CSA 8.4:19 Gas hose connectors for portable outdoor gas-fired appliances.
The following definitions shall apply in this Standard:
Adaptor a metal fitting designed to connect standard taper pipe threads to the connector nut. Appliance — all gas utilization equipment.
Capacity — the amount of a specified gas that will flow through a connector at a specified pressure drop in a fixed period of time.
Conduit, gas — the gas passageway of the connector.
Connecter, gas appliance — a factory-fabricated assembly of gas conduit and related fittings designed to convey gaseous fuel, and used for making connections between a gas supply piping outlet and the gas inlet to an appliance. It is equipped at each end for attachment to standard taper pipe threads. A gas appliance connector is not for vibration isolation.
Connector, movable gas appliance — a connector for use with appliances (including all commercial cooking appliances) that may or may not be equipped with castors and that under conditions of normal use, are moved on a regular basis. A connector of this type Is for occasional but not continuous movement. Connectors of this type may be used with quick disconnect devices.
Metal connector — a connector with a gas conduit made entirely of metal. It is not designed for repeated movement after being connected nor for repeated disconnecting and connecting.
Corrugated connector — a metal connector having the gas conduit fabricated of metal tubing formed into helical or annular corrugations.
Semi-rigid connector — a metal connector having the gas conduit fabricated of semi-rigid metal.
Other than all-metal connector — a connector having metal fittings, but with the gas conduit being of a non-metallic material. The gas conduit is protected by a metal sheath. It is not designed for repeated movement after being connected nor for repeated disconnecting and reconnecting.
Connector, gas hose — 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:
Gas hose connector for portable indoor gas-fired equipment — a gas hose connector for use only with laboratory, shop or ironing equipment used indoors that requires mobility during operation.CSA 8.4 pdf download.
