14、1Scope This standard specifies a test method for the determination of the resistance of geotextiles to abrasion using a sliding block. After abrasion the loss in tensile properties is determined. The method is applicable to woven and nonwoven geotextiles and geotextile-related products. 2Normative r

19、radant with specified surface characteristics. Under controlled conditions of pressure and abrasive action, the abradant is moved along on a horizontal axis with a uniaxial motion. Resistance to abrasion is expressed as the percentage loss of tensile strength of the test specimen. NOTE: Changes in o

21、 -,-,- ISO 13427:1998(E) ISO 2 5 Apparatus 5.1 Abrasion tester (see figure 1), having the following essential parts: 5.1.1 Balanced head and block assembly The assembly shall consist of two parallel, smooth plates 50 mm x 200 mm, one of which moves with a reciprocating motion. The frequency of the r
22、eciprocating plate shall be adjustable to a maximum of 90 double strokes per minute. The stroke length shall be (25 1) mm. The second plate is rigidly supported by a double-lever assembly to provide free movement in a direction perpendicular to the reciprocating plate. This plate is held stationary
23、during the test and is well balanced so that a vertical load can be maintained by means of dead weights. Both plates are equipped with clamps at each end to hold the test specimen and the abrading medium. The clamps have rough surfaces to prevent slippage of the specimen or the abrading material dur
24、ing the test. 5.1.2 Indicator An indicator for counting the number of cycles (1 cycle = 1 double stroke) shall be used. 5.1.3 Weights Weights shall be used for applying the vertical load to the specimen. 6 Test specimens Take a sample in accordance with EN 963. From the laboratory sample prepare fiv
25、e test specimens. Cut rectangular specimens (50 x 600) mm 1 mm and mark the machine direction. For the tensile test, cut two specimens of 300 mm length. Take one specimen for abrasion and one for reference. If the material to be tested is known to have different characteristics on the two sides (e.g
26、. physical characteristics or as a consequence of the manufacturing process), then the complete test shall be carried out separately on each face using 10 specimens; the report shall include details of this extension of the test procedure, and separate results for each side shall be given. 7Conditio
27、ning Condition the test specimens in a standard temperate atmosphere defined in ISO 554 until the change in mass between two successive weighings made at intervals of not less than 2 h does not exceed 0,25 % of the mass of the test specimens.

29、ting as described in clause 7. 8.2 Place the specimen to be tested in the upper (stationary) plate und secure it by means of the clamp at each end of the plate. Place the abrading medium on the lower (reciprocating) plate and secure it by means of the clamp at each end of the plate. Use emery cloth
30、with abradant P 100 in accordance with ISO/DIS 6344-2. NOTE: When testing geotextiles, the specimen can be secured to the stationary plate by using a touch and close fastener or some other type of non-penetrating adhesive. 8.3 Lower the top plate onto the bottom plate by releasing the support pin fo
31、r the top plate. Be sure the abrading medium and the specimen are properly aligned. 8.4 Load the pressure (top) plate with a (6 0,01) kg load, including the top plate. 8.5 Start the tester and operate at a maximum frequency of 90 cycles per minute. 8.6 Operate the tester at the specified frequency f
32、or 750 cycles, or until the specimen ruptures. NOTE: If a specimen ruptures before the specified number of cycles is reached, the rupture of the specimen and the number of cycles completed at the time of rupture are reported. 8.7 If the specimen or the abrading material slips in the clamps, discard
33、the specimen and test another specimen after adjustments are made. 8.8 Replace the abrading medium after each test. 8.9 Carry out the tensile test according to prEN ISO 13934-1. 9 Calculation and expression of results. Determine the loss in tensile strength and report to the nearest 1 %: Loss in ten
34、sile strength (in %) = 100 (A - B)/A where: A is the tensile strength of the reference specimen, B is the tensile strength of the abraded specimen. Calculate the average loss in tensile strength and the coefficient of variation for the series of five specimens. Copyright International Organization f
