(See prEN 1939.) 6.3 Horizontai traverse device (see fig. 1) A simple mechanical device that wiil ensure that the plate moves horizontaly at the rate of traverse of the tensile testmg machine throughout the period of

15、 peeling the adhesive tape at an angle of approximately 90“. This device may consist of a metal section containing two grooves in which the plate can move freely in a horizontal plane. This section shall be fixed rigidly to one clamp, the plate being positioned horizontally and centred with respect

16、to the vertid passing through the two clamps. A convenient way to make the plate move horizontally at the same speed as the moveable clamp is to connect it to a fixture by means of an inextensible wire passing round a pulley attached to the device. The device is designed to produce a theoretical pee

17、l angle of 90“. In practice the angle of peel varies slightly around this figure due to irregularities in the structure of the adhesive mass. The extent of the vanation will also depend on the degree of damping of the tensile testing machine. 6.4 Roller for the application of light pressure This roi

Horizontal traverse device 8 Procedure 8.1 Standard test conditions The test shall be carried out at 23 “C f 2 “C and 50 % f 5 % relative humidity. 8.2 Preparation of plate 7 Test sample and test pieces Use rolls of adhesive tape at least 25 mm wide. Condition the sample roll for 24 hours at 23

20、“C f 2 “C and 50 %f 5 % relative humidity Discard the 3 outer turns of adhesive tape from the roa Take from each roll 5 test pieces. Each test piece shall be 300 to 375 mm long. For widths greater than 25 mm, a test piece 25 mm wide shall be cut longitudinally hm the adhesive tape. The cutting must

21、be carried out by means of a razor-blade or any other suitable instnim ent. It must aiways be effected so that the adhesive surface never contacts 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 n

22、ot to mark the piate for subsequent tests. Wipe the test surface of the plate with a fresh piece of cotton wool or tissue saturated with diacetone dcohol. 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 6.

23、3. Dry the plate with fresh cotton woob then repeat for a total of three cleaning operations with this solvent. Maintain the plate at a temperature of 23 “C f 2C for at least 5 min before proceeding. In order to obtain consistent results, a new plate must be cleaned at least ten times before use. 8.

24、3 Application of the adhesive tape to the plate Place the piate on an inclined plane having a slope of i (mahg an angle of 1139 with the horizontal). Remove the test piece radiaily from the roll at an approximate speed of 300 mm/s, then apply it immediately to the plate in its sloping position. Adhe

25、re the end of the test piece to the middle of the upper edge of the stainless steel plate. Then place the roller on the back of the adhesive tape and hold the other end of the adhesive tape in a vertical pition so that the roller rests in the loop so formed. Allow the roller to travel down the slopi

26、ng plane, thus applying the adhesive tape to the piate, at an approximate speed of 25 mm/s. Take care to ensure that the edges of the adhesive tape are parallel to those of the plate.
