(Specification)Standard Specification for Low Velocity Projectile Marker
Standard Specification for Low Velocity Projectile Marker
ABSTRACT
This specification covers low velocity projectile (LVP) markers that eject a low velocity resilient material (LVRM) projectile using compressed air, compressed gas, or a combination of both. Included in this specification are performance requirements and test methods for LVP markers as well as the minimum warnings and instructions that need to be provided in literature, on labels, on packaging, and on the marker itself. The LVP markers shall be manufactured to operate only in semi-automatic or pump mode and with exposed edges that shall be smooth and free of sharp edges and burrs. LVP markers shall be provided with a disabling device which shall keep it from firing and with a provision against accidental discharge. The markers shall undergo tests for disabling device, accidental discharge, barrel blocking device, and impact, and shall conform to the requirements specified.
SCOPE
1.1 This specification covers low velocity projectile markers (herein referred to as LVP marker) that propel a low velocity resilient material projectile (herein referred to as LVRM projectile as defined in Specification F2573) by means of energy released by compressed air, compressed gas, or a combination thereof, with velocity not to exceed 53.34 m/s (175 ft/s).
1.2 LVRM projectiles are made of a resilient material and have a diameter no smaller than 20 mm (0.7874 in) and no greater than 30 mm (1.18 in.). The hardness of the LVRM projectile is to be no greater than 75 Shore 00. The weight of the LVRM projectile is not to exceed 4.0 g.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4 The following precautionary caveat pertains only to the test method portion, Section 8, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

application of the load and does not discharge upon the disengagement of the disabling device, and the disabling device and trigger
function properly after testing.
8.3 Accidental Discharge Test:
8.3.1 Significance—LVP markers should not discharge while their disabling device is disengaged.
8.3.2 Test Specimen—The test specimen shall consist of a new LVP marker, selected in accordance with the manufacturer’s
usual quality assurance practices.
8.3.3 Procedure:
8.3.3.1 Conduct the test at SATP.
8.3.3.2 Attach a properly charged propellant source if required in accordance with the manufacturer’s instructions. Test
discharge the marker.
8.3.3.3 Leave the marker in the ready to discharge condition.
8.3.3.4 Suspend marker using a sling (see Fig. 2).
8.3.3.5 Place the cocked impact tester (see Fig. 1) against the side of the marker centered on the grip frame directly behind the
center point of the trigger with the impact tester firmly affixed to an immobile surface.
8.3.3.6 Release the impact tester and observe if the marker discharges.
8.3.3.7 Repeat by impacting the marker on the following axis:
(1) 180 degrees to the first impact.
(2) The front of the barrel aligned with the barrel’s axis.
(3) The rearmost point of the marker aligned with the barrel’s axis.

8.3.3.8 The marker fails if it discharges on any impact.
8.4 Barrel Blocking Device Requirement:
8.4.1 Significance—All LVP markers that include a barrel must be packaged with a barrel blocking device.
8.4.2 Test Specimen—The test specimen shall consist of a new LVP marker packaged in the manufacturer’s original packaging.
8.4.3 Procedure—Open packaging and inspect for the presence of a barrel blocking device. Any package not containing a barrel
blocking device fails this requirement.
8.5 Impact Testing:
8.5.1 Significance—The test is intended to simulate situations in which possible damage can occur by reason of its falling or
other impact situations that may occur as a result of reasonably foreseeable abuse. After undergoing the appropriate test, the marker
shall be examined for damaged or fractured components or parts. The marker is not fit for use if damage or fracture is observed.
8.5.2 Apparatus:
8.5.2.1 Tile Floor Area—The impact medium shall consist of a 3 mm ( ⁄8 in.) nominal thickness of Type IV vinyl composition
tile, composition 1-asbestos free, as specified in Federal Specification SS-T-312B over at least a 64 mm (2.5 in.) thickness of
2 2
concrete. The impact area shall be at least 0.3 m (3 ft ).
8.5.2.2 Concrete Floor, on which to place the tiles.
8.5.2.3 Measure, 0.93 m (3 ft, 0.5 in.), to establish the height of the drop.
8.5.2.4 Projectiles, to fill the magazine or an equivalent.
8.5.3 Test Specimen—The test specimen shall consist of a new LVP marker selected in accordance with the manufacturer’s usual
quality assurance practic
