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 information about Standards can be found by visiting the Standa

(c) Steel roller (see Figure 1) Of diameter 80 5 mm and width 45 1 mm covered with rubber approximately 6 mm thick, and having a durometer hardness of 80 5 Type A degrees (in accordance with AS 1683.15.2). NOTE: The mass o

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 (o
19、ne 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 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. (e) Absorbent paper (f) Fr

21、e roll shall be conditioned at 23 5C and 50 5% relative humidity for 24 1 h prior to testing. The test specimen shall be a minimum of 250 mm long. 7 PROCEDURE The procedure shall be as follows: (a) Dispense the isopropynol (3.1) on the clean stainless steel panel (4(b) and wipe until dry with the fr
22、esh absorbent cleaning material (4(f). Repeat this procedure for a total of three washes. Discard cleaned panels showing stains, discoloration or scratches. Avoid contact of the panel surface with the fingers. NOTE: Either surgical gauze or untreated paper tissue may be used. (b) Take test specimens
23、 from a freely rotating conditioned roll, the minimum width of which shall be 6 mm, by manually unrolling the roll radially and discarding the outer three laps of the roll. NOTE: The speed of removal of the test specimen from the roll is operator-dependent. Usually, a speed of approximately 300 mm/s
24、 is attained. (c) Where the width of a roll is 25 mm wide or less, use the test specimens direct. (d) Where a roll is greater than 25 mm wide, cut the roll using the specimen cutter, to a width of 25 mm. (e) Apply the specimen, adhesive side down, to the centre of the surface of the stainless steel
25、panel and parallel to its long axis, leaving sufficient of the specimen extending beyond the panel to be accommodated in the tensile testing machine. Do not allow the adhesive surface to come in contact with the fingers and other foreign objects, or to become contaminated with dust. NOTE: Where a te
26、st specimen is taken from a roll less than 25 mm wide, cut other strips from the same roll and apply these strips parallel and adjacent to the test specimen to provide a total width of approximately 25 mm, for rolling purposes only.

Ensure that no pressure additional to the mass of the roller is applied and that no air bubbles are entrapped. (g) Measure
28、and record the width of the specimen to the nearest 0.5 mm. (h) Immerse the panel in the distilled water at a temperature of 23 5C for a period of 2 h 5 min. (i) Remove the panel from the water and remove surplus water using the absorbent paper. (j) Double back the free end of the specimen at an ang
29、le of 180 degrees and peel off approximately 25 mm of the specimen from the panel at the doubled end. (k) Attach the exposed (doubled) end of the steel panel to one jaw or carriage of the tension testing machine, and attach the free end of the specimen to the other jaw or carriage of the tension tes
