Significance and Use4.1 This specification establishes performance requirements and test methods for paintball markers.4.2

32、 This specification identifies the minimum warnings and instructions that are to be provided in literature, on labels, onpackaging and on the marker itself.5. Conformance5.1 Paintball markers shall not, either by label or other means, indicate conformance with this specification unless, at the timeo

33、f manufacture, they conform with all applicable requirements contained herein.6. General Requirements6.1 LiteratureLiterature shall be provided with each paintball marker and shall include, as applicable, the instructions,cautionary statements and safety tips specified in Section 8.6.2 Packaging:6.2

34、.1 Packaging shall be labeled in a prominent and conspicuous manner in accordance with the provisions of 8.5.6.2.2 All paintball markers that include a barrel must be packaged with a barrel blocking device.6.3 FinishThe exposed edges of all paintball markers shall be smooth and free of sharp edges a

35、nd burrs. The exposed surfaceof all wood parts shall be smooth and free of splinters.6.4 Shipping:6.4.1 Each paintball marker shall be shipped in an unloaded and degassed condition.6.4.2 All paintball markers must shoot at a velocity under 91.44 m/s (300 ft/s) at the time of shipment at SATP.6.5 Des

36、ign:6.5.1 All paintball markers with an exposed trigger shall have a trigger guard.6.5.2 All paintball markers intended to be used with refillable cylinders shall be able to withstand input pressure of threethousand pounds per square inch 207 bar (3000 psi) without catastrophic failure. Leaking in a

37、 manner which would not cause injuryto the operator shall not constitute failure.6.5.3 A markers performance may not be enhanced, including but not limited to increasing the markers velocity, without theuse of tools or the need for disassembly. In the event that a marker requires an internal switch,

38、 jumper or other device to be setprior to using outside adjustments, it will be considered to meet this requirement provided that tools or disassembly are requiredto access the switch, jumper or similar device.6.5.4 All paintball markers shall only operate in pump, semi-automatic, modified fully aut

Performance Requirements7.1 Marker FunctionThe cocking or pumping mechanism of a paintball marker shall not cause a marker to dischargeunintentionally while a marker is being cocked in

40、accordance with the manufacturers instructions. This does not limit the use of“auto-triggers.” Markers shall be pump, semi-automatic, modified fully automatic mode 1, or modified burst mode 2, responsetrigger, or a combination thereof, as defined in this standard.7.2 Gas Propellant Source RetentionM

41、arkers shall be designed so that a gas propellant source does not inadvertently ejectfrom the marker during use or otherwise.F2272 1237.3 Disabling DeviceDisabling devices shall be provided on all paintball markers and all such devices can be ended whetheror not the marker is cocked. All such device

42、s shall be clearly marked to indicate the “safe” and “fire” or “on” and “off” positionsin accordance with 8.6.4.All such devices shall be capable of preventing the markers from being discharged when a weight of 13.6kg (30 lb) is applied to the trigger. Tests shall be conducted in accordance with 8.3

43、.7.4 Accidental DischargeMarkers should not accidentally discharge when exposed to a moderate jolt in accordance with 8.3.8. Test Methods8.1 No precision statement on any of the following test methods is available at this time.8.2 Disabling Device Test:8.2.1 SignificanceThis method determines if the

44、 disabling device will withstand a 13.6 kg (30 lb) applied weight withoutfailure, causing the marker to discharge.8.2.2 ApparatusA trigger weight system having a 13.6 6 0.02 kg (30 6 0.05 lb) weight. Arrange the weight system so thatthe weights can be picked up by the trigger of the marker with the

45、marker in a vertical position, muzzle up. (Aspring gage, capableof measuring the trigger force, can be used instead of weight system.)8.2.3 Test SpecimenThe test specimen shall consist of a new paintball marker, selected in accordance with the manufacturersusual quality assurance practices.8.2.4 Pro

46、cedure:8.2.4.1 Conduct the test at SATP.8.2.4.2 Conduct all tests without paintballs in the marker.8.2.4.3 Place disabling device in “safe” position or the electronic switch in the “off” position.8.2.4.4 Apply a 13.6 kg (30 lb) load at the center point of the trigger for 30 s with the load applied t
