ICC-ES AC525
Full Name
ICC-ES AC525 – Acceptance Criteria for Grade 90 [600] Intermediate High-Strength Steel Reinforcing Bars
Scope
ICC-ES AC525 outlines the acceptance criteria for evaluating Grade 90 [600] intermediate high-strength steel reinforcing bars. These bars are used in reinforced concrete structures and are designed to provide higher strength and improved performance compared to traditional Grade 60 reinforcing bars.
The scope of AC525 covers various aspects of these reinforcing bars, including:
- Mechanical properties: evaluation of the tensile strength, yield strength, elongation, and bendability of the bars to ensure they meet the specified requirements for Grade 90 [600] steel.
- Chemical composition: assessment of the chemical composition of the steel to verify that it falls within the acceptable limits for the specified grade.
- Production and manufacturing processes: verification of the production and manufacturing processes used to produce the bars, including the rolling, heat treatment, and surface preparation methods.
- Quality control and assurance: evaluation of the manufacturer’s quality control and assurance program to ensure consistent production of high-quality reinforcing bars.
- Marking and identification: verification of the marking and identification procedures used to properly label the bars with their grade, size, and other relevant information.
The evaluation process typically involves a combination of testing, document review, and inspection of the manufacturing facilities to ensure compliance with the acceptance criteria.
