(see published values for panel type and thickness)

Air Leakage

Measures air leakage through the panel joints

ASTM E 283
Chamber Method

The leakage rate for panel will not exceed 0.01 CFM/SF at 40 psf pressure differential

Water Penetration

Measures water leakage through the panel joints

ASTM E 331
Chamber Method

No water penetration at pressure differential of 50 psf

Strength

Determines the load/span properties of the roof and wall panels

ASTM E 72
Chamber Method

Panel load/span and deflection tables are available

Ignition Properties

Determines ignition temperatures of the panel core material

ASTM D 1929

Self-ignition temperature is 860 degrees F.
Flash-ignition temperature is 842 degrees F.

Surface Burning

Determines the surface burning characteristics of the core and panels
