1、Designation: F3085 14 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 revision, the year o

2、f 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. Abarrel blocking de

3、vice 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 willsubstantially reduce the

4、ir 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 necessitatingperformance specification

5、s 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 substantiveinformation

6、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 ofthe barrel blockin

Significance and Use4.1 This specification establishes performance requirementsand test methods to provide a reasonable degree of safety in thenormal use of barrel blocking dev

18、ices 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 requirements contained herein.6. General Requirements6.1 PerformanceUpon any discharge of an air soft pro-jectil

19、e 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 muzzle and prevent an air soft projectile from exitingthe muzzle or the confines of the muzzle blocking device. T

20、estsshall 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 port that allows the release ofexcess pressure in the barrel of the air soft gun. The totalcalculated area of al

21、l ports of this type in any barrel blockingdevice must less than 2.5 mm2.7. Test Methods7.1 No precision statement on any of the following testmethods is available at this time.7.2 Barrel Blocking Device Retention Test:7.2.1 SignificanceThis method is performed to ensure thatthe barrel blocking devi
