ASTM D8505/D8505M-23

1.1This specification covers basalt and glass fiber reinforced polymer (BFRP and GFRP, respectively) bars, provided in straight (longitudinal) cut lengths, of solid round cross-section, and having a surface enhancement for internal concrete reinforcement applications. Bars covered by this specification shall meet the requirements for geometric, material, mechanical, and physical properties as described herein.

1.2Subsection 1.6 defines the type of FRP bars that are out of the scope of this specification.

1.3Bars produced according to this standard are qualified using the test methods and must meet the requirements given in Table 1. Quality control and certification of production lots of bars are completed using the test methods and must meet the requirements given in Table 2.

1.4The standard sizes and dimensions of FRP bars and their number designations are given in Table 3.

1.5The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables) shall not be considered as requirements of the specification.

1.6The following FRP bar materials are not covered by this specification:

1.7This specification is applicable for either SI (as Specification D8505M) or US units (as Specification D8505).

1.8The values stated in either SI units or US units are to be regarded as standard. Within the text, the US units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.9This 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.

1.10This 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.
