ICC-ES AC284
Full Name
ICC-ES AC284 – Acceptance Criteria for HVAC Duct Supports
Scope
ICC-ES AC284 establishes the acceptance criteria for evaluating the strength of various support systems for HVAC ducts. This includes assessing the structural integrity of the supports and their ability to withstand the loads and stresses imposed by the ductwork.
The scope of AC284 encompasses the following aspects:
- Material specifications: outlining the acceptable materials for duct supports, including their strength, durability, and corrosion resistance.
- Design considerations: providing guidelines for the design of duct supports, considering factors such as duct size, weight, and configuration, as well as the environmental conditions in which they will be used.
- Installation requirements: specifying the proper installation procedures for duct supports to ensure their secure attachment to the building structure and their ability to effectively support the ductwork.
- Testing and evaluation methods: establishing procedures for evaluating the structural performance of duct supports through laboratory testing and analysis, including tests for load capacity, deflection, and fatigue resistance.
By establishing these acceptance criteria, ICC-ES AC284 aims to ensure the safe and reliable support of HVAC duct systems in buildings. It provides a standardized framework for manufacturers, engineers, and building officials to assess the suitability of various duct support systems for different applications.
