AAMA 1503-09 Voluntary Test Method for Thermal Transmittance and Condensation Resistance of Windows, Doors and Glazed Wall Sections

This standard defines a voluntary test method for measuring thermal transmittance and condensation resistance of fenestration products.

AAMA 1503-09 is a voluntary test method for measuring the thermal characteristics of windows, doors, and glazed exterior wall sections under steady-state conditions. It covers thermal transmittance, air infiltration rate, and condensation resistance factor evaluation using calibrated hot box methods and standardized test conditions.

Application Scope: Intended for vertically oriented windows, doors, and representative glazed wall sections used for comparative thermal performance testing.
