and wet strengths of bond-lines measured under specified conditionsafter various conditioning treatments.For special applications, further tests that do not fall within the scope of this standard may be applicable.The adhesives described in this standard are suitable for the bonding of furniture
22、 and interior structures, panelling,doors, windows, stairs etc made of wood or derived timber products.This standard does not define the temperature resistance of bond-linesNOTE Thermoplastic resin are described in EN 923 as: polymer or copolymer, capable of being softened by heating andhardened by
23、cooling.2 Normative referencesThis European Standard incorporates by dated or undated reference, 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 r
