ICC-ES AC58 and ICC-ES AC308

Hi Customer,

thank you for reaching out to us. ICC-ES AC58 is an acceptance criteria published in 1995 used for evaluating adhesive anchor systems in concrete and masonry base materials. In 2005, ICC-ES AC308 was published for adhesive anchors in concrete, and ICC-ES AC58 was changed to only address masonry base materials.

In general, AC308 improved the testing and assessment of adhesive anchor systems in concrete based on research on the behavior of these systems. AC58 is still the state-of-the-art with respect to adhesive anchor systems in masonry. Hilti has maintained their focus on evaluating adhesive anchor systems to the highest standards. As such, Hilti maintains ICC-ES evaluation reports for adhesive anchors in concrete according to AC308 and in masonry according to AC58. I hope I have answered your question. If there is anything else, please let me know.

Best Regards
Justin
