Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 auto-triggera trigger which, when held in the dis-charge position, will automatically cause the paintball markerto discharge when the pump or bolt
7、 action is manipulated.3.1.2 backstopan object intended to stop a paintball.3.1.3 barrelthat portion of a paintball marker throughwhich the paintball is discharged.3.1.4 barrel blocking devicea muzzle blocking safetydevice which, when properly installed, reduces the likelihoodof an intact paintball
8、discharging from the marker or leavingthe confines of the barrel blocking device. The device is oftenreferred to as a barrel plug or barrel bag.3.1.5 burst mode markera burst mode marker may dis-charge two or more times per trigger cycle or may dischargetwo or more times with the pull and release of
9、 the trigger.3.1.6 caliberthe term used to refer to the size of apaintball projectile.

11、e trigger, toprevent unintentional discharges and must be released to allowthe marker to be discharged by the movement of the trigger.The device is sometimes referred to as the “safety,” “safetybutton,” or “safety lever.” An electronic on/off switch isconsidered a disabling device when placing it in
12、 the “off”position renders the marker inoperable.3.1.10 discharge modea mode that controls the number ofpaintballs discharged per trigger cycle.3.1.11 enhanced trigger mode markera paintball markerthat at some point discharges more than one paintball pertrigger cycle. This includes markers that “sto
13、re” the number oftrigger pulls and discharge more than one paintball at somepoint.1This specification is under the jurisdiction of ASTM Committee F08 on SportsEquipment and Facilities and is the direct responsibility of Subcommittee F08.24 onPaintball and Equipment.Current edition approved May 1, 20

35、e. Leaking in a manner which would notcause injury to the operator shall not constitute failure.6.5.3 Amarkers performance may not be enhanced, includ-ing but not limited to increasing the markers velocity, withoutthe use of tools or the need for disassembly. In the event thata marker requires an in
36、ternal switch, jumper or other device tobe set prior to using outside adjustments, it will be consideredto meet this requirement provided that tools or disassembly arerequired to access the switch, jumper or similar device.6.5.4 All paintball markers shall only operate in pump,semi-automatic, modifi

Performance Requirements7.1 Marker FunctionThe cocking or pumping mechanismof a paintball marker shall not cause a marker to dischargeunintentionally while a marker is being
38、cocked in accordancewith the manufacturers instructions. This does not limit theuse of “auto-triggers.” Markers shall be pump, semi-automatic,modified fully automatic mode 1, or modified burst mode 2,response trigger, or a combination thereof, as defined in thisstandard.7.2 Gas Propellant Source Ret
39、entionMarkers shall bedesigned so that a gas propellant source does not inadvertentlyeject from the marker during use or otherwise.7.3 Disabling DeviceDisabling devices shall be providedon all paintball markers and all such devices can be endedwhether or not the marker is cocked. All such devices sh
40、all beclearly marked to indicate the “safe” and “fire” or “on” and“off” positions in accordance with 8.6.4. All such devices shallbe capable of preventing the markers from being dischargedwhen a weight of 13.6 kg (30 lb) is applied to the trigger. Testsshall be conducted in accordance with 8.3.7.4 A
41、ccidental DischargeMarkers should not accidentallydischarge when exposed to a moderate jolt in accordance with8.3.8. Test Methods8.1 No precision statement on any of the following testmethods is available at this time.8.2 Disabling Device Test:8.2.1 SignificanceThis method determines if the disablin

Arrange the weight system sothat the weights can be picked up by the trigger of the markerwith the marker in a
43、vertical position, muzzle up. (A springgage, capable of measuring the trigger force, can be usedinstead of weight system.)8.2.3 Test SpecimenThe test specimen shall consist of anew paintball marker, selected in accordance with the manu-facturers usual quality assurance practices.F2272 1138.2.4 Proce
