2、f revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide provides guidelines for the identification and packaging of rolled geosynthetics by
3、 the manufacturer and for thehandling and storage of geosynthetics by the end user. This guide is not to be considered as all encompassing since each projectinvolving geosynthetics presents its own challenges and special conditions. Geosynthetic samples are often taken at manufacturer,supplier, or a
4、t the job site primarily for the purpose of conformance testing and verification. These samples should be properlylabeled for identification purposes.1.2 This guide is intended to aid manufacturers, suppliers, purchasers, and users of geosynthetics for identification, handling,and storage.1.3 This g
5、uide is not applicable for factory fabricated panels due to a different set of identifications for the panel by thefabricator. For Fabricated Geomembrane Panels, refer to Guide D7865.1.4 This guide is not intended for Geosynthetic Clay Liners. For GCLs, refer to Guide D5888.1.5 This guide is also ap

19、f the manufacturer are fully met.4. Significance and Use4.1 For a geosynthetic to be properly used it must be adequately identified and packaged. It must be handled and stored in sucha way that its physical property values are not degraded. Failure to follow good practice may result in the unnecessa
