Guidelines for the selection of the appropriate standard in a specific application
在特定应用选择合适的标准指南
This group of European standards was developed to specify the characteristics relevant to the use of geotextiles and geotextile-related products in particular applications or works. Sometimes, however, an application can be considered as a part of another application. In such cases, it is not clear which standard to use.
这一组欧洲标准被开发出来，以指定土工织物及其相关产品在特定的应用或工作中相关的特征。然而，有时，一种应用可以看作是另一个应用的一部分。在这种情况下，还不清楚使用哪种标准。
Table C.1 shows how to select the appropriate standard depending on the application. The following steps should be used in this selection process.
表格C.1展示了如何根据应用选择合适的标准。如下步骤在选择过程中应当被采取
a) Select the application from column 1 (vertical) of the table;
选择表格的第一列应用
b) check if the relevant application is mentioned in row 1 (horizontal) in columns 3 to 6:
检查是否相关的应用在第一行的3-6列被提及
1) if not, use the standard quoted in column 2;
如果没有，采用引证的第二列标准
2) if yes, use the standard quoted at the intersection of the first applicable row and first applicable column
如果有，采用引证的第一个应用行和第一个应用列的交叉点对应的标准
