ASTM E283

Air infiltration testing evaluates a window or door system’s ability to limit the passage of air through the assembly under pressure differences caused by wind.

To replicate real-world conditions, the window or door is subjected to a series of controlled pressure differentials that simulate increasing wind speeds. The amount of air passing through the window or door assembly is measured at each pressure level to determine the rate of air leakage.

All products are evaluated in accordance with ASTM E283, the standard test method for determining the rate of air leakage through exterior windows and doors. This testing helps ensure that window and door systems contribute to improved energy efficiency, interior comfort, and overall building performance by minimizing unwanted air infiltration.

ASTM E547

To evaluate resistance to water penetration, Deceuninck tests its window and door systems in accordance with ASTM E547.

During testing, the window or door system is subjected to water at a rate of five gallons per square foot per hour, which is approximately equivalent to eight inches of rainfall per hour. During application of this rate of rainfall, incrementally higher test pressures are applied to determine the product’s maximum level of performance under these extreme conditions.

During the test, a member of the testing team located on the inside of the test assembly carefully monitors for any water leakage past the innermost plane of the window or door.

ASTM E330

Structural testing evaluates a window or door system’s ability to withstand the high-pressure forces generated by strong wind loads.

To simulate real-world conditions, the product is tested under both positive and negative pressure.

This evaluation is performed to ASTM E330 standard test method for structural performance of exterior windows, doors, skylights and curtainwalls.

ASTM E1886, E1996, and Miami Dade TAS 201 202 203

Impact testing evaluates a window or door system’s ability to help protect the building envelope from windborne debris during high-velocity wind events, such as hurricanes. This test is performed to various test methods such as ASTM E1886 and E1996 and Miami Dade TAS 201 202 203.

To test impact resistance, a nine-pound wooden two by four is fired from an air cannon at a speed of fifty feet per second at targeted locations on a window.

To pass the test, the two by four must not penetrate the specimen.

Other In-House Tests

To ensure durability and safety, Deceuninck also performs these critical product tests:

  • Weld Strength
  • Deglazing
  • Hardware Load
  • Forced Entry Resistance
  • Operation Force
Deceuninck product testing

In Arizona, where extreme heat and prolonged sun exposure create challenging conditions, Deceuninck operates an outdoor testing hut to evaluate the long-term effects of ultraviolet radiation, heat, and thermal cycling measured over extended periods of time.

This real-world testing, combined with Deceuninck’s extensive in-house laboratory testing, further validates long-term product performance and supports confidence in the durability and reliability of window and door systems.
