ASTM F2271-11

Standard Specification for Paintball Marker Barrel Blocking Devices

SCOPE
1.1 This specification covers paintball barrel blocking devices that may be inserted or otherwise function to prevent a paintball from leaving the muzzle or the confines of the barrel blocking device intact.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are provided for information only.
1.3 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 and health practices and determine the applicability of regulatory requirements prior to use.

This standard is issued under the fixed designation F2271; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A

INTRODUCTION
This standard is intended to outline basic performance requirements for barrel blocking devices. A
barrel blocking device is a critical piece of safety equipment used in the sport of paintball.
Paintball is a sport that, like all sports, has intrinsic hazards. These hazards include being hit by
paintballs. Protective equipment cannot eliminate all injuries but will substantially reduce their
severity and frequency.Abarrel blocking device is an additional safety device that, when meeting this
standard and properly used, can substantially reduce the severity and frequency of injuries. Paintball
marker barrels are not all the same inside diameter, thus necessitating performance specifications for
barrel blocking devices that match the barrel blocking device to a barrel diameter. This specification
is written within the current state-of-the-art of paintball marker barrel and paintball barrel blocking
device technology.The intent is to revise this specification whenever substantive information becomes
available which justifies revising existing requirements or adding new requirements.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
