Paintball Compatibility with Polycarbonate5.1 ScopeThis test method is intended to determine thecompatibility of the paintball fill with polycarbonate, theplastic material currently universally used for protective eye-wear lenses in paintball.5.2 Summary o
18、f Test MethodThis test method involvesbending polycarbonate tensile bars in a test fixture while thesebars are exposed to the paintball fill material and observinghow these tensile bars react to the fill. A control test is alsoconducted using tap water in place of the paintball fill material.5.3 Sig

Test a total of 2 tensile bars in th
27、e control test using tapwater.5.5.2 Place the fill from 4 paintballs of the tested paint intoa polyethylene bag, (the zip-lock variety works well), alongwith one tensile bar. Place 15 mL (12 oz) of tap water, alongwith one tensile bar into each of the two control samplepolyethylene bags. Wrap each b
28、ag around the bar so that the fillor water is in contact with the center of the bar, and seal the bagto prevent fill leakage or evaporation.5.5.3 Bend the bagged tensile bars between the two stops onthe test fixture (Fig. 2), which induces a 1.0 % strain orapproximately 175.75 k/cm2(2500 psi). Store
29、 the bent tensilebars in the test fixture at room temperature 23 6 2C (73 63.5F) for 7 days. During the entire 7-day period, the paintballfill material shall be in contact with the center of the tensilebars. Inverting the test fixture is one method of ensuring thiscontact. Wrapping the bag snugly ar
30、ound the tensile bars isanother proven method.5.5.4 After 7 days, remove the tensile bars from the testfixture and rinse with clean tap water. Dry the tensile bars andinspect for cracks.5.6 ReportInspect the tensile bars for cracks by holdingthe bars vertically facing either direct sunlight or a bri
31、ght lightsource. Tilt the bars slightly to highlight any cracks. Recordand report the length of the longest crack on each tensile bar.If either of the tensile bars used in the control test exhibit acrack of 3 mm (0.112 in.) in length, and cracks longer than 6.5mm have also been found in two of the t
32、hree tensile barsexposed to the fill material, the test may be considered invalidand performed again using a different batch of tensile bars.5.7 Precision and BiasNo information is presented abouteither the precision or bias of this test method since this testmethod is nonquantitative.6.

33、mpact Breakage Test6.1 ScopeThis test method is intended to determine theability of the paintballs to burst upon impact.6.2 Summary of Test MethodThis test method involvesshooting paintballs from a paintgun at a target, within theparameters of this specification, to test for the breakage of thepaint
34、balls upon the target.6.3 Significance and UseIn the sport of paintball, a playerwho is marked with fill of a paintball is eliminated from thegame, and thus it is desirable that a paintball be designedwithin parameters such that its outer shell can split open andallow its fill to mark the player. Th
35、is test method provides ameans of identifying the breakage ability of paintballs withinparameters that reasonably approximate conditions common inthe game of paintball. This test method provides a means ofidentifying the breakage of paintballs by impacting a target ata velocity common in the game of
36、 paintball.6.4 SamplingSelect 30 paintballs at random from the lotof paintballs being tested.6.5 Apparatus:6.5.1 A paintball marker capable of hurling paintballs hori-zontally at a speed of 85.3 6 6 m/s (280 6 20 ft/s) thatcomplies with Specification F2272. Each shots muzzle veloc-ity shall be measu
37、red and if not within tolerance, that impact isnot valid.6.5.2 Equipment employed to measure the speed of the testpaintball shall be accurate to within 60.5 m/s (620 ft/s)muzzle velocity.6.6 Conditioning:6.6.1 All impact testing shall be done using paintballsmanufactured within the previous 8 months
38、.6.6.2 Paintball storage and the non-test handling shall bedone at a relative humidity below 65 % and a temperaturebetween 19C (66F) and 27C (80F).6.6.3 Paintballs shall be conditioned in their original sealedcontainer for at least4hatthehumidity and temperaturespecified in 6.6.2.6.6.4 The testing s
39、hall be conducted at the temperaturesspecified in 6.6.2 and shall be completed within 10 min afterremoval of the paintball from the sealed container. Thepaintball container shall be resealed immediately after eachgroup of paintballs is removed.6.7 Procedure:6.7.1 Secure a plywood target with a minim
40、um thickness of10-mm vertically at a distance of 24.4 6 0.3-m (80 6 1-ft)linear ground distance from the muzzle of the paintball marker.Width and length of the target to be of a size that the laboratorydetermines necessary to hit the target.6.7.2 Measure the velocity of the paintball within 1.0 m (3
41、.3ft) of the muzzle of the propelling device. Paintball velocityshall be 85.3 6 6 m/s (280 6 20 ft/s).6.7.3 Impact the plywood target with ten paintballs at anangle nominally normal to the target and at the distance inaccordance with 6.7.1. Only those shots that are within thevelocity tolerance in a
42、ccordance with 6.7.2 shall be used in thistest method.6.8 Precision and BiasNo information is presented abouteither the precision or bias of this test method since this testmethod is nonquantitative.7.
