ASTM E330 Test Method for Structural Performance of Exterior Windows, Doors, Skylights, and Curtain Walls with Uniform Static Air Pressure Difference

EUROLAB laboratory provides testing and compliance services within the scope of ASTM E330 standard. The ASTM E330 standard describes the determination of the structural performance of exterior windows, doors, skylights and curtain walls under uniform static air pressure differences using a test chamber. This test method is applicable to curtain wall assemblies including but not limited to metal, glass, masonry and stone components.

This test method is intended to evaluate only the structural performance associated with the specified test specimen, not the structural performance of the adjacent structure. Correct use of this test method requires knowledge of the principles of pressure and deflection measurement. This test method describes the device and procedure to be used to apply evenly distributed test loads to a sample.

• Procedure A should be used when no load-deflection curve is required.
• Procedure B should be used when a load-deflection curve is required.

This test method is a standard procedure for determining structural performance under uniform static air pressure difference. This is typically intended to represent the effects of a wind load on exterior building surface members. Actual loading on building surfaces is quite complex, varying with wind direction, time, ground clearance, building shape, terrain, surrounding structures, and other factors. Wind load resistance of many windows, curtain walls and door assemblies is also complex and depends on the overall product.

Design wind speeds are selected for specific geographic locations and probabilities of occurrence based on data from wind speed maps such as those provided in ASCE/SEI 7. These wind speeds are translated into uniform static air pressure differences and times moving inward and outward. The complexities of wind pressures must be considered in relation to building design, wind intensity and duration, frequency of occurrence and other factors. High winds superimposed on sustained winds that can move at speeds much higher than sustained winds for short periods of one second to several seconds. Analytical procedures, wind tunnel studies, computer simulations, and model analysis in ASCE/SEI 7 assist in determining the appropriate design wind loads on the exterior elements of buildings. In general, wind load times from ASCE/SEI 7 are 2 to 10 s and depend on the specific time reference used in determining the pressure coefficients.

This test method consists of supplying or venting air into the chamber according to a specified test-loading schedule at the rate required to seal the test specimen against one face or face of a test chamber, maintaining the test pressure difference across the specimen. and to observe, measure and record the deflection, deformations and structure of any distortion or distortion in the sample.

The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (except in tables and figures) will not be accepted as requirements of the standard. Values ​​stated in SI units or inch-pound units should be considered separately as standard. The values ​​specified in each system are not necessarily exact equivalents; therefore, to ensure compliance with the standard, each system should be used independently of the other and the values ​​obtained from the two systems should not be combined.
