21、of adhesive tape on a roll. For non-extensible adhesive tapes, the length measured by this method will be the same as the length after unrolling. For extensible adhesive tapes, the length after unrolling will be greater if the adhesive tape is stretched irreversibly by unrolling. It is also possible

22、 for an extensible adhesive tape to measure less after unrolling if stress built in during manufacture recovers after unrolling. This is important for all adhesive tapes with elongation at break of 80 % or greater. Provision is made for either including in or excluding from the total length the leng

23、th of that portion of adhesive tape that is in direct contact with the core. 2 Principle The length is calculated from a measurement of the number of turns of adhesive tape on the roll and a measurement of the outer circumference of the roll of adhesive tape and the outer circumference of the core.

24、3 Apparatus (see figure 1) 3.1 Measuring device which is capable of counting both whole revolutions and part revolutions, and which is continuously driven by a spindle. The spindle carries a suitable locking device, by which means a wedge-shaped shaft to suit the various internal diameters of cores

25、of the rolls of adhesive tape can be quickly fitted. (The wedge-shaped shaft, for example, for a nominal 25 mm internal diameter core, will go from 24,5 mm diameter to 26,5 mm diameter over a shaft length of 50 mm.) 3.2 Measuring tape. A narrow, flexible, steel tape graduated in millimetres. 4 Test

26、piece One roll of adhesive tape. 5 Procedure 5.1 Standard test conditions The test shall be carried out at 23 C 2C and 50 % 5 % relative humidity. 5.2 Measure the circumference in millimetres (C R )of the roll by means of a steel tape, applying the steel tape to the roll like a belt. 5.3 Mount the r

27、oll on the wedge-shaped shaft of the counter. Set the counter to zero and pull the adhesive tape from the roll in a direction perpendicular to the counter spindle. Remove all the adhesive tape from the core and record N, the number of revolutions (to the nearest tenth of a revolution) as read from t

28、he counter when the last layer of adhesive tape has left the core. 5.4 Measure the circumference of the core in millimetres (C 0 ). 6 Expression of results Calculate L, the length of the adhesive tape in metres, as follows: L=( C R + C 0 ) N 2000 If the length of adhesive tape in contact with the co

29、re is not to be included in the total length, then: L=( C R + C 0 ) 2 N 2000 C 0 1000 7 Test report The test report shall include the following information: a) a reference to this European Standard; b) all information necessary to identify the test sample; c) the date of the test; d) the results obt

30、ained; e) any operation not specified in this European Standard which may influence the results.Page 4 EN 12034 : 1996 BSI 1997 Dimensions in millimetres Figure 1.
