ASTM A1132/A1132M : 26 New ASTM DRM Policy

1.1 This specification covers minimum requirements for twisted steel fiber (TSF) for concrete. TSF is a deformed steel wire with a non-circular cross-section that is twisted at least 360° about its axis. It is sufficiently small to be batched in large quantities and randomly dispersed in concrete like other steel fibers.

1.2 In the case of a conflict between a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they in any way violate the requirements of this specification; for example, by waiving of a test requirement or making a test requirement less stringent.

1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
