IAPMO UES EC 014
Full Name
IAPMO UES EC 014 – Evaluation Criteria for High Density Polyethylene (HDP) Lath Used in Cementitious Exterior Wall Coatings or Exterior Cement Plaster (Stucco)
Scope
IAPMO EC 014 outlines the evaluation criteria for high density polyethylene (HDPE) lath used in cementitious exterior wall coatings or exterior cement plaster (stucco). This standard is developed and maintained by the International Association of Plumbing and Mechanical Officials (IAPMO) Uniform Evaluation Service (UES).
The scope of EC 014 includes:
- Performance requirements: it defines the minimum performance criteria for HDPE lath, including tensile strength, impact resistance, and alkali resistance, to ensure its suitability for use in exterior wall coatings and stucco systems.
- Testing procedures: it specifies the standardized testing methods to evaluate the performance of HDPE lath under various conditions, such as tensile loading, impact, and exposure to alkaline environments.
- Material specifications: it outlines the acceptable materials and manufacturing processes for HDPE lath to ensure its quality and durability.
- Installation guidelines: it provides guidance on the proper installation of HDPE lath in cementitious exterior wall coatings and stucco systems to ensure its optimal performance and adherence to building codes.
Manufacturers of HDPE lath can seek evaluation and listing by IAPMO UES based on EC 014 to demonstrate compliance and gain acceptance in the industry. Builders and contractors can also refer to EC 014 to select suitable HDPE lath for their projects.
