To maintain their currency, all Standards are periodically reviewed,
4、 and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased. Detailed
5、 information about Standards can be found by visiting the Standards Web Shop at .au and looking up the relevant Standard in the on-line catalogue. Alternatively, the printed Catalogue provides information current at 1 January each year, and the monthly magazine, The Global Standard, has a full listi
6、ng of revisions and amendments published each month. Australian StandardsTM and other products and services developed by Standards Australia are published and distributed under contract by SAI Global, which operates the Standards Web Shop.

13、sBreaking strength 1 SCOPE This Standard specifies the method for determining the breaking strength of pressure- sensitive adhesive tape. 2 REFERENCED DOCUMENTS The following documents are referred to in this Standard: AS 2193 Calibration and classification of force measuring systems 2313 Methods of
14、 test for single sided and double sided pressure-sensitive adhesive tape 2313.2.2 Method 2.2: Physical propertiesElongation 3 DEFINITIONS For the purpose of this document, the following terms and definitions apply. 3.1 Elastic elongation Tapes that exceed 200% elongation are considered to be elastic
15、. 3.2 Non-elastic elongation Tapes with elongation less than 200% are considered to be non-elastic. 4 APPARATUS AND MATERIALS The following apparatus is required: (a) Tensile testing machine The tensile testing machine shall have a rate of travel 300 10 mm/min of the moving jaw or carriage. The init
16、ial clear spacing between the machine jaws shall be 125 mm. The calibration of the tensile testing machine shall comply with Grade B of AS 2193. (b) Specimen cutter Consisting of a 25 mm thick, 200 mm long and 25 mm wide aluminium bar stock. The edges for about 125 mm from one end shall be rounded s
17、lightly to form a handle. The width of the bar for 75 mm from the opposite end shall be narrowed to exactly 25 mm minus the thickness of a single razor blade (one of two razor blades used as cutting edges). The razor blades shall be held in position using side plates. The end of the cutter shall be
18、cut away at a 45 angle to expose the cutting edge at one end of the blades. The edges shall be separated by a distance of 25 0.25 mm. 5 TEST CONDITIONS Testing shall be conducted at 23 5C and 50 5% relative humidity.

19、s Australia .au 6 PREPARATION OF TEST SPECIMENS The roll, from which the test specimens are to be taken, shall be conditioned at 23 5C and 50 5% relative humidity for 24 1 h prior to testing. The test specimen shall be at least 250 mm long for non-elastic backings, and at least 150 mm long for other
20、 types of backings. 7 PROCEDURE The procedure shall be as follows: (a) Take a test specimen from the freely rotating conditioned roll, the minimum width of which shall be 6 mm, by manually unrolling the roll radially and after discarding the outer three laps of the roll. NOTE: The speed of removal o
21、f the test specimen from the roll is operator-dependent. Usually, a speed of approximately 300 mm/s is attained. (b) Where the width of a roll is 25 mm wide or less, use the test specimen direct. (c) Where a roll is greater than 25 mm wide or wider than the width of the jaws of the tension testing m
22、achine, cut the roll using the specimen cutter, to a width of 25 mm. (d) Measure and record the width of the specimen to the nearest 0.5 mm. (e) Clamp the specimen squarely in the jaws of the tension testing machine. (i) Ensure that the spacing between the jaws is 125 2 mm for tapes with non- elasti
23、c elongation and 75 2 mm for tapes with elastic elongation 200% and (see also AS 2313.2.2). (ii) Separate the jaws at a uniform speed of 300 10 mm/min until the specimen breaks. Record the value in newtons. NOTE: Reject those readings obtained where the specimen breaks at, or in, the jaws. (f) Repea
24、t Steps (a) to (e) using another two test specimens taken from the same roll. 8 CALCULATION The average breaking strength for the specimens shall be calculated from the following equation: Rm = W L25 3 m . . . (1) where Rm = average breaking strength, in newtons per 25 millimetre m L = sum of jaw se
25、paration at break, in millimetres W = measured width of specimen Where the results fall below the value specified in the referring Standard, test two further rolls to determine whether the specimens meet the requirements. NOTE: The retest requirements of the method have been introduced to allow for
26、the possibility of an individual roll having been damaged, which could lead to abnormally low figures for the breaking strength.

27、eaking strength of the three specimens taken from the same roll, in newtons per 25 millimetre (N/25 mm) width to the nearest 0.1 N/25 mm.
