1、Designation: F 1750 05An American National StandardStandard Specification forPaintball Marker Threaded-Propellant Source Interface1This standard is issued under the fixed designation F 1750; the number immediately following the designation indicates the year oforiginal adoption or, in the case of re
2、vision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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 s
3、ource 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, associated wit
4、h 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.

6、5 O-Ring Dash Sizes3. Connector Gender Assignment3.1 The female connector is that connector which is config-ured as part of the paintball marker.3.2 The male connector is that connector which is config-ured as part of the propellant source.4. Materials and Manufacture4.1 The male and female connecto
7、rs shall be made frommaterials that are compatible with CO2. The materials andprocesses used to manufacture male and female connectorsshall result in items with mechanical strength sufficient to passa 20 684-kPa (3000-psig) proof pressure check without failureor any degradation to function.4.2 The O
8、-ring seal shall be made from an elastomercompatible with CO2. The O-ring seal shall have a hardnessthat will register a Type A durometer reading of 90 6 5. TheO-ring shall conform dimensionally to MS28775-015 andconform to Test Method D 2240.4.3 The O-ring seal shall be installed on the male connec
9、torin the groove described by Dimensions C and K on Fig. 1.4.4 The male and female connectors shall not have anysharp edges or hanging burrs. All sharp edges will be brokenR.38 MAX (R.015 MAX).5. Performance5.1 The interface is intended for use with CO2compressedair or gaseous CO2, or both.5.2 The m
10、aximum operating pressure of the interface is10 342 kPa (1800 psig).5.3 The maximum allowable leakage at 10 342 kPa (1800psig) is 0.1 cm3/min.5.4 The male connector shall incorporate a means forpropellant shutoff that shall meet the maximum leakage re-quirement.5.5 When the male and female connector
11、s are joined andpressurized, together they shall meet the maximum leakagespecification.6. Physical Envelope6.1 The male connector shall conform to the physicalenvelope described in Fig. 1.1This specification is under the jurisdiction of ASTM Committee F08 on SportsEquipment and Facilities and is the

Full flow must beachieved when the stem of the valve core has been depressed1.78 mm (0.070 in.) from the surface designated as Datum B inFig. 1. The stem of the valve core shall be able to
17、 be depressedto a minimum depth of 2.54 mm (0.100 in.) below Datum Bwithout being damaged. If a valve 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 provisio
18、n for the selfventing of residual gas pressure prior to the disconnection ofthe threaded interface. Fig. 2 (Dimensions D and H) shows arecommended location and feature size for a vent hole.9. Operating Temperatures9.1 The interface shall have an operating range from 40to + 54C (40 to + 130F).10. Flo
19、w10.1 The interface shall flow not less than 170 sL/min at 689kPa (6 S.C.F.M. at 100 psid).10.2 The feature allowing flow through the female connec-tor shall lie within the area designated by minimum DimensionMinFig. 2.10.3 The feature allowing flow through the male connectorshall lie within the are
