A proposed new standard from ASTM Intl. Committee D13 on Textiles will be useful to those involved in the design and evaluation of garments that are meant to fit tightly on the body. The proposed new standard, ASTM WK27572, Test Method for Elastic/Stretch Properties of Textile Materials, is being developed by Subcommittee D13.59 on Fabric Test Methods, General.

“Elongation using a specified load only tells us a part of what we’d like to know,” says Kham Viengkham, materials test engineer, Nike Inc., and a member of D13. “We want to be able to identify the yield point where the material begins to experience permanent deformation or is no longer elastic. This point is useful to designers, product developers and pattern makers for properly sizing garments by utilizing an amount of stretch below a materials yield point. This area can be called the elastic region, where we can better predict the behavior of a material.”

The subcommittee welcomes participation in the ongoing development of ASTM WK27572, particularly from designers who would be using the standard. ASTM Intl. welcomes and encourages participation in the development of its standards. For more information on becoming an ASTM member, click here.
