This test method provides a relative indicator of the reaction that a polycarbonate
26、 lens would haveto the paintball fill material being tested.5.4 Apparatus:This test method shall be conducted using a test fixture as shown in Fig. 2. The tensile bars7 used in the test shall be moldedof clear 121 grade Lexan8, polycarbonate (Fig. 3).5.5 Procedure:5.5.1 Test 3 separate tensile bars
27、for each type of paint being tested. 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 into a polyethylene bag, (the zip-lock variety works well), along withone tensile bar. Place 15 mL (12 oz) of tap water, along with one te
28、nsile bar into each of the two control sample polyethylene bags.Wrap each bag around the bar so that the fill or water is in contact with the center of the bar, and seal the bag to prevent fill leakageor evaporation.5.5.3 Bend the bagged tensile bars between the two stops on the test fixture (Fig. 2
29、), which induces a 1.0 % strain orapproximately 175.75 k/cm2 (2500 psi). Store the bent tensile bars in the test fixture at room temperature 23 6 2C (73 6 3.5F)for 7 days. During the entire 7-day period, the paintball fill material shall be in contact with the center of the tensile bars. Invertingth
30、e test fixture is one method of ensuring this contact. Wrapping the bag snugly around the tensile bars is another proven method.5.5.4 After 7 days, remove the tensile bars from the test fixture and rinse with clean tap water. Dry the tensile bars and inspectfor cracks.5.6 ReportInspect the tensile b
31、ars for cracks by holding the bars vertically facing either direct sunlight or a bright light source.Tilt the bars slightly to highlight any cracks. Record and report the length of the longest crack on each tensile bar. If either of thetensile bars used in the control test exhibit a crack of 3 mm (0
32、.112 in.) in length, and cracks longer than 6.5 mm have also beenfound in two of the three tensile bars exposed to the fill material, the test may be considered invalid and performed again usinga different batch of tensile bars.7 The sole source of supply of the apparatus known to the committee at t

Paintball Impact Breakage Test
35、6.1 ScopeThis test method is intended to determine the ability of the paintballs to burst upon impact.6.2 Summary of Test MethodThis test method involves shooting paintballs from a paintgun at a target, within the parametersof this specification, to test for the breakage of the paintballs upon the t
36、arget.6.3 Significance and UseIn the sport of paintball, a player who is marked with fill of a paintball is eliminated from the game,and thus it is desirable that a paintball be designed within parameters such that its outer shell can split open and allow its fill tomark the player. This test method
37、 provides a means of identifying the breakage ability of paintballs within parameters thatreasonably approximate conditions common in the game of paintball. This test method provides a means of identifying thebreakage of paintballs by impacting a target at a velocity common in the game of paintball.
38、6.4 SamplingSelect 30 paintballs at random from the lot of paintballs being tested.6.5 Apparatus:6.5.1 Apaintball marker capable of hurling paintballs horizontally at a speed of 85.3 6 6 m/s (280 6 20 ft/s) that complies withSpecification F2272.

42、m thickness of 10-mm vertically at a distance of 24.4 6 0.3-m (80 6 1-ft) linearground 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 (
43、3.3 ft) of the muzzle of the propelling device. Paintball velocity shallbe 85.3 6 6 m/s (280 6 20 ft/s).6.7.3 Impact the plywood target with ten paintballs at an angle nominally normal to the target and at the distance in accordancewith 6.7.1. Only those shots that are within the velocity tolerance
44、in accordance with 6.7.2 shall be used in this test method.6.8 Precision and BiasNo information is presented about either the precision or bias of this test method since this test methodis nonquantitative.7.
