23、equired to burst an adhesive tape. 2 Normative reference 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 references,
24、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. ISO 2758 Paper Determination of bursting strength 3 Definition
25、For the purposes of this standard, the following definition applies. bursting strength The ability of a tape to resist damage when force is applied perpendicularly to the surface of the tape. 4 Principle A test piece of adhesive tape is subjected to an evenly distributed pressure, usually exerted fr
26、om below by means of an elastic diaphragm, and the bursting pressure is measured. 5 Apparatus Bursting strength tester (Mullen type, or any type complying with ISO 2758), with the following main characteristics. 5.1 Clamping device To allow the test piece to be clamped between two ring-shaped surfac
27、es, with a minimum external diameter of 30 mm, in such a way that no slipping occurs during the test. Throughout the test, the upper clamping ring should remain almost concentric and parallel to the lower clamping ring. 5.2 Elastic diaphragm The elastic diaphragm is maintained between the lower clam
28、ping ring and the framework of the equipment; initially the upper surface of the diaphragm should be at a distance of about 0,2 mm below the clamping plane, so that it is in contact with the test piece from the beginning of the test. The diaphragm should be capable of withstanding any working pressu
29、re likely to be encountered, without permanent distortion. 5.3 Pressure generator This is formed by a device producing an increasing controlled hydraulic pressure under the elastic diaphragm. This pressure is produced by a piston forcing a liquid into a pressure chamber at a constant speed of 95 ml/
30、min10 ml/min (for automatic equipment) or 120 revolutions per minute (for a manual system). A suitable device should enable the pressure generator to be stopped or its direction reversed, at the moment of bursting. A pressure indicator should be provided which records the maximum pressure reached an
31、d to record it even after the pressure gauge has returned to zero. Pressure gauges shall be used for test pressures between 10 % and 75 % of the maximum of their calibrations. 6 Test pieces Condition the rolls for 24 h at 23 C2 C and 50 %5 % relative humidity before testing. Discard the three outer
32、turns of adhesive tape from each roll. Take from each roll five test pieces. The test pieces shall be taken from adhesive tapes with a width in excess of the external diameter of the ring-shaped surfaces. 7 Procedure 7.1 Standard test conditions: The tests shall be carried out at 23 C2 C and 50 %5 %
33、 relative humidity. 7.2 Zero the pressure gauge to be used. Place the test piece on the platen of the machine, adhesive side upwards, taking care to avoid any distortion of the test piece; then tighten it sufficiently to avoid slipping. Apply the pressure until the test piece bursts and record the p
34、ressure at the moment of bursting. Disregard results where a clean break occurs at the edges of the test piece (through excessive clamping or rotation of the clamping rings). Repeat the test on five test pieces. 8 Expression of results The resistance to bursting shall be the average of the results o
35、btained. Express results in megapascals (MPa).
