Full Name
ICC-ES AC540 – Acceptance Criteria for Proprietary Welded Threaded Studs
Scope
ICC-ES AC540 establishes the requirements for evaluating proprietary welded threaded studs used in construction. These studs are typically used for attaching various components to steel structures, such as cladding, insulation, and electrical conduits.
The scope of AC540 encompasses several key aspects:
- Material properties: the criteria assess the mechanical properties of the stud and base material, including tensile strength, yield strength, and weldability.
- Welding process: the evaluation includes the examination of the welding process and procedures to ensure the quality and consistency of the welded connection between the stud and the base material.
- Performance testing: the criteria define performance tests to evaluate the stud’s ability to resist various loads, including tension, shear, and fatigue.
- Corrosion resistance: the evaluation also considers the corrosion resistance of the stud and base material, especially for applications in harsh environments.
- Installation: the criteria provide guidelines for the proper installation of the welded threaded studs to ensure their long-term performance and safety.
The primary goal of AC540 is to ensure that proprietary welded threaded studs meet minimum performance standards for structural integrity, durability, and safety, as outlined in relevant building codes and standards. By meeting these criteria, manufacturers can obtain an evaluation report from ICC-ES, which can be used to demonstrate code compliance and gain approval for use in construction projects.
