All ten of thepaintballs that impact the target shall break upon impact.

14、3.7 Environmental SafetyPaintballs shall not contain en-vironmentally hazardous or toxic substances as defined inCERCLA2Regulations 40CFR302.4; SARA Toxic ChemicalList3Section 313; Clean Air Act4, Section 112B; and RCRARegulations540FRR261.24 through 40CFR261.33.TEST METHODS4. Paintball Compatibilit

15、y 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 involvesbending polycarbonate tensil

16、e 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 provides ameans to help determin

17、e 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 conducted using atest fixture

24、Bar Shown Without WrappingFIG. 3 Tensile BarF1979092polyethylene 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 evaporation.4.5.3 Bend the bagged tensile bars between the two stops onthe test fixture (F

25、ig. 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 paintballfill material shall be in contact with the center of the tensilebars. Inverting

26、the test fixture is one method of ensuring thiscontact. Wrapping the bag snugly around the tensile bars isanother proven 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 ba

27、rs 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.If either of the tensile bars used in the control test exhibit acrack of 3 mm (0.112

28、 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 bars.4.7 Precision and BiasNo information is presented abouteither the precision o

Paintball Impact Breakage Test5.1 ScopeThis test 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

30、, within theparameters of this specification, to test for the breakage of thepaintballs upon the target.5.3 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

31、 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 conditions common inthe game of paintball. This test method provides a means ofidentifying t

32、he breakage of paintballs by impacting a target ata velocity common in the game of paintball.5.4 SamplingSelect 30 paintballs 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

33、6 20ft/s). Each muzzle velocity shall be measured and if not withintolerance, that impact is not valid.5.5.2 Equipment employed to measure the speed of the testpaintball shall be accurate to within 60.5 m/s (620 ft/s)muzzle velocity.5.6 Conditioning:5.6.1 All impact testing shall be done using paint

34、ballsmanufactured 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 their original sealedcontainer for at least4hatthehumidity and tem
