3、 paintballs. The goal is to provide paintball manufacturers with a specification that promotessafety in the sport of paintball.1. Scope1.1 This specification establishes testing procedures andcritical characteristics of 0.68 caliber paintballs which helpdefine whether a paintball is suitable for use
4、 in the sport ofpaintball. Furthermore, the specification establishes minimumwarning and package labeling to help ensure that the paintballsare used in a safe manner and that the risk of injury is reduced.1.2 This specification does not cover non-recreational paint-balls, for example, those used by
5、law enforcement, scientific,military, or theatrical entities.1.3 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.4 This specification does not purport to address all of thesafety issues associated with the sport of paintball.

17、4. Paintball Compatibility with Polycarbonate4.1 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.4.2 Summary of Test MethodThis test method involvesben
18、ding 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.4.3 Significance and UseThis test method provide
19、s ameans to help determine the suitability of specific paintball fillmaterial for use in the sport of paintball. This test methodprovides a relative indicator of the reaction that a polycarbon-ate lens would have to the paintball fill material being tested.4.4 ApparatusThis test method shall be cond
20、ucted using atest fixture as shown in Fig. 1. The tensile bars6used in the testshall be molded of clear 121 grade Lexan7, polycarbonate (Fig.2).4.5 Procedure:4.5.1 Test 3 separate tensile bars for each type of paint beingtested. Test a total of 2 tensile bars in the control test using tapwater.4.5.2
21、 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 bag around the bar so that the fillo
22、r water is in contact with the center of the bar, and seal the bagto prevent fill leakage or evaporation.4.5.3 Bend the bagged tensile bars between the two stops onthe test fixture (Fig. 1), which induces a 1.0 % strain orapproximately 175.75 k/cm2(2500 psi). Store the bent tensilebars in the test f
23、ixture 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 around the tensile bars isanother pro
24、ven method.4.5.4 After 7 days, remove the tensile bars from the testfixture and rinse with clean tap water. Dry the tensile bars andinspect for cracks.4.6 ReportInspect the tensile bars for cracks by holdingthe bars vertically facing either direct sunlight or a bright lightsource. Tilt the bars slig
25、htly 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 three tensile barsexposed to the fil
26、l material, the test may be considered invalidand performed again using a different batch of tensile bars.4.7 Precision and BiasNo information is presented abouteither the precision or bias of this test method since this testmethod is nonquantitative.5. Paintball Impact Breakage Test5.1 ScopeThis te
27、st method is intended to determine theability of the paintballs to burst upon impact.5.2 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 thepaintballs upon the target.5.3 Significa
28、nce 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. This test method provides ameans of i
29、dentifying 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 paintball.5.4 SamplingSelect 30 pa
30、intballs at random from the lotof paintballs being tested.5.5 Apparatus:5.5.1 The propelling device shall be capable of hurlingpaintballs horizontally at a speed of 85.3 6 6 m/s (280 6 20ft/s). Each muzzle velocity shall be measured and if not withintolerance, that impact is not valid.6The sole sour

33、.6 Conditioning:5.6.1 All impact testing shall be done using paintballsmanufactured within the previous 8 months.5.6.2 Paintball storage and the non-test handling shall bedone at a relative humidity below 65 % and a temperaturebetween 19C (66F) and 27C (80F).5.6.3 Paintballs shall be conditioned in
34、their original sealedcontainer for at least4hatthehumidity and temperaturespecified in 5.6.2.5.6.4 The testing shall be conducted at the temperaturesspecified in 5.6.2 and shall be completed within 10 min afterremoval of the paintball from the sealed container. Thepaintball container shall be reseal
35、ed immediately after eachgroup of paintballs is removed.5.7 Procedure:5.7.1 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 propellingdevice. Width and length of the target to be of a size that
36、 thelaboratory determines necessary to hit the target.5.7.2 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).5.7.3 Impact the plywood target with ten paintballs at anangle nominally normal to th
37、e target and at the distance inaccordance with 5.7.1. Only those shots that are within thevelocity tolerance in accordance with 5.7.2 shall be used in thistest method.5.8 Precision and BiasNo information is presented abouteither the precision or bias of this test method since this testmethod is nonq
