ASTM D3963/D3963M-00a
(Specification)Standard Specification for Fabrication and Jobsite Handling of Epoxy-Coated Steel Reinforcing Bars
Standard Specification for Fabrication and Jobsite Handling of Epoxy-Coated Steel Reinforcing Bars
SCOPE
1.1 This specification covers the fabrication and jobsite requirements for deformed and plain steel reinforcing bars with protective epoxy coating applied in accordance with Specification A775.
1.2 This specification is applicable for orders in either inch-pound units (as Specification D3963) or SI units (as Specification D3963M).
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
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.
