1、Designation: F1750 16 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, in the case of rev

2、ision, 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 interface a propellant sou

3、rce with a normalworking output pressure of 10 342 kPa (1800 psig) or less to apaintball marker.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, as

4、sociated 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.

The stem of the valve core shall be able to be depressedto a minimum depth of 2.54 mm (0.100 in.) below Datum Bwithout being damaged. If a val

18、ve core is not used there shallnot be any feature of the male connector which will interferewith the valve opening feature of the female fitting.8. Venting8.1 The female connector shall have a provision for the selfventing of residual gas pressure prior to the disconnection ofthe threaded interface.
