Standard Test Method for Permanent Deformation of Elastomeric Yarns
|Publication Date:||1 January 2007|
|ICS Code (Yarns):||59.080.20|
This test method covers the determination of the permanent deformation of bare, continuous elastomeric monofilaments and filament yarns made from rubber, spandex, anidex, or other elastomers subjected to prolonged periods of tension. This test method is applicable to elastomeric yarns having a linear density in the range from 4 to 320 tex (36 to 2900 den.).
This test method is not applicable to covered, wrapped, core-spun yarns, or yarns spun from elastomeric staple.
This test method was developed using yarns in the "as-received" condition, but may be used for treated yarns provided the treatment is specified.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
