IAPMO UES EC 029
Full Name
IAPMO UES EC 029 – Evaluation Criteria for Standing Seam Metal Roof-Mounted Rail-Type Snow Retention Systems
Scope
IAPMO EC 029 outlines the evaluation criteria for standing seam metal roof-mounted rail-type snow retention systems. This standard, developed by the International Association of Plumbing and Mechanical Officials (IAPMO) Uniform Evaluation Service (UES), focuses on assessing the suitability and performance of snow retention systems installed on standing seam metal roofs.
The scope of EC 029 includes:
- Purpose: to establish the testing requirements, procedures, documentation, and analysis methods for determining allowable loads for roof-mounted snow retention systems for recognition in an evaluation report issued by an approved certification body.
- Applicability: it is intended for evaluating the design of rail-type snow retention systems connected to standing seam metal roof covering panels using seam clamps to resist in-plane, down-slope snow loads. It does not consider uplift, sideways, or prying loads.
- Performance requirements: it defines the minimum performance standards for snow retention systems, including load capacity, structural integrity, and durability, to ensure they can effectively prevent snow and ice from sliding off the roof.
- Testing procedures: it outlines standardized testing methods to evaluate the performance of snow retention systems under various snow load conditions, considering factors such as roof slope, snow density, and wind exposure.
- Documentation requirements: it specifies the documentation that manufacturers need to provide for evaluation, including design calculations, material specifications, and installation instructions.
By adhering to IAPMO EC 029, manufacturers can ensure that their snow retention systems meet the necessary standards for safety and performance. This can lead to their products being listed and labeled by IAPMO UES, which helps build trust and acceptance in the market. Builders and roofing contractors can also refer to EC 029 to select appropriate snow retention systems for their projects, ensuring compliance with building codes and safety regulations.
