Designation:F308514An 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 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.Abarrel 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 willsubstantially 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 necessitatingperformance 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 substantiveinformation 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 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 of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2F2654 Specification for Low EnergyAir Gun(LEAG)Warn-ingsF2679 Specification for 6 mm Projectiles Used with LowEnergy Air GunsF2748 Specification for Low Energy Air Guns(Less Than 1Joule)3.Terminology3.1 Definitions of Terms Specific to This StandardAir SoftGun Terms:3.1.1 air soft gun,na device specifically designed todischarge air soft projectiles conforming to SpecificationsF2654 and F2748.3.1.1.1 DiscussionThese devices may operate in a com-bination of discharge modes depending on the design.3.1.2 air soft projectile,na spherical ball,commonly witha diameter of approximately 6 mm made of a molded polymerand designed to be expelled from an air soft gun and conform-ing to Specification F2679.3.1.3 barrel,nthat portion of an air soft gun throughwhich the 6 mm projectile is discharged.3.1.4 barrel blocking device,na safety device that pre-vents an air soft from being accidentally discharged from themuzzle of the air soft gun or leaving the confines of the barrelblocking device.3.1.5 clearing rod,na device used to assist in freeing airsoft projectiles jammed or trapped inside an air soft gun barrel.3.1.6 discharge mode,na mode that controls the numberof air soft projectiles discharged per trigger cycle.1This specification is under the jurisdiction of ASTM Committee F08 on SportsEquipment,Playing Surfaces,and Facilities and is the direct responsibility ofSubcommittee F08.27 on Airsoft.Current edition approved May 1,2014.Published May 2014.DOI:10.1520/F3085-14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.7 fully-automatic air soft gun,nan air soft gun thatdischarges when the triggering device is actuated and continuesto discharge until the trigger returns to its reset or recycleposition.3.1.8 muzzle,nthe end of the barrel at which the air softprojectile exits the barrel.3.1.9 muzzle diameter,nthe inside barrel diameter asmeasured at the muzzle.3.1.10 semi-automatic air soft gun,na semi-automatic airsoft gun discharges one time with each trigger cycle.3.1.11 single shot air soft gun,nan air soft gun thatrequires the operator to manually cock or engage the sear of theair soft gun before each shot by a means of a pump,bolt,lever,cocking handle,or similar device.3.1.12 standard ambient temperature(SAT),nused todescribe a substance at a temperature of 25 6 2C(77 6 4F).4.Significance and Use4.1 This specification establishes performance requirementsand test methods to provide a reasonable degree of safety in th
