16、hnical Committee CEN/TC 193 “Adhesives“, the secretariat of which is held by AENOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2001, and conflicting national standards shall be withdr
17、awn at the latest by October 2001. This European Standard supersedes ENV 1965-1:1995. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,

19、esent European standard describes a method to determine the ability of a liquid adhesive to corrode a copper substrate under heat ageing conditions. Temperatures and ageing periods are chosen to ensure the maximum differentiation between the corrosivity of different adhesives and are not intended to
20、 represent any particular service condition. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated r
21、eferences, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 923Adhesives - Terms and de
22、finitions ISO 6958Wrought copper and copper alloys - Drawn rectangular bars - Dimensions and form tolerances. 3 Terms and definitions For the purposes of this standard, the terms and definitions given in EN 923 and the following terms and definitions apply: 3.1 corrosion destructive attack on metals
23、 which can be chemical or electrochemical in nature NOTEThe 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, as far as practicable, free from me
24、tallic 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 and the extent of tarnishing and/
25、or corrosion on the basis of discolouration. 5 Products and materials 5.1 Solvent Any sulfur free, hydrocarbon based solvent, which has been shown to cause no discolouration of the abraded copper substrate at 50 C is suitable. 5.2 Copper substrate, plate Rectangle 12 mm ? 2 mm, ISO 6958 E-Cu F30, pr
26、oduced by electrolysis.

27、 Cotton wool 6 Procedure 6.1 General Use a minimum of three copper plates for each evaluation. 6.2 Preparation of the copper substrate Lay the abrasive cloth or emery paper on a flat surface and wet it with the solvent. Place the copper plate on top on this and cover with the filter paper, to ensure
28、 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 beginning with the edges and finishing with
29、 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 with a piece of cotton wool which has been
30、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 immerse the copper plate in a shallow dish of th
31、e 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 that the test repeated if, during any of the a
32、bove 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 ; or if the appearance of the edge of the plate is significantly different from that of the face. 1) Grade defined by Fdration Europenne des

A lot of red and green shimmer (Butterfly) but no grey. 4CorrosionTransparent black or dark grey or brown with the “Butterfly“ with a slight gree

Shiny or pitch black. 8 Report The test report shall include : a) a reference to this part of European standard ; b) type and designation of the product tested ; c) description of the copper plate preparation procedure ; d) description of the type and thickne
37、ss of the copper plates ; e) corrosion/discolouration grade ranking ; f) details of any operations not specified in this part of the European standard together with details of any events likely to have had had an effect on the results.
