Significance and Use4.1 This method is performed to evaluate if paintball barrier netting will prevent an intact paintball or shell fragments exceeding3 by 5 mm (0.118 by 0.197 in.) from passing
17、through the netting.4.2 This test method provides accurate results about the current effectiveness of the test specimen when field-tested in anexisting installation. Laboratory results are particularly useful for testing the relative effectiveness of multiple test specimens.4.3 The results stemming
