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 surface of

The part tested shall be identified in t

46、he 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 instead of one.When testing s

47、tructured 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 as stated in Clause 3.If agre

48、ed 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 be used for each test.7.2 Procedure A (New specimens for each pressure)7.2.1 Place a specimen between the clean surfaces of the reference plate and the presser-foot specified in Clause 5.
