1.1These test methods cover the tensile testing of para-aramid flat yarns.

1.1.1This standard includes procedures used to measure force at specified elongation (FASE) of para-aramid flat yarns.

1.1.2This standard includes procedures used to measure linear density of para-aramid flat yarns.

1.1.3This standard includes procedures to determine modulus of para-aramid flat yarns.

1.2The 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.

1.3This 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 limitations prior to use.
