Determines rate of air leakage through exterior windows, curtain walls, and doors under specific pressure differences across a specimen. This test seals a test specimen into or against one face of an air chamber, supplies air to or exhausts air from the chamber at a rate required to maintain the specific test pressure difference across the specimen, and measures the resultant air flow across the specimen.

Provides structural performance of exterior windows, doors, skylights, and curtain walls by uniform static air pressure difference. This test seals the test specimen into or against one face of a test chamber, supplies air to or exhausts air from the chamber according to a specific test pressure loading program, at the rate required to maintain the test pressure difference across the specimen, and observes, measures, and records the deflection, deformations, and nature of any distress of failures of the specimen.

Detects water penetration of exterior windows, skylights, doors, and curtain walls by uniform static air pressure difference. This test seals the test specimen into or against one face of a test chamber, supplies air to or exhausts air from the chamber at the rate required to maintain the test pressure difference across the specimen for a time cycle specified while spraying water onto the outdoor face of the specimen at the required rate, and observes any water penetration.

Detects water penetration of exterior windows, skylights, doors, and curtain walls by cyclic static air pressure difference. This test seals the test specimen into or against one face of a test chamber, supplies air to or exhausts air from the chamber at the rate required to maintain the test pressure difference across the specimen for a time cycle specified while spraying water onto the outdoor face of the specimen at the required rate, and observes any water penetration.

Measures air leakage through installed exterior windows and doors. This test seals a chamber to cover the interior or exterior face of the specimen, supplies air to or exhausts air from the chamber at a rate required to maintain the specified test pressure difference across the specimen, and measures the resultant air flow across the specimen.

Analyzes deglazing force of fenestration products. This test measures operating (or removable) window sashes, storm sashes, and sliding glass door panels against forces tending to deglaze the construction.

Determines water penetration of installed exterior windows, skylights, doors, and curtain walls by uniform or cyclic static air pressure difference. This test seals a chamber to the interior or exterior face of the specimen to be tested, supplies air to a chamber mounted on the exterior or exhausts air from a chamber mounted on the interior at the rate required to maintain the test pressure difference across the specimen while spraying water onto the outdoor face of the specimen at the required rate, and observes any water penetration.

Measures the performance of exterior windows, curtain walls, doors, and impact protective systems impacted by missiles and exposed to cyclic pressure differentials. This test mounts and braces the test specimen to a cyclic test chamber, impacts the test specimen with a missile(s), applies cyclic static pressure differentials across the test specimen in accordance with a specified test loading program, observes and measures the condition of the test specimen, and reports the results.

Analyzes performance of exterior windows, curtain walls, doors and impact protective systems impacted by windborne debris and hurricanes. Large Missile Impact (LMI) testing provides a basis for judgment of the ability of applicable elements of the building envelope to remain un-breached during a hurricane. While this standard was developed for hurricanes, it may be used for other types of similar wind-storms capable of generating windborne debris.

Measures the forced entry resistance of window assemblies, excluding glazing impact. This procedure mounts a specimen into a test assembly fixture, which in turn is mounted to a wall support fixture, and after removing all exterior fasteners and loose component items, specific loads of forces are applied to the window test specimen in a prescribed sequence. This test establishes a measure of resistance for window assemblies subjected to attacks (other than impacting glazing materials) by unskilled or opportunistic burglars.

Measures the forced entry resistance of sliding door assemblies, excluding glazing impact. This procedure mounts a sliding door specimen into a test assembly fixture, which in turn is mounted to a wall support fixture, and after removing all exterior fasteners and loose component items, specified load forces are applied to the sliding door specimen in a prescribed sequence. This test establishes a measure of resistance for window assemblies subjected to attacks (other than impacting glazing materials) by unskilled or opportunistic burglars.

Determines the operating force of sliding windows and door assemblies by using an ISO 17025-certified and calibrated force gauge with a peak hold and continuous reading capability. Pressure is applied evenly to operate an operable sash or panel, then the test specimen is mounted in a rigid support frame. The weight or force is applied and increased until the sash or panel is put into motion, which determines breakaway force.
