Abstract: Anchor prequalification in the United States for fastening to concrete is undergoing significant change in order to meet new requirements of ACI 318 Concrete Building Code. In the past and up to the present, there have been limited requirements under the ICBO Uniform Building Code that apply only to the western portion of the United States that use this code. Manufacturers have generally published data based on ASTM E 488 testing requirements or the ICBO ES Acceptance Criteria AC01 or AC58. Testing has been limited to uncracked concrete. These requirements are briefly reviewed.

ACI 318 has approved a code addition based on the Concrete Capacity Design Method to be included in the year 2002 version that requires mechanical anchor prequalification.
ACI Committee 355 Anchorage to Concrete has developed and approved a prequalification standard, ACI 355.2, that meets the new code requirements and is closely harmonized with the European Technical Approval Guideline 001. These prequalification requirements are discussed. The future prequalification requirements of bonded anchors are also included.
