IAPMO UES EC 011
Full Name
IAPMO UES EC 011 – Evaluation Criteria for Single Skin Steel Roof and Wall Panels
Scope
IAPMO EC 011 defines the evaluation criteria for single skin steel roof and wall panels. It’s a standard developed by the International Association of Plumbing and Mechanical Officials (IAPMO) Uniform Evaluation Service (UES) to assess the suitability of these panels for construction.
The scope of EC 011 includes:
- Performance requirements: it defines the minimum performance standards for structural integrity, weather resistance, fire resistance, and other relevant factors.
- Testing procedures: it outlines standardized testing methods to evaluate the strength, durability, and performance of single skin steel roof and wall panels under various conditions.
- Material specifications: it specifies acceptable materials and construction requirements for these panels to ensure safety and compliance with building codes.
- Design considerations: it provides guidance on design principles and calculations to ensure proper structural and functional performance.
Specifically, EC 011 covers evaluation criteria for:
- Strength: bending strength, concentrated load resistance, pull-out and pull-over resistance, uplift resistance, and shear strength.
- Weather resistance: air and water infiltration resistance, and drag resistance.
- Clip/Fastener attachment: evaluation of clip/fastener attachment schedules.
It’s important to note that EC 011 excludes in-plane shear resistance, composite panel systems, exposed fastener panels, and panel materials other than steel from its scope.
Manufacturers and builders can refer to EC 011 for guidance on designing and constructing safe and reliable single skin steel roof and wall panels. They can also seek evaluation and listing by IAPMO UES based on EC 011 to demonstrate compliance and gain acceptance in the industry.
