WebThe SI unit for permeance is the kilogram per second per square meter per pascal. 1 kg·s⁻¹·m⁻²·Pa⁻¹ ≈ 1.74784x10+10 US perms ≈ 1.15191x10+10 metric perms. Using the Permeation, Permeance, Water Vapor Permeability Converter Converter WebJan 20, 2024 · For these materials, which also tend to have a much higher permeance rating than under-slab vapor barriers, E96 is a “better” choice. Similarity #2 - Both Test Methods are Accepted by ASTM E1745. Despite their differences, E96 and F1249 are both useful test methods.
