1、Designation:F227810a(Reapproved 2014)An American National StandardStandard Test Method forEvaluating Paintball Barrier Netting1This standard is issued under the fixed designation F2278;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,
2、the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis standard is intended to provide a basic test method that would allow the user to determine theeffectivene
3、ss of paintball barrier netting.The use of safe paintball barrier netting at paintball playingfacilities is critical to protect non-players from accidental impact of a paintball.This specification is written within the current state-of-the-art of paintball barrier nettingtechnology.The intent is to
4、revise this specification whenever substantive information becomesavailable which justifies revising existing requirements or adding new requirements.1.Scope1.1 This test method is designed to evaluate paintball barriernetting that may be used to delineate playing fields,chrono-graph areas,target ra
