CSA ANSI Z21.41A-2005 pdf download American National Standard/ CSA Standard For Quick Disconnect Devices For Use With Gas Fuel Appliances
1.5.1 A Quick-disconnect device sh II be desiqned o that when disconnected it shall be impossible to Cause gas leakage by manual manip&ation or by the application of simple tools to external surfaces of the device.
1.5.4 The male plug of a ’I8 inch NPT quick disconnect intended for use with a gas convenience outlet, or with a 221 .54 CSA 8.4, Cas Hose Connectors for Portable Outdoor Cas-Fired Appliances, outdoor appliance connector, or with a 221 .69 CSA 6.1 6, Connectors for Movable Cas Appliances, gas connector for movable appliances in residential applications, shall comply with Figure 1, Drawing of the Plug Profile. This does not prohibit the use of other profiles intended for other applications.
1.6 Strength
1.6.1 Quick-disconnect devices shall be capable of supporting the following weights suspended from the extreme outlet end without deformation, breakage or leakage:
Five samples of each style and size of device shall be subjected to the tests specified, four of which shall comply. The inlet ends of completely assembled devices shall be attached to a rigidly supported extra heavy pipe manifold so that they will be horizontal. The weight specified above shall then be suspended from the extreme outlet end of the assembled device without shock. At the end of 1 5 minutes the device shall be subjected to the leakage tests specified in 2.1, Leakage. The weight shall be removed, the device examined for deformation and breakage and again subjected to the leakage test specified in 2.1.
1.6.2 A quick-disconnect device shall be capable of withstanding, without deformation, breakage or leakage, the following turning effort exerted to screw the inlet of the device into a conventional manifold or onto a pipe.
Five samples of each style and size of device shall be subjected to the tests specified below, four of which shall comply. A tool which fits snugly about the body of the device, or to a section of the device shaped for a wrench if such a section is provided, shall be utilized to apply the turning force. The measured torque specified above shall be applied to the device in fitting it into an extra heavy pipe manifold of suitable size or into a suitable pipe fitting. The force shall be applied for 1 5
