Standard Test Method for Determining Tensile Breaking Strength of Glass Fiber Reinforcing Mesh for Use in Exterior Insulation and Finish Systems (EIFS) and EIFS with Drainage Systems, after Exposure to a Sodium Hydroxide Solution

Importancia y uso:

5.1 Glass fiber reinforcing meshes are used to strengthen EIFS and EIFS with drainage. The reinforcing meshes are embedded into base coats that contain portland cement, which potentially exposes the glass fibers in the reinforcing meshes to weakening by the action of alkali. The breaking force following alkali exposure as determined by this method is a factor used to comparatively evaluate the alkali resistance of glass fiber reinforcing meshes in the laboratory.

5.2 This test method does not purport to simulate the conditions that may be encountered in service. The performance of an EIFS or EIFS with drainage is a function of many factors, such as proper installation, rigidity of supporting construction, and resistance of the system to deterioration by other causes.
