The methods described in this standard are suitable for the following and other applications: - assessing the usability and quality of adhesives for wood and derived timber products; - classifying these
21、adhesives into the durability classes D1 to D4 of EN 204 (thermoplastic adhesives) and C1 to C4 of EN 12765 (thermosetting adhesives); - assessing effects on the bond strength resulting from the bonding conditions chosen, the various conditioning sequences and the treatment of the test pieces before
22、 and after bonding; Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 03 09:24:04 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 205:2003 (E) 5 1 Scope This European Standard describes tests for adhesives for wood and derived timber products for the assessment of their resistance to hot and cold wa
