35、ngF1979 1735.4 Apparatus: ApparatusThis test method shall be conducted using a test fixture as shown in Fig. 2. The tensile bars7 usedin the test shall be molded of clear 121 grade Lexan8, polycarbonate (Fig. 3).5.5 Procedure:5.5.1 Test 3 separate tensile bars for each type of paint being tested. Te

36、st 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 tensile bar into each of the two control

37、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), which induces a 1.0 % strain orappro

38、ximately 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. Invertingthe test fixture is one method of ensurin

39、g 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 bars for cracks by holding the bars vert

40、ically 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 (0.112 in.) in length, and cracks longer

41、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.5.7 Precision and BiasNo information is presented about either the precision or bias of this test method since

42、this test methodis nonquantitative.6. Paintball Impact Breakage Test6.1 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 propelling device at a target,within the p

43、arameters of this specification, to test for the breakage of the paintballs upon the target.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

44、 its outer shell can split open and allow its fill tomark the player. This test method 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 thebreak

45、age of paintballs by impacting a target at a velocity common in the game of paintball.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 co

46、mplies withSpecification F2272. Each shotsshots muzzle velocity shall be measured and if not within tolerance, that impact is not valid.6.5.2 In the case of a laboratory environment this test may be performed using an air cannon to launch the paintballs, as longas the velocity specification of 6.5.1

47、 and barrel specifications of Specification F2272 are met.7 The sole source of supply of the apparatus known to the committee at this time is Hi Tech Mold and Tool Inc., 1520 East St., Pittsfield, MA 01201.
