Nonwovens – Part 3. Determination of

Tensile Strength and Elongation (Strip Method)

1 Scope

This Part of GB/T 24218 specifies the test methods of adopting strip method to

measure the tensile properties of the nonwovens.

NOTE. When determining certain filature or laid nonwovens and glass fiber nonwovens, it may

appear abnormity; in this case, the determination procedures can be modified.

6529-2008, ISO 139.2005, MOD)

3 Principle

For the specimen with specified dimension, exert a force that generates constant rate

of elongation along the length direction, and measure its breaking force and elongation

at break.
