14、33 GMT+00:00 2006, Uncontrolled Copy, (c) BSI OSI 9283002:6)E( ISO 3002 r llAithgs reservde iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carr
15、ied out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
16、ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare Internat
17、ional Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the e
18、lements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8296 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products. This second edition cancels and replaces the first edition (I
19、SO 8296:1987), of which it constitutes a minor revision which included the correction of 4.1 to simply specify a “wire bar” (rather than “wire bar No. 2” as in the first edition) and correction of the area over which the liquid is spread in 7.2, second paragraph, from to . 20 cm2 6 cm2 BS ISO 8296:2

21、reservde 1 Plastics Film and sheeting Determination of wetting tension 1Scope 1.1This International Standard specifies a method for determining the wetting tension of surfaces of plastic film and sheeting in contact with drops of specific test solutions. 1.2The ability of plastic films to retain ink
22、s, coatings, adhesives, etc., is primarily dependent on the character of their surfaces, and can be improved by one of several surface-treatment techniques. These same treatment techniques have been found to increase the wetting tension of a plastic film surface in contact with mixtures of solvents.
23、 It is therefore possible to relate the wetting tension of a plastic film surface to its ability to accept and retain inks, coatings, adhesives, etc. The measured wetting tension of a specific film surface can only be related to acceptable ink, coating, or adhesive retention through experience. Wett
24、ing tension, in itself, is not a completely acceptable measure of ink, coating or adhesive adhesion. 1.3Any contamination of the film surface and any trace of surface-active impurities in the liquid reagents may affect the wetting tension. It is therefore important that the portion of the film surfa
