1、Designation: F 1979 04An American National StandardStandard Specification forPaintballs Used in the Sport of Paintball1This standard is issued under the fixed designation F 1979; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the
2、year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis specification sets forth a set of guidelines and testing procedures for the manufacturing of 0.68caliber
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.
6、 It is theresponsibility of the user of this specification to establishappropriate safety and health practices and to comply with allapplicable laws and regulations.2. Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 fillliquid inside of a paintball.2.1.2 paintballspherical ball,
7、commonly with a diameterof 17.3 mm (0.68 in.), comprised of a shell and a fill, anddesigned to be expelled from a paintball gun.2.1.3 paintball gundevice specifically designed to dis-charge paintballs.2.1.4 paintball markerdevice specifically designed to dis-charge paintballs. The device is sometime
8、s referred to as apaintball gun.2.1.5 shellrigid to semirigid material (generally of gela-tin) that encapsulates the fill of a paintball.3. General Requirements3.1 pH of Fill MaterialThe pH of the fill used in thepaintball shall measure between 4.5 and 7.5 as measured usinga 10 % solution of the fil
9、l in distilled water. Measurementsshall be made using a properly calibrated pH meter.3.2 Paintball Fill Compatibility With PolycarbonateWhen tested in accordance with Section 4, no more than one ofthe three polycarbonate tensile bars exposed to the fill materialshall develop a visible crack that is
10、greater than 6.5 mm (0.256in.) in length.3.3 Maximum WeightThe paintballs shall not weigh morethan 3.5 g.3.4 Fill Color LimitationsThe paintballs shall not containfill material with a color mimicking that of human blood.3.5 Diameter of PaintballThe diameter of the paintball asmeasured both polar and
11、 at the seam shall measure between16.5 mm (0.650 in.) and 18 mm (0.709 in.).3.6 Impact BreakageThe impact breakage of the paintballshall be tested in accordance with Section 5. All ten of thepaintballs that impact the target shall break upon impact.3.7 Environmental SafetyPaintballs shall not contai

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
