CSA 8.5:2018 pdf download.Gas hose connectors for portable and moveable gas appliances
1.1 CSA 8.5 applies to newly produced gas hose connectors for portable and moveable gas appliances constructed entirely of new, unused parts and materials, consisting of flexible tubing for gas leak resistance that:
a) when used indoors, hose connectors are to be equipped with a male plug fitting, which complies with ANSI Z21.90●CSA 6.24, Gas Convenience Outlets and Optional Enclosures;
b) are for use with indoor/outdoor gas-fired appliances;
c) are for use on piping systems having fuel gas pressure not in excess of 5 psi (34.5 kPa);
d) are capable of operation at temperatures between -40°F (-40°C) and 300°F (149°C);
e) are of 1/4 in to 1-1/2 in nominal internal diameters;
f) are of not more than 6 ft (1.83 m) nominal length for indoor use;
g) are of not more than 15 ft (4.57 m) nominal length for outdoor use;
h) are equipped with standard taper pipe threads (conforming to the Standard for Pipe Threads,
General Purpose (Inch), ASME B1.20.1 or the Standard for Dryseal Pipe Threads (Inch), ASME B1.20.3) on the end fittings attaching to the appliance and to the gas supply piping.
Connector, gas appliance一a factory-fabricated assembly of gas conduit and related fittings designed to convey gaseous fuel, and used for connecting the gas supply piping outlet and the gas inlet to an appliance. A connector is equipped at each end for attachment to standard taper pipe threads. A gas appliance connector is not for vibration isolation. Connectors are not designed for repeated movement after being connected or for repeated disconnecting and connecting and are not to be used with quick-disconnect devices. For installation requiring movement of the appliance on a regular basis, refer to ANSI Z21.69●CSA 6.16, Standard for Connectors for Moveable Gas Appliances.
Connector, moveable gas appliance一a connector for use with all castered appliances as well as food service appliances that may, or may not utilize casters and, under conditions of normal use, are moved on a regular basis for service, positioning, or area cleanliness. A connector of this type is not designed for continuous movement and may be equipped with a quick-disconnect device.
Corrugated connector一a metal connector having the gas conduit fabricated of metal tubing formed into helical or annular corrugations.
Connector, gas hose一a connector designed for use only with portable gas-fired equipment. The gas conduit depends for gas tightness on the wall structure of the hose material. The conduit may be supported with internal metal or other reinforcement. The design and application presuppose that the connector will not be pressurized when the appliance served by the connector is not in use. Gas hose connector includes:
