A

2、 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 paintball markers, which pro-pel a paintball by means of energy released by compressed air,compressed gas or

3、 a combination thereof.1.2 LimitationsThis specification does not cover non-recreational paintball markers, for example, those used by lawenforcement, scientific, military or theatrical entities.1.3 The values stated in SI units are to be regarded as thestandard; the inch-pound units in parentheses

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

7、 pump or bolt 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 inta

8、ct paintball discharging from the marker or leavingthe confines of the barrel blocking device. The device is oftenreferred to as a barrel plug.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 cautionary statementthe warning outlined in Sec-tion 8 of this standard and noted in Specification F 2041, whichis to be placed on paintball markers, packaging and literature.3.1.7 disabling devicea device which, when activated,disables a part of the paintball marker, usually the t

10、rigger, 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 th

11、e “off”position renders the marker inoperable.3.1.8 discharge modea mode that controls the number ofpaintballs discharged per trigger cycle.3.1.9 enhanced trigger mode markera paintball markerthat at some point discharges more than one paintball pertrigger cycle. This includes markers that “store” t

12、he number oftrigger pulls and discharge more than one paintball at somepoint.3.1.10 feed mechanisma mechanism that stores, trans-ports and facilitates the loading of paintballs. It may be gravity,mechanically or air assisted or automatic in its actions.3.1.11 fully-automatic mode markera marker that

13、 dis-charges when the triggering device is actuated and continues todischarge until the trigger returns to its reset or recycleposition.3.1.12 hoppera device used with a paintball marker tostore paintballs.1This specification is under the jurisdiction of ASTM Committee F08 on SportsEquipment and Fac

Performance Requirements7.1 Marker FunctionThe cocking or pumping mechanismof a paintbal

36、l marker shall not cause a marker to dischargeunintentionally while a marker is being 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, ora combinati
