40、r-foot surface for testing material of uniform thickness. When testing thinner areas in materials of non-uniform thickness, the reference plate can be as small as the area of the presser-foot, or an alternative supporting device of these dimensions can be used, to ensure full contact with the lower

The part tes
44、ted shall be identified in the test report.Normally, the thickness of geosynthetics is determined by measuring one layer of the product. When two or more layers are used on top of each other in a design, the test may be made in accordance with this part of ISO 9863 with the agreed number of layers i
45、nstead of one.When testing structured geosynthetics, care should be taken to ensure that the results are meaningful for the particular product.The thickness is determined by using the procedure A or C as specified in either 7.2 or 7.4, applying pressures of 2 kPa, 20 kPa and 200 kPa to an accuracy a
46、s stated in Clause 3.If agreed between the interested parties, procedure B, as specified in 7.3, may be used instead of procedure A in 7.2.Other values of pressure may be used if agreed between the interested parties. If a pressure of more than 200 kPa is applied, a new, conditioned specimen shall b

Gently lower the presser-foot applying a pressure of (2 0,01) kPa to the specimen, and note the gauge reading aft
48、er 30 s, unless a longer time is specified.Release the pressure and remove the specimen.7.2.2 Repeat the procedure in 7.2.1 until at least 10 specimens have been tested.7.2.3 Repeat the procedure in 7.2.1 and 7.2.2 using a corresponding number of new specimens and applying a pressure of (20 0,1) kPa
49、.7.2.4 Repeat the procedure in 7.2.1 and 7.2.2 using a corresponding number of new specimens and applying a pressure of (200 1) kPa.7.3 Procedure B (Incremental loading of individual specimens)7.3.1 Carry out the procedure in 7.2.1 but without removing the specimen.7.3.2 Increase the pressure to (20 0,1) kPa on the same specimen and note the gauge reading after 30 s, unless a longer time is specified, without removing the specimen.7.3.3 Repeat the procedure in 7.3.2 applying a pressure of (200 1) kPa.
