Windstorm damage investigations have shown that the effects of windborne debris, followed by the effects of repeated or cyclic wind loading, were a major factor in building damage Certain values contained in reference documents cited herein may ast stated in inch-pound units and must be converted by the user.

Historical Version s – view previous versions of standard. Gust wind loads are of relatively short duration. It is the responsibility of the user of this standard to establish appropriate safety e1868 health practices and determine the applicability of regulatory limitations prior to use.

This test method is applicable to the design of entire fenestration or impact protection systems assemblies and satm installation. As demonstrated by windstorm damage investigations, windborne debris is present in hurricanes and has caused a significant amount of damage to building envelopes Values given in parentheses are for information only.

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.

However, if doors and windows and their supports are designed to resist specified loads and the glass is protected by a asrm or barrier, they need not be considered openings.

The missiles and their associated velocity ranges used in this test ast are selected to reasonably represent typical debris produced by windstorms. Typical debris in hurricanes consists of missiles including, but not limited to, roof gravel, roof tiles, signage, portions of damaged structures, framing lumber, roofing materials, and sheet metal 4, 7, 9.

They are not to be specified for the purpose of testing the adequacy of the assembly to remain unbreached in a windstorm environment following impact by windborne debris.

Specific hazard statements are given in Section 7. When the windward wall of a building is breached, the internal pressure in the building increases, resulting e186 increased outward acting pressure d1886 the other walls and the roof.

A potentially more serious result is internal pressurization. The performance determined by this test method relates to the ability of elements of the building envelope to remain unbreached during a windstorm.

The latter approach reduces the likelihood of exposing aztm building contents to the weather.

Certain values contained in reference documents cited herein may be stated in inch-pound units and must be converted by the user. Wind pressures related to building design, wind intensity versus duration, frequency of occurrence, and other factors are considered.

Superimposed on the averaged winds are gusts aastm 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. 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.

The damage caused by windborne debris during windstorms goes beyond failure of building envelope components such as windows, doors, and curtain walls. The actual in-service performance of fenestration assemblies and impact protective systems in areas prone atsm severe windstorms is dependent on many factors.

The resistance of fenestration or impact protective systems assemblies to wind loading after impact depends upon product design, installation, load magnitude, duration, and repetition. Design pressures based on wind speeds with a mean recurrence interval usually 25 to years that relates to desired levels of structural reliability and are appropriate for the type and importance of the building 1.

However, these test methods do not account for other factors such as impact from windborne debris followed by fluctuating pressures associated with a severe windstorm astn. Thus, there are two options in designing buildings for windstorms with windborne debris: It is appropriate to test the strength of the assembly for a time duration representative of sustained winds and gusts in a windstorm.

Breaching of the envelope exposes a building’s contents to the damaging effects asstm continued wind and rain 1, The performance determined by this test method relates to the ability of elements of the building envelope to remain unbreached during a windstorm.

This can increase the atm outward acting pressure by a factor as high as two.

For example, if window glass is likely to be broken by missiles during a windstorm, this is considered to be an opening. This standard does not purport to address all of the safety concerns, f1886 any, associated with its use.
