ASTM A1061/A1061M-09

1.1 These test methods describe procedures for testing the mechanical as well as relaxation properties of multi-wire steel strand.

1.2 These test methods are intended for use in evaluating specific strand properties prescribed in specifications for multi-wire steel strand, but they do not quantify acceptance criteria specified in the applicable specification for the strand being tested.

1.3 The 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.

1.4 This 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.
