CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and

    15、bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibili

    16、ty of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions.

Knowledge of the flagging is useful in determining whether the adhesion of the adhe

    21、sive tape to a backing of the same adhesive tape is adequate for applications where unwinding could occur. The flagging may occur under normal conditions, during the curing cycle of thermosetting adhesives or during immersion in liquids. 2 Definition For the purposes of this standard, the following

    22、definition applies. flagging A peeling away from the surface of tape backing of the end of a length of tape, particularly in a spiral wrap application. 3 Principle A length of adhesive tape is wound upon itself round a thin rod with one-quarter turn overlap. After the prescribed time and conditions,

    23、 any lifting of the end is examined and, where necessary, measured. 4 Apparatus 4.1 A simple winding jig, designed to hold a rod at each end, with a means of rotating the rod so that the test piece may be wound thereon. The winding jig shall be attached to a rigid support with the rod held in a hori

    24、zontal position. 4.2 Rods, of any suitable metal or glass, of 6 mm or 12 mm nominal diameter. 4.3 Attachable masses, of 100 g, 200 g, 300 g and 400 g. 4.4 A suitable method of measuring 2 mm to the nearest 0,5 mm. 5 Test pieces Three strips of adhesive tape at least 100 mm long are removed from the

    25、roll by pulling radially, at a rate of approximately 300 mm/s, at intervals of 300 mm. If the width of the adhesive tape is greater than 12 mm, the test piece shall be cut out of the middle of the adhesive tape to a width of 9 mm. The test piece shall be cut with a sharp tool to avoid tearing the ed

    26、ges. NOTE. It is important to protect the adhesive surface from dust and to avoid touching it with the fingers or any other foreign object. 6 Procedure 6.1 Standard test conditions The test shall be carried out at 23 C 2C and 50 % 5 % relative humidity. 6.2 Preparation of rods Prepare three rods acc

    27、ording to the following procedure: Mount a rod of 6 mm diameter (unless otherwise specified) in a horizontal position in the jig. Attach a mass in the ratio of 400 g for 12 mm adhesive tape width, e.g. 300 g for 9 mm width, to one end of the adhesive tape test piece. The test piece is held by the ot

    28、her end so that it is vertical and the adhesive side is brought into contact with the side of the rod. (See figure 1.) Rotate the rod through 90 until the original point of contact, A, of the test piece with the rod is at the top. (See figure 2.) Cut the test piece with a sharp tool at this point, l

    29、eaving the mass suspended. The rod is then rotated one complete turn. Remove the mass and cut the test piece at D by placing a sharp tool tangentially to the rod (see figure 3) and tearing the test piece against the tool. This gives an overlap of one-quarter turn, i.e. 90. 6.3 Determination of flagg

    30、ing 6.3.1 Flagging at the standard conditions Condition the prepared test piece in the vertical position for 7 days at 23 C 2 C and 50 % 5 % relative humidity. 6.3.2 Flagging after thermosetting of adhesive tapes Condition the prepared test piece in the vertical position at the temperature and for t

    31、he time prescribed by the manufacturer or in the relevant specification sheet. 6.3.3 Flagging after immersion in liquids The prepared test piece, cured if necessary, shall be totally immersed in the vertical position in the liquid for 15 min at 23 C 2 C. Thermosetting adhesive tapes shall be cured f

    32、or the time and at the temperature prescribed, and shall be allowed to cool to 23 C 2 C before immersion in the liquid. The liquids for immersion shall be agreed between the manufacturer and the customer.Page 4 EN 12035 : 1996 BSI 1997 Figure 1 Figure 2 Figure 3 Figure 4 Figures 1, 2, 3 and 4. Flagg

    33、ing test Preparation of test piece 7 Expression of results Measure the flag, i.e. the length of adhesive tape unwound (see figure 4) to the nearest 1 mm. Should uneven flagging occur, the greatest distance is measured. Record the median value of the three readings as the amount of flagging. 8 Test r

    34、eport 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) if necessary, the composition or the nature of the liquid used for the test; e) the results obtained; f) any

    35、operation not specified in this European Standard which may influence the results.blankBSI 389 Chiswick High Road London W4 4AL | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
