1、Designation: F3085 14 (Reapproved 2018) An American National StandardStandard Specification forAir Soft Gun Barrel Blocking Devices1This standard is issued under the fixed designation F3085; the number immediately following the designation indicates the year oforiginal adoption or, in the case of re
2、vision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis standard is intended to outline basic performance requirements for barrel blocking devices. A
3、barrel blocking device is a critical piece of safety equipment used in the sport of air soft.Air Soft tactical games are an activity that, like all sports, has intrinsic hazards. These hazardsinclude being hit by air soft projectiles. Protective equipment cannot eliminate all injuries but willsubsta
4、ntially reduce their severity and frequency. A barrel blocking device is an additional safetydevice that, when meeting this standard and properly used, can substantially reduce the severity andfrequency of injuries. Air Soft gun barrels are not all the same inside diameter, thus necessitatingperform
5、ance specifications for barrel blocking devices that match the barrel blocking device to a barreldiameter. This specification is written within the current state-of-the-art of air soft gun barrel and airsoft barrel blocking device technology. The intent is to revise this specification whenever subst
6、antiveinformation becomes available which justifies revising existing requirements or adding newrequirements.1. Scope1.1 This specification covers air soft gun barrel blockingdevices that may be inserted or otherwise function to preventan airsoft projectile from leaving the muzzle or the confines of
7、the barrel blocking device.1.2 The values stated in SI units are to be regarded as thestandard. The inch-pound units given in parentheses areprovided for information only.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility
8、 of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization esta

Significance and Use4.1 This specification establishes performa
20、nce requirementsand test methods to provide a reasonable degree of safety in thenormal use of barrel blocking devices in air soft guns.5. Conformance5.1 Barrel blocking devices shall not, either by label or othermeans, indicate conformance with this specification unlessthey conform to all applicable
21、 requirements contained herein.6. General Requirements6.1 PerformanceUpon any discharge of an air soft pro-jectile from an air soft gun with an appropriate barrel blockingdevice properly installed according to the manufacturersinstructions, the barrel blocking device must remain inserted orover the
22、muzzle and prevent an air soft projectile from exitingthe muzzle or the confines of the muzzle blocking device. Testsshall be conducted in accordance with 7.2.6.2 All barrel blocking devices shall completely cover orblock the exit orifice of the barrel. Some barrel blockingdevices make use of a vent
23、 port that allows the release ofexcess pressure in the barrel of the air soft gun. The totalcalculated area of all ports of this type in any barrel blockingdevice must less than 2.5 mm2.7.
