Tips & Best Practices
-
Always ensure consistent material and testing conditions when comparing values
-
Consider temperature differences as permeability depends on measurement temperature
-
Normalize by specimen thickness for meaningful comparisons using permeability inches
-
Use this conversion to aid engineering design and regulatory compliance evaluations
Limitations
-
Conversion depends on the assumption of consistent testing protocols and material conditions
-
Permeability changes with temperature, so results may vary if conditions differ
-
Thickness effects must be accounted for since permeability inches normalize by specimen thickness
