This standard does not purport to address all of the safety concerns, if any, associated with its use. The damage caused by windborne debris during windstorms goes beyond failure of building envelope components such as windows, doors, and curtain walls.

Thus, there are two options in designing buildings for windstorms with windborne debris: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Specific hazard statements are given in Section 7.

This test method is applicable to the design of entire fenestration or impact protection systems assemblies and their installation. Specific hazard statements are given asmt Section 7.

Other test methods, such as Test Methods E and E, do not model gust loadings. The actual in-service performance e886 fenestration assemblies and impact protective systems in areas prone to severe windstorms is dependent on many factors.

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.

Note 1 — Exception: It is appropriate to test the strength of the assembly for a time duration representative of sustained winds and gusts in a windstorm. Values given in parentheses are for information only.

Gust wind loads are of relatively short duration. 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. Wind pressures related to building design, wind intensity versus duration, frequency of occurrence, and other factors are considered.

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 environment. 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 This test method is applicable to the design of entire fenestration or impact protection systems assemblies and their installation.

Certain values contained in reference documents cited herein may be stated in inch-pound units and must be converted by the user. The missiles and their associated velocity ranges used in this test method are selected to reasonably represent typical debris produced by windstorms.

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. 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. 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 can increase the net outward acting pressure by a factor as high as two. Active view current version of standard.

For example, if window glass is likely to be broken by missiles during a windstorm, this is considered to be an opening.

The latter approach reduces the likelihood of exposing the building contents to the weather. As demonstrated by windstorm damage investigations, windborne debris is present in hurricanes and has caused a significant amount of damage to building envelopes Certain values contained in reference documents cited herein may be stated in inch-pound units and must be e186 by the user.

Typical debris in hurricanes consists of missiles satm, but not limited to, roof gravel, roof tiles, signage, portions of damaged structures, framing lumber, roofing materials, and sheet metal 4, 7, 9.

Breaching aztm the envelope exposes a building’s contents to the damaging effects of continued wind and rain 1, Design pressures based on wind speeds with a mean recurrence interval usually 25 to years that relates to desired levels zstm structural reliability and are appropriate for the type and importance of the building 1.

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. 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 unbreached 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. The performance determined by this test method relates to the ability of elements of the building envelope to remain unbreached during a windstorm.

When the windward wall of a building is breached, the internal pressure in the building increases, resulting in increased outward acting pressure on the other walls and the roof. 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.
