Focus On: ASTM E330 Structural Testing

June 11, 2024   -  

ASTM E330 is a standard test method established by ASTM International for structural performance testing of exterior windows, doors, skylights, and curtain walls. It outlines the procedures for determining specific elements’ structural performance and helps assess the suitability and safety of building components.

This test is vital to the construction industry as it assesses whether building products meet essential performance standards for structural integrity, especially under wind loads and environmental pressures.

Understanding ASTM E330 Standards

The main purpose of the ASTM E330 test is to assess the structural integrity and performance of building elements under simulated wind loads. The test is intended to represent the effects of a wind load on exterior building surface elements. The standard encompasses a range of building components commonly used in construction projects, including:

  • Windows
  • Doors
  • Skylights
  • Curtain walls

(Applicable curtain wall assemblies may include, but are not limited to, metal, glass, masonry, and stone components).

Testing to the ASTM E330 standard ensures compliance with local regulations and industry benchmarks, affirming safety and reliability in materials and designs.

Key Components and Parameters Evaluated

The ASTM E330 evaluates several key components, including:

  • Deflection: The extent to which the building element deflects under various loads.

  • Load Resistance: The ability of the element to resist the applied loads without failing. 

  • Permanent Deformation: The displacement or change in dimension of the building element after an applied load. 

  • Structural Integrity: The overall structural stability and integrity of the building element during and after the testing process.


How We Conduct ASTM E330 Structural Tests

For best results, ASTM E330 structural testing should occur at an accredited facility with the necessary capabilities to ensure tests are conducted in compliance with all required regulations.

At NGC Testing Services, ASTM E330 testing procedures are followed in strict accordance with those in the test method including test specimen preparation and mounting, testing per Procedure A (load-deflection curve not required) or Procedure B (load-deflection curve required), and reporting of test results.

The major components of the ASTM E330 testing apparatus typically include a test chamber with static pressure tap, an air system with a controllable blower, a pressure-measuring device, and a deflection-measuring system.

For utmost accuracy, we ensure all equipment utilized is capable of performing the test procedure within the allowable tolerances of the test standard. 

Benefits of ASTM E330 Compliance

Investing in ASTM E330 compliance not only assesses structural failure risks but also boosts the reputation and credibility of your building products and elements.
