Designation:F257406(Reapproved 2014)An American National StandardStandard Specification forLow Velocity Projectile Marker1This standard is issued under the fixed designation F2574;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.1.Scope1.1 This specification covers low velocity projectile markers(herein referred to as LVP marker)that propel a low velocityresilient material projectile(herein referred to as LVRMprojectile as defined in Specification F2573)by means ofenergy released by compressed air,compressed gas,or acombination thereof,with velocity not to exceed 53.34 m/s(175 ft/s).1.2 LVRM projectiles are made of a resilient material andhave a diameter no smaller than 20 mm(0.7874 in)and nogreater than 30 mm(1.18 in.).The hardness of the LVRMprojectile is to be no greater than 75 Shore 00.The weight ofthe LVRM projectile is not to exceed 4.0 g.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.1.4 The following precautionary caveat pertains only to thetest method portion,Section 8,of this specification.Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2F1750 SpecificationforPaintballMarker Threaded-Propellant Source InterfaceF1776 Specification for Eye Protective Devices for PaintballSportsF2573 Specification for Low Velocity Resilient MaterialProjectile2.2 ANSI Standard:3Z535.1 Safety Color Code3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 auto-triggertrigger that,when held in the dischargeposition,will automatically cause the LVP marker to dischargewhen the pump or bolt action is manipulated.3.1.2 backstopobject intended to stop a LVRM projectile.3.1.3 barrelthat portion of a LVP marker through whichthe LVRM projectile is discharged.3.1.4 barrel blocking devicemuzzle blocking safety de-vice that when properly installed,reduces the likelihood of anintact LVRM projectile discharging from the marker or leavingthe confines of the barrel blocking device.The device is oftenreferred to as a barrel plug or sleeve.3.1.5 cautionary statementwarning outlined in Section 9that is to be placed on LVP markers,packaging,and literature.3.1.6 disabling devicedevice that,when activated,dis-ables a part of the LVP marker,usually the trigger,to preventunintentional discharges and must be released to allow themarker to be discharged by the movement of the trigger.Thedevice is sometimes referred to as the“safety,”“safety button,”or“safety lever.”An electronic on/off switch is considered adisabling device if when placed in the“off”position,it rendersthe marker inoperable.3.1.7 discharge modemode that controls the number ofLVRM projectiles discharged per trigger cycle.3.1.8 feed mechanismmechanism that stores,transports,and facilitates the loading of LVRM projectiles.It may begravity,mechanically or air assisted,or automatic in its actions.3.1.9 hopperdevice used with a LVP marker to storeLVRM projectiles.3.1.10 impact testerdevice used to test for accidentaldischarges of LVP marker.See Fig.1.3.1.11 low velocity resilient material projectileobject pro-pelled by means of a discharge mechanism,capable of storingand releasing energy under the control of the operator,com-prised of a resilient material,and has a diameter no smaller1This specification is under the jurisdiction of ASTM Committee F08 on SportsEquipment,Playing Surfaces,and Facilities and is the direct responsibility ofSubcommittee F08.24 on Paintball and Equipment.Current edition approved May 1,2014.Published September 2014.Originallyapproved in 2006.Last previous edition approved in 2010 as F2574 06(2010).DOI:10.1520/F2574-06R14.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 than 20 mm(0.7874 in)and no greater than 30 mm(1.18 in.).The hardness of the low velocity resilient material projectile isto be no greater than 75 Shore 00.The weight is not to exceed4.0 g.3.1.12 low velocity projectile markerdevice specificallydesigned to discharge low velocity resilient material projec-tiles.3.1.13 pump mode markermarker that requires the opera-tor to manually cock or engage the sear of the mark
