Designation:D6207–03
Standard Test Method for
Dimensional Stability of Fabrics to Changes in Humidity and
1
Temperature
This standard is issued under the fixed designation D 6207; 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 (e) indicates an editorial change since the last revision or reapproval.

standing screens, office partitions, and furniture systems.
5. Significance and Use
1.2 The values stated in SI units are to be regarded as the
standard. The values in parentheses are approximate inch- 5.1 The measured dimensional stability of a fabric deter-
mines whether a fabric has the potential to retain its original
pound unit equivalents and are for information only.
1.3 This standard does not purport to address all of the shape and remain stable, indicating it will not bubble or sag
over time, when applied over a substrate, and its suitability for
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appro- a specified use.
5.2 This test method is recommended for acceptance testing

bility of regulatory limitations prior to use. of commercial shipments however, caution is advised since
information about between laboratory precision is incomplete.
