This test method is applicable to the design of entire fenestration or impact protection systems assemblies and their installation. As demonstrated by windstorm damage investigations, windborne debris is present in hurricanes and has caused a significant amount of damage to building envelopes A missile propulsion device, r1886 air pressure system, and a test chamber are used to model some conditions which may be representative of windborne debris and pressures in a windstorm environment.

Superimposed on the averaged winds are gusts whose aggregation, for short periods of time ranging from fractions of seconds to a few seconds may move at considerably higher speeds than the averaged winds. This can increase the net outward acting pressure by a factor as high as two. Windstorm damage investigations have shown that the asrm of windborne debris, followed by the effects of repeated or cyclic wind loading, were a major factor in building damage However, if doors and windows and their supports are designed to resist specified loads and the glass is protected by a screen or barrier, they need not be considered openings.

For example, if window glass is likely to be broken by missiles during a windstorm, this is considered to be an opening. Certain values contained in reference documents cited herein may be stated in inch-pound units and must be converted by the user.

ASTM E – Farabaugh Engineering and Testing

It is appropriate to test the strength of the assembly for a time duration representative of sustained winds and gusts in a windstorm. The actual in-service performance of fenestration assemblies and impact protective systems in areas prone to severe windstorms is dependent on many factors. Other test methods, such as Test Methods E and E, do not model gust loadings. The missiles and their associated velocity ranges used in this test method are selected to reasonably represent typical debris produced sstm windstorms.

This test method is applicable to the design of entire fenestration or impact protection systems assemblies and their installation. The performance determined by this test method relates to the ability of elements of the building envelope to remain unbreached during a windstorm.

A potentially more serious result is internal pressurization. A missile propulsion device, an air pressure system, and a test chamber are used to model some conditions which may be representative of windborne debris and pressures in a windstorm environment.

Specific hazard statements are given in Section 7.

Historical Version s – view previous versions of standard. Wind pressures related to building design, wind intensity versus duration, frequency of occurrence, and other factors are considered. The performance determined by this test method relates to the ability of elements ast the building envelope to remain unbreached during a windstorm.

Note 1 — Exception: Link to Active This link will always route to the current Active version of the standard. When the windward wall of a building is breached, the internal pressure in the building increases, satm in increased outward acting pressure on the other walls and the roof.

Thus, there are two options in designing buildings for windstorms with windborne debris: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This standard does not purport to address all of the safety concerns, if any, associated with its use.

Gust wind loads are of relatively short duration. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Link to Active This link will always route to the current Active version of the standard. They are not to be specified for the purpose of testing the adequacy of the assembly to remain 1e886 in a windstorm environment following impact by windborne debris. The resistance of fenestration or impact protective systems assemblies to wind loading after impact depends upon product design, installation, load magnitude, duration, and repetition.
