Purpose

Procedure

Results

Thermal Resistance

Determines insulating properties of the panels

ASTM C 236 Guarded Hot Box

Good R values for an HCFC Foam System
(see published values for panel type and thickness)

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

Wind Uplift

Determines uplift resistance of roof panels in high winds

Factory Mutual STD. 4471(1995)

RWP Roof Panels have a class 1-60 rating with a 5' 0" purlin spacing

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
