23、sion destructive attack on metals which can be chemical or electrochemical in nature NOTE The described method measures essentially only the chemical attack. The electrochemical contribution is eliminated as far as possible by ensuring that there is no electrolyte and that the copper substrate is, a
24、s far as practicable, free from metallic impurities which can result in the formation of a galvanic cell. 4 Principle An abraded and polished copper substrate is coated with a thin film of the liquid adhesive and then aged for 24 h in dry heat at 50 C or 100 C. Following this the surface is examined
25、 and the extent of tarnishing and/or corrosion on the basis of discolouration. 5 Products and materials 5.1 Solvent. Any sulfur free, and water free, hydrocarbon based solvent, which has been shown to cause no discolouration of the abraded copper substrate at 50 C is suitable. The solvent should be
26、able to dissolve the uncured adhesive 5.2 Copper substrate, plate. Recommended cross section 12 mm 2 mm, ISO 6958 E-Cu F30, produced by electrolysis.

Place the copper plate on top on this
28、 and cover with the filter paper, to ensure that the copper surface is protected from contamination by fingers. Rub the copper plate in a criss-cross pattern against the abrasive material until a uniform abraded surface is achieved. It is necessary to abrade all six plane surfaces of the test plate
29、beginning with the edges and finishing with the faces. Following this abrasion, store the copper plate in solvent. 6.3 Determination Remove the copper plate from the solvent, handling only with the tweezers, and place on a clean glass plate. Coat the copper plate with the liquid abrasive and abrade
30、with a piece of cotton wool which has been moistened with a drop of solvent. Finally, polish vigorously with clean, dry, cotton wool, repeating the polishing with fresh pieces of cotton wool until one remains clean and white following polishing. On completion of the final abrasion, immediately immer
31、se the copper plate in a shallow dish of the adhesive, again handling with tweezers, and place in a oven at 50 C or 100 C for 24 h. Remove the copper plate from the dish with the tweezers and carefully wash in solvent to remove uncured material, then dry it with the filter paper. It is essential tha
32、t the test is repeated if, during any of the above procedures or testing, the copper plate: a) is touched by fingers; b) comes into contact with water; or c) comes into contact with any other material; d) or if the appearance of the edge of the plate is significantly different from that of the face.
