1、Designation: D 4873 02Standard Guide forIdentification, Storage, and Handling of Geosynthetic Rollsand Samples1This standard is issued under the fixed designation D 4873; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide provides guidelines for the identification andpackaging of rolled geosynthetics by the manufacturer and fo
3、rthe handling and storage of geosynthetics by the end user. Thisguide is not to be considered as all encompassing since eachproject involving geosynthetics presents its own challenges andspecial conditions. Geosynthetic samples are often taken atmanufacturer, supplier, or at the job site primarily f
4、or thepurpose of conformance testing and verification. Thesesamples should be properly labeled for identification purposes.1.2 This guide is intended to aid manufacturers, suppliers,purchasers, and users of geosynthetics for identification, han-dling, and storage.1.3 This guide is not applicable for
5、 factory fabricated panelsdue to a different set of identifications for the panel by thefabricator.1.4 This guide is also applicable to geosynthetic samples.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user o
6、f this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

11、 which provide information that can be usedfor making statistical inferences about the population(s) fromwhich the specimens are drawn.4. Significance and Use4.1 For a geosynthetic to be properly used it must beadequately identified and packaged. It must be handled andstored in such a way that its p

Failure to follow good practice may result in theunnecessary failure of the geosynthetic in a properly designedapplication.4.2 This guide is not intended to replace project-specificstorage, handling, identification, packaging, or installationrequirements or q

Roll identification should include, at minimum, thename of the manufacturer or supplier, product or
17、style number,and the unique roll number. Identification should also includethe width and length of the geosynthetic roll. Any other uniquecharacteristics should be clearly identified. For rolls with noidentification on the inside of the core, once the roll isunwrapped or samples taken, labels on the
18、 outer wrap or theroll packaging should be removed and placed inside the roll fortraceability. All designations should be readable for clearidentification.NOTE 1Rolls bundled or strapped as a single unit could be regardedas a single roll for identification purposes provided all the rolls remain asa

If practicable, use fork lift trucks fittedwith poles that can be inserted
20、into the cores of rolls. Be surethat the poles are at least two thirds the length of the rolls toavoid breaking the cores and possibly damaging the geosyn-thetic. Slings may be used to carry relatively rigid rolls ofgeosynthetics, such as geonets or geomembranes, provided thatthe slings do not cause
21、 damage to the rolls. Do not drag therolls as damage may result.5.2.2 Geosynthetics, when possible, should be stored whileelevated off of the ground and covered to ensure adequateprotection from the following:5.2.2.1 Precipitation (becauses geotextile roll goods satura-tion leads to handling difficu
