ASTM F1750-2011(2015) Standard Specification for Paintball Marker Threaded-Propellant Source Interface《彩弹标记物螺纹推进源接口的标准规格》.pdf

1、Designation: F1750 11 (Reapproved 2015) An American National StandardStandard Specification forPaintball Marker Threaded-Propellant Source Interface1This standard is issued under the fixed designation F1750; the number immediately following the designation indicates the year oforiginal adoption or,

2、in the case of revision, 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.1. Scope1.1 This specification covers the male and female threadedconnectors used to interfac

3、e a propellant source with a workingpressure of 10 342 kPa (1800 psig) or less to a paintballmarker.1.2 The values stated in SI units are to be regarded asstandard. The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety concerns, if any

4、, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
