This European Standard
17、 shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2004 and conflicting national standards shall be withdrawn at the latest by January 2004. In this European Standard the annexes A and B are normative. This docume
18、nt supersedes EN 1443:1996. This European Standard has been revised in conjunction with AFERA (Association of European self Adhesive tapes Manufacturers) in Europe and PSTC (Pressure Sensitive Tape Council) in USA with the purpose to produce a standard which will be acceptable in due course by ISO.
19、Key changes from EN 1939:1996 are: ? steel plates are revised to readily available, industry standard steel with a smoother surface finish; ? a lighter, rubber coated roller; ? dwell time before testing is more realistically specified at one minute; ? test data from the revised test will be generall
20、y lower than from EN 1939:1996. NOTEThe lower value obtained by the new method does not reflect any change in product performance. The scope of the standard has also been extended to include: ? peel adhesion at an angle of 90; ? peel adhesion of a liner to an adhesive tape. According to the CEN/CENE
21、LEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Sl

23、self adhesives tapes. Annexes A and B specify further variations in the testing protocol according to specific conditions. This European Standard contains: ? Method 1:Self adhesive tapes Measurement of peel adhesion from stainless steel at an angle of 180 ; ? Method 2:Self adhesive tapes Measurement
24、 of peel adhesion from its own backing at an angle of 180 ; ? Method 3:Self adhesive tapes Measurement of peel adhesion of double sided and transfer tapes at an angle 180 ; ? Method 4:Self adhesive tapes Measurement of adhesion of the liner to an adhesive tape at an angle of 180. Together with ? Ann

27、sessing the uniformity of the adhesion of a given type of self adhesive tape. The assessment may be within a roll of tape, between rolls or between production lots. NOTE 2Variations in the tape backing and adhesive affect the response. Therefore these methods cannot be used to pinpoint the specific
28、cause(s) of non uniformity. NOTE 3These test methods may not be appropriate to test tapes having either relatively stiff backings, stiff liners or backing showing high stretch at low forces. These characteristics will result in a high variability for the test response which is not a true indication
29、of the real nature of the adhesive bond.

These
30、normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, 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
31、references the latest edition of the publication referred to applies (including amendments). EN 10088-2, Stainless steels - Part 2: Technical delivery conditions for sheet/plate and strip for general purposes. EN 12481:2000, Self adhesive tapes - Terminology. 3 Terms and definitions For the purposes
32、 of this European Standard the terms and definitions given in EN 12481:2000 and the following terms and definitions apply. 3.1 peel adhesion force required to peel a strip of adhesive tape from a specified substrate at a specified angle and speed 3.2 open side (adhesive) surface of the adhesive on a
33、 double sided tape which is exposed on normal unwinding or separation of the first liner 3.3 closed side (adhesive) surface of the adhesive on a double sided tape which normally remains in contact with the release liner on normal unwinding or separation of the first liner 3.4 transfer tape adhesive
34、tape having two available pressure sensitive surfaces without the need for a carrier and with a release liner separating the adhesive surfaces. The adhesive may contain reinforcing material 4 Significance and use These test methods are tools for quality control use. Given specific self adhesive tape
35、 and a requirement in terms of the minimum or maximum value expected for this tape, the data from the test can be used in conjunction with acceptance criteria. Test methods 1, 2, 3, and Annexes A and B can show the relative bond strength of a given tape to one or more surfaces (material and texture)
36、 as compared to the standard stainless steel panel. Substitution of representative samples of materials in question for the standard steel panel would suffice to do this. Test methods 1, 2, 3, and Annexes A and B cannot be used to compare two self adhesive tapes of the same type but of different man
37、ufacture for their ability to adhere to a surface. This is because the measured peel force is not normalised for a fixed area of stress. The area under stress varies with backing stiffness and adhesive rheology (firmness). Two different tapes seldom agree in these properties. Test method 4 can show
38、the amount of force required to remove a liner that covers the adhesive side of a tape at a specified peel rate. The force will be different at other peel rates. These test methods may not provide design information as there is usually no direct relationship between peel adhesion and any functional
39、requirement.

40、ired to remove at an angle of 180 an adhesive tape which has been applied to a stainless steel panel. A length of adhesive tape is applied to a standard plate which is then fixed vertically in one clamp of a tensile testing machine. The other clamp of the machine pulls the free end of the adhesive t
41、ape at an angle of 180 to the plate. The adhesive strength is measured by the force required to peel the adhesive tape continuously from the plate, the line of separation being perpendicular to the direction of the applied force. 5.2 Materials 5.2.1Absorbent cleaning material: surgical gauze, cotton
