PASS
Water Resistence
(control and weathered specimens)
AATCC 127
(55cm hydrostatic head of
water for 5 hrs)
No leakage noted
on underside of
control or weathered
samples. PASS
Water Vapor Transmission ASTM E96*
(Method B)
308.9 g/m² 24hrs
2860 ng/Pa/s/m²
50 Perms PASS
Flamespread Index ASTM E-84 Class A PASS
Smoke Development Index ASTM E-84 Class A PASS


*ASTM E 96 - Method B (wet cup method) typically gives a more realistic result for permeance for highly permeable products than does the Method A (dry cup/desiccant method).
