This information is given for the convenience of users of this standard and does not constitute an endorsement by CEN of this product type. 1 Scope This standard specifies the method to measure, under specified test conditi
29、ons, the force required to remove an adhesive tape which has been applied to a standard metal surface. This European Standard specifies the method of measurement, under specified test conditions, the force required to remove an adhesive tape which has been applied to: a standard metal surface; from
30、its own backing; from stainless steel at low temperature; from stainless steel of double sided adhesive tapes; and from stainless steel of an adhesive transfer tape. NOTE. For the purpose of facilitating the understanding of this standard, it has been divided into five separate test methods. 2 Defin
31、ition For the purposes of this standard the following definition applies. peel adhesion The force required to peel a strip of tape from a specified substrate at a specified angle and speed. 3 Principle A length of adhesive tape is applied to a standard plate which is then fixed vertically in one cla
32、mp of a tensile testing machine. The other clamp of the machine pulls the free end of the adhesive tape 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 di
33、rection of the applied force. 4 Materials 4.1 Diacetone alcohol. 4.2 Lint free cotton wool or tissue. 4.3 One of the following solvents: methanol; methyl ethyl ketone; acetone; toluene. Solvents shall be of general purpose chemical grade. 5 Apparatus 5.1 Tensile testing machine, with the following c
34、haracteristics: the force shall be indicated with a maximum error of 2 %; the speed of the moveable clamp shall be 300 mm/min30 mm/min; the scale shall be such that the readings obtained are between 15 % and 85 % of the complete scale; the clamps shall be serrated to prevent slipping or tearing of t
35、he tape; if a pendulum machine is used, ensure that the pendulum can swing freely. 5.2 Stainless steel plates1) These shall be perfectly flat, 200 mm long 3 50 mm wide and 2 mm thick. They shall be made from polishing quality stainless steel of a Brinell hardness ranging from 130 to 200 (see ISO 650
36、6) and comprising the following constituents: carbon 8 %; chromium 17 %. The testing surface of the plate shall first be polished to a mirror finish. It shall then be roughened with abrasive grit2). The abrasion lines shall be parallel to the long edge of the plate. The plate shall be graduated on t
37、he long edges with five short marks spaced 30 mm apart, the first being 50 mm from one end. (This is referred to as the starting end in 7.3.2.) Check that the surface conforms to the following conditions by five transverse measurements in the area between two imaginary lines 10 mm on each side of th
38、e longitudinal axis of the plate: mean range between 0,05 mm and 0,40 mm; maximum depth less than 4 mm. Sampling length (of abraded area of test plate) is 0,8 mm; the evaluation length of five transverse samples provides the abraded area required to cover all possible variables in surface rugosity.
39、NOTE. A full explanation of these terms will be found in ISO 468 and ISO 4287-1. Between each test, the plates shall be kept in such a way as to avoid any accidental scratching which may modify the surface condition. 5.3 Polished cylindrical metal roller This shall have a diameter of at least 50 mm
40、and a mass corresponding to 2 kg/cm width of adhesive tape under test.

41、t sample and test pieces Condition the sample roll for 24 h at 23 C2 C and 50 %5 % relative humidity. Discard the three outer turns of adhesive tape from the roll before taking test pieces. Perform the test on test pieces 400 mm long and the same width as the adhesive tape. Take five or ten test pie
42、ces as required by the test. For widths greater than 25 mm, a test piece 25 mm wide shall be cut longitudinally from the adhesive tape. The cutting shall be carried out by means of a razor-blade or any other suitable instrument. It shall always be effected so that the adhesive surface never contacts
43、 other surfaces before application to the test plate. Cutting shall never be carried out with the adhesive tape already applied to the test plate, so as not to mark the plate for subsequent tests. 7 Procedure 7.1 Standard test conditions The test shall be carried out at 23 C2 C and 50 %5 % relative
44、humidity. 7.2 Preparation of plate Wipe the test surface of the plate with a fresh piece of cotton wool or tissue saturated with diacetone alcohol. Dry the plate with fresh cotton wool, then wipe the test surface with a fresh piece of cotton wool saturated with one of the solvents given in 4.3. Dry
45、the plate with fresh cotton wool, then repeat for a total of three cleaning operations with this solvent. Maintain the plate at a temperature of 23 C2 C for at least 5 min before proceeding. In order to obtain consistent results, a new plate shall be cleaned at least 10 times before use. 7.3 Peel ad
46、hesion from stainless steel 7.3.1 Application of the test piece to the plate Take five test pieces by unrolling the conditioned roll radially at a speed of approximately 300 mm/s and then apply them in the manner described below, within 15 s, in the standard test conditions. Apply the test piece pro
47、gressively by gentle longitudinal finger strokes in such a way that the formation of air bubbles between adhesive tape and plate is avoided, without, however, exerting appreciable pressure on the adhesive tape. The test piece shall be centred on the plate such that the edge of the test piece is para
48、llel to the long edge of the plate. Pass the roller over the surface of the adhesive tape, to and fro, twice in each direction, at a speed of approximately 10 mm/s. Leave the adhesive tape adhered to the plate for 10 min in the standard test conditions and then test as described below. 7.3.2 Strippi
49、ng the test piece from the test plate Peel off about 25 mm of the adhesive tape from the starting end of the plate, the line of separation being perpendicular to the axis of the test piece. Fix the starting end of the plate in one clamp of the tensile testing machine. Fold back the free end of the adhesive tape and fix it in the other clamp so that the non-adhesive surfaces are almost in contact and exactly aligned. Ensure that the two surfaces remain perfectly
