Standard Specification for Roof and Rock Bolts and Accessories
N F432
Annotation
This specification covers the chemical, mechanical, and dimensional requirements for roof and rock bolts and accessories. Addressed in this specification are double-end threaded and slotted steel bars; fully grouted bolts and threaded bars; mechanical anchorage devices used for point anchorage applications; roof truss systems; partially grouted deformed bolts; formable anchorage devices; cable bolt systems; expandable rock bolts and other frictional anchorage devices. All of these products represent various designs used for ground support systems. This specification can be revised to address new technologies.
The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
This hazard statement applies only to Section 10, Test Methods of this specification. This standard does not purport to address 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.
*A Summary of Changes section appears at the end of this standard
