EN ISO 9864:2005 (E) 4 1 Scope This document specifies a method for the determinati
17、on of mass per unit area of geotextiles and geotextile-related products for identification purposes and for use in technical data sheets. The method is applicable to all geotextiles and geotextile-related products. 2 Normative references The following referenced documents are indispensable for the a
18、pplication of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

19、g and preparation of test specimens (ISO 9862:2005). 3 Principle The mass per unit area is calculated by weighing square or circular specimens of known dimensions cut from positions distributed over the full width and length of the sample. 4 Procedure 4.1 Specimens Cut no less than ten specimens in
20、accordance with EN ISO 9862 to a nominal size of 100 cm, using a die. Cut the specimens in such a way that they are representative of the material to be tested. Measure the specimens to an accuracy of 0,5 %. If the structure of the product is such that a 100 cm specimen is not representative, it may
21、 be necessary to use a larger specimen size in order to achieve the necessary accuracy of measurement. Geotextile-related products with relatively large mesh sizes such as geogrids or geonets shall be cut half way between two links of the constituent elements. A specimen shall include at least 5 con
22、stituent elements in both directions. The area of the specimen shall be individually determined for each specimen. Condition the specimens in accordance with ISO 554 for a period of 24 h unless it can be shown that the results are not affected by omitting this procedure. 4.2 Weighing Weigh each spec
23、imen to an accuracy of 10 mg. EN ISO 9864:2005(E) 5 5 Expression of results Calculate the mass per unit area Aof each specimen, expressed in grams per square metre, using the equation A m 000 10 A = where: m is the mass of the specimen, in g; A is the area of the specimen, in cm 2 . Calculate the me
24、an mass per unit area, rounding the result to the nearest gram per square metre, and the coefficient of variation. 6 Test report The test report shall include the following particulars: a) statement that the test was performed in accordance with this document; b) number of specimens tested; c) condi
25、tioning atmosphere used; d) in case of a specimen size larger than 100 cm 2 , the size used, and a description (words, sketch or photograph) of the structure; e) mean value of mass per unit area, in grams per square metre; f) coefficient of variation; g) details of any deviation from the specified t
26、est procedure; h) date of the test.
