ASTM D6707/D6707M-06(2016)e1

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Specification for
Circular-Knit Geotextile for Use in Subsurface Drainage
Applications
This standard is issued under the fixed designation D6707;D6707/D6707M; the number immediately following the designation indicates
the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
ε NOTE—Designation was changed to dual and units information was corrected editorially in January 2016.
1. Scope
1.1 This specification covers circular-knit geotextiles for use on the outside of perforated pipes and Class B geocomposites per
Specification D7001 in drainage applications.
1.2 The tests used to characterize the geotextile are intended to ensure good workmanship and quality, and are not necessarily
adequate for design purposes in view of the importance of environmental factors and specific performance objectives. Tests have
been selected with essentially neutral aqueous systems in mind. Other tests may be necessary to establish chemical resistance and
durability under the conditions of a particular application.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in non-conformance with the standard.
1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all
of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability of regulatory requirements prior to use.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 circular knit—a structure produced by interlooping one or more ends of yarn or comparable material in a continuously
circular orientation around the fabric.
3.1.2 filtration—the equilibrium soil to geotextile system that allows for adequate liquid flow with limited soil loss across the
plane of the geotextile over the service lifetime compatible with the application under consideration.
3.2 Definitions in this standardspecification are in accordance with TerminologyTerminologies D123 and D4439, unless
otherwise specified.
4. Classification
4.1 The circular-knit geotextiles covered by this specification are classified as follows:
4.1.1 Type A: fabric
This specification is under the jurisdiction of ASTM Committee D35 on Geosynthetics and is the direct responsibility of Subcommittee D35.03 on Permeability and
Filtration.
