Full Name
ICC-ES AC533 – Acceptance Criteria for Drainable Threshold Used with Exterior Doors
Scope
ICC-ES AC533 outlines the acceptance criteria for evaluating drainable thresholds used with exterior doors. These thresholds are designed to prevent water intrusion into buildings by providing a drainage path for water that may accumulate at the door sill.
The scope of AC533 includes:
- Performance requirements: the criteria define the performance requirements for drainable thresholds, including their ability to resist water penetration, wind-driven rain, and air infiltration.
- Testing procedures: it establishes standardized test methods for evaluating the performance of drainable thresholds under various conditions, such as simulated rainfall, wind pressure, and air leakage tests.
- Material compatibility: it addresses the compatibility of drainable thresholds with different door types, frame materials, and weatherstripping systems.
- Installation requirements: it provides guidelines for the proper installation of drainable thresholds to ensure their effectiveness in preventing water intrusion.
The primary goal of AC533 is to ensure that drainable thresholds meet minimum performance standards for water resistance and durability, 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.
