ASTM F2278-19(2023) PDF

SIGNIFICANCE AND USE 4.1 This method is performed to evaluate if paintball barrier netting will prevent an intact paintball or shell fragments exceeding 3 by 5 mm (0.118 by 0.197 in.) from passing through the netting. 4.2 This test method provides accurate results about the current effectiveness of the test specimen when field-tested in an existing installation. Laboratory results are particularly useful for testing the relative effectiveness of multiple test specimens. 4.3 The results stemming from the use of this test method may be used to evaluate the effectiveness of paintball barrier netting represented by the test specimen for use in delineating “goggles-on” areas found at paintball playing fields. 4.4 The base procedure outlined below is applicable to “field-testing.” Additional requirements for “laboratory” testing are noted. SCOPE 1.1 This test method is designed to evaluate paintball barrier netting that may be used to delineate playing fields, chronograph areas, target ranges, and other “goggle-on” areas of an active paintball site. An apparatus is suggested to evaluate paintball barrier netting in a laboratory. On site testing does not require such an apparatus. 1.2 This standard is designed to be used in conjunction with Guide F2184. 1.3 The values stated in SI units are to be regarded as the standard; the inch-pound units in parentheses are provided 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
