1. Scope
1.1 This specification establishes testing procedures and critical characteristics for projectiles, which define whether they are suitable for use in the sport of paintball. Furthermore, the specification establishes minimum warning and package labeling requirements to help ensure that the paintballs are used in a safe manner and that the risk of injury is reduced. 1.2 This specification does not cover non-recreational paintballs, for example, those used by law enforcement, scientific, military, or theatrical entities. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions ofTerms Specific to This Standard: 3.1.1 caliber, n—the term used to refer to the size of a paintball projectile. Related to the measurement of the diam- eter of the paintball. 3.1.2 cubic centimeter, n—commonly used unit of volume extending the derived SI-unit cubic meter and corresponding to the volume of a cube measuring 1 × 1 × 1 cm. 3.1.2.1 Discussion—The mass of one cubic centimeter of water is approximately equal to 1 g. 3.1.3 fill material, n—liquid inside of a paintball. 3.1.4 paintball, n—a projectile designed to be expelled from a paintball marker meeting the requirements of Specification F2272. 3.1.4.1 spherical paintball, n—a round projectile, with a diameter and weight as defined in Table 1, comprised ofa shell and a fill material, and designed to be expelled from a paintball marker. 3.1.4.2 shaped paintball, n—non-spherical cylindrical shaped projectile with a hemispherical front surface, and a diameter, length, and weight as defined in Table 2, comprised of a shell and a fill material, and designed to be expelled from a paintball marker most commonly with a magazine style feed. 3.1.5 paintball marker, n—device specifically designed to discharge paintballs which conforms to Specification F2272. 3.1.6 shell—rigid to semi-rigid frangible material (generally of gelatin) that encapsulates or contains the fill material of a projectile used in the sport of paintball.
4.2 Paintball Fill Compatibility With Polycarbonate— When tested in accordance with Section 5, no more than one of the three polycarbonate tensile bars exposed to the fill material shall develop a visible crack that is greater than 6.5 mm (0.256 in.) in length. 4.3 Maximum Weight—A paintball shall not weigh more than as defined in Table 1 and Table 2 based on the caliber and type of the paintball. 4.4 Fill Color Limitations—A paintball shall not contain fill material with a color mimicking that of human blood. 4.5 Diameter of a Spherical Paintball—The diameter of a spherical paintball shall be measured around both the polar axis and seam; both measurements shall be within the minimum and maximum range as defined in Table 1, based on the caliber of the paintball. 4.6 Diameter of Shaped Paintball—The diameter of a shaped paintball as measured around the largest section of the cylinder of the sample shall measure within the minimum and maximum range as defined in Table 2 based on the caliber of the shaped paintball. 4.7 Length of Shaped Paintball—The length of the shaped paintball as measured along the overall length of the object shall measure within the minimum and maximum range as defined in Table 2 based on the caliber of the shaped paintball. 4.8 Impact Breakage—The impact breakage of the paintball shall be tested in accordance with Section 6. All ten of the paintballs that impact the target shall break upon impact.
