25、ar 121 grade Lexan8, polycarbonate (Fig. 3).5.5 Procedure:5.5.1 Test 3 separate tensile bars for each type of paint beingtested. Test a total of 2 tensile bars in the control test using tapwater.5.5.2 Place the fill from 4 paintballs of the tested paint intoa polyethylene bag, (the zip-lock variety
26、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 bag 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 evapora
27、tion.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 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 paintb
28、allfill 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 around the tensile bars isanother proven method.5.5.4 After 7 days, remove the tensile bars from the testfixture and rinse with clean tap
29、 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 bright lightsource. Tilt the bars slightly to highlight any cracks. Recordand report the length of the longest crack on each tensile bar.I
30、f 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 three tensile barsexposed to the fill material, the test may be considered invalidand performed again using a different batch of tensile
31、 bars.5.7 Precision and BiasNo information is presented abouteither the precision or bias of this test method since this testmethod is nonquantitative.6. Paintball Impact Breakage Test6.1 ScopeThis test method is intended to determine theability of the paintballs to burst upon impact.6.2 Summary of
32、Test MethodThis test method involvesshooting paintballs from a paintgun at a target, within theparameters of this specification, to test for the breakage of thepaintballs upon the target.6.3 Significance and UseIn the sport of paintball, a playerwho is marked with fill of a paintball is eliminated f
33、rom 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. This test method provides ameans of identifying the breakage ability of paintballs withinparameters that reasonably approximate condition
34、s 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 paintball.6.4 SamplingSelect 30 paintballs at random from the lotof paintballs being tested.6.5 Apparatus:6.5.1 A paintball marker cap
35、able 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 measured and if not within tolerance, that impact isnot valid.6.5.2 Equipment employed to measure the speed of the testpaintball shall be ac
36、curate 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.6.6.2 Paintball storage and the non-test handling shall bedone at a relative humidity below 65 % and a temperaturebetween 19C (66F) an
37、d 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 shall be conducted at the temperaturesspecified in 6.6.2 and shall be completed within 10 min afterremoval of the paintball from the sea
38、led 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 minimum 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
39、.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 (3.3ft) 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 w
40、ith 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 accordance with 6.7.2 shall be used in thistest method.6.8 Precision and BiasNo information is presented abouteither the precision or bi
