temperatue conditions required by ASTM material specifications shall take precedence over those recommended in this practice.
Standard conditions are presented where both surfaces are exposed to fixed ambient temperatures that are typical for testing building constructions, both insulated and uninsulated (Table 2).
Standard conditions are presented where the temperatures of the two surfaces are fixed and surface coefficients are not considered (Table 3).
For conditions where the temperature of
