ASTM F476-84(2002)

Crime statistics show that the majority of all burglary attacks are on residential property. These test methods are, therefore, designed to aid in identifying a level of physical restraint, by swinging door assemblies, that will help reduce this large increment of crime.

These test methods are not intended to provide a measure of resistance for a door assembly subjected to attacks by skilled burglars on high pay-off targets. These attacks and targets require higher level, more sophisticated resistance, which usually includes alarms, communication, and apprehension systems.

The wall assembly described in 7.3 is considered suitable for the scope of these test methods. Wall construction that differs in dynamic response from that described in 6.3 may require testing in accordance with Section 11.

The primary purpose of this standard is to provide detailed test methods. Acceptance criteria for performance levels are considered a matter for authorities having jurisdiction. Some potential guidelines may be found in Annex A1.

1.1 These test methods cover door assemblies of various materials and types of construction for use in wall openings to deter unwanted intruders.

1.2 Door assemblies, covered by these test methods, also include individual components such as the hinge, lock, door, jamb/strike, and jamb/wall.

1.3 These test methods are designed to measure the capability of a swinging door assembly to restrain or delay and to frustrate the commission of "break-in" crimes.

1.4 These test methods apply primarily to typical entry door assemblies in single- and multi-family residential housing.

1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. 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.
