ASTM E283 / E331 / E547 (glass & fenestration test standards) — Quick report
Overview
- ASTM E283: Standard test method for determining the rate of air leakage through exterior windows, curtain walls, and doors under specified pressure differences across the specimen.
- Scope & purpose: Measures air infiltration/exfiltration (leakage) at set pressure differentials to evaluate weather performance and compliance with design/energy requirements.
- Specimens covered: Windows, skylights, doors, curtain walls, and similar fenestration assemblies.
- Test principle: Apply calibrated air pressures across a specimen in a test chamber and measure airflow; report leakage as cubic feet per minute per linear foot (cfm/ft) or cfm/ft² at specified pressures.
Extensometers are classified based on the magnitude of their errors. Each class has specific limits for "Error of Strain" (relative error) and "Fixed Error" (absolute error). ASTM International Maximum Error of Strain Indicated Typical Application High-precision research Metals testing (Yield strength) Standard metals testing High-elongation polymers Lower accuracy requirements Basic deformation monitoring
(Annex A1), emphasizing the importance of consistent setup for non-contacting devices. astm e83 pdf
The standard categorizes extensometers into "Classes" based on their maximum error and repeatability. When you review an ASTM E83 PDF, you will see a table detailing these requirements: Relative Error of Gauge Length Fixed Error (whichever is greater) Class A ±0.00001 in. Class B-1 ±0.0001 in. Class B-2 ±0.0001 in. Class C ±0.001 in. ASTM E283 / E331 / E547 (glass &
