IAPMO UES EC 047
Full Name
IAPMO UES EC 047 – Evaluation Criteria for Membrane Mitigation Barrier Systems Used for Methane Gas Mitigation
Scope
IAPMO EC 047 outlines the evaluation criteria for membrane mitigation barrier systems used for methane gas mitigation. This standard is developed by the International Association of Plumbing and Mechanical Officials (IAPMO) Uniform Evaluation Service (UES).
The scope of EC 047 includes:
- Purpose: to establish requirements for membrane mitigation systems used as barriers against the permeation and migration of methane gas in accordance with Chapter 18 of the International Residential Code (IRC).
- Applicability: it applies to membrane mitigation systems intended for use as vapor retarders/barriers under concrete slabs and as part of passive methane mitigation systems as per the IRC and other applicable codes.
- Requirements: the standard covers requirements for materials, design, testing, and performance of membrane mitigation systems. This includes evaluating their methane permeability, tensile strength, puncture resistance, seam strength, and compatibility with other construction materials.
- Installation: it also provides guidance on the proper installation of these systems to ensure their effectiveness in mitigating methane gas migration.
By adhering to IAPMO EC 047, manufacturers can ensure that their membrane mitigation systems meet the necessary standards for safety and performance. Builders and contractors can also refer to EC 047 to select suitable systems for their projects.
