Full title and description

ASTM E1424-22 — Standard Test Method for Determining the Rate of Air Leakage Through Exterior Windows, Skylights, Curtain Walls, and Doors Under Specified Pressure and Temperature Differences Across the Specimen. This test method establishes a laboratory procedure to measure air leakage through fenestration assemblies under controlled differential temperature and pressure conditions representative of building-envelope service conditions.

Abstract

ASTM E1424-22 provides a repeatable laboratory method for quantifying air leakage of exterior windows, skylights, curtain walls, and doors when subjected to specified pressure and temperature differences across the specimen. The procedure accounts for the effects of thermal expansion/contraction and weather-seal behavior at non-ambient temperatures and converts measured flow rates to standard conditions for comparison. It is intended to measure assembly leakage (not installation leakage) unless specifically adapted for installed conditions.

Scope

This test method gives a laboratory procedure for determining air leakage rates of exterior windows, curtain walls, skylights, and doors under specified differential air temperature and pressure conditions across the specimen. The specified temperature/pressure conditions represent those that may be encountered at the exterior thermal envelope (excluding solar-heat buildup). The method is focused on assembly leakage (not installation) but can be adapted for installed products; it complements ambient-condition tests (see E283) and field tests (see E783).

Key topics and requirements

• Test specimen types: exterior windows, skylights, curtain walls, and doors.
• Controlled differential temperature and pressure conditions across the specimen to simulate thermal and pressure-driven leakage mechanisms.
• Measurement of volumetric air flow and conversion to standard (reference) conditions for comparison.
• Attention to effects of material thermal expansion/contraction, weather-seal compression/shrinkage, and temperature-driven leakage changes.
• Instrumentation, calibration, and reporting requirements to ensure repeatability and comparability with related ASTM fenestration tests.

Typical use and users

Used by product manufacturers, independent testing laboratories, architectural and façade engineers, building-envelope consultants, and code officials to evaluate and compare the air-tightness performance of fenestration assemblies under non-ambient (differential temperature) conditions. Also used in research and product development to assess weather-seal effectiveness and design robustness across temperature ranges.

Related standards

Commonly referenced alongside ASTM E283 (ambient-pressure air leakage laboratory test), ASTM E783 (field air leakage test for installed windows and doors), ASTM E1423 (thermal transmittance of fenestration systems), and other ASTM E06 fenestration practices and test methods. These related standards help provide a complete evaluation of thermal, air, and water performance of fenestration systems.

A: ASTM E1424-22 is a laboratory test method for measuring the rate of air leakage through exterior windows, skylights, curtain walls, and doors under specified pressure and temperature differences across the specimen.

Q: What does it cover?

A: It covers procedures for setting differential temperatures and pressures, measuring volumetric air flow through fenestration assemblies, converting flows to standard conditions, and reporting results — with emphasis on assembly leakage behavior under non-ambient thermal conditions.

Q: Who typically uses it?

A: Manufacturers, independent test labs, façade and building-envelope engineers, architects, and regulatory or code reviewers who need to quantify or compare air-tightness performance of fenestration systems.

Q: Is it current or superseded?

A: As published on October 1, 2022, E1424-22 is the current active revision of the test method (it updates and replaces earlier editions). Users should verify any subsequent revisions or amendments with ASTM before citing in formal specifications.
