CSA ANSI Z21.75-2016 Connectors for outdoor gas appliances and manufactured homes.
3 Definitions
The following definitions shall apply in this Standard:
Adapter — as used in this Standard, a metal fitting designed to connect standard taper pipe threads to the connector nut.
Appliance — all gas utilization equipment.
Capacity — as used in this Standard, 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 structure enclosing the gas passageway of the connector.
Connector, 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 or a manufactured (mobile) home. It is equipped at each end for attachment to standard taper pipe threads. A gas appliance connector is not for vibration isolation. Connectors for gas appliances, Z21.24 • CSA 6.10, are not designed for repeated movement after being connected or for repeated disconnecting and connecting. For installation requiring movement of the appliance on a regular basis, refer to ANSI Z21.19 • CSA 6.16, Connectors for moveable gas appliances.
Connector for stationary appliance for outdoor installation — a connector for use between the gas supply and the gas inlet of a stationary appliance installed outdoors.
Connector, moveable gas appliance — 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.
Connector nut — a threaded nut permanently attached to a connector conduit which mates with an adapter or manual valve to form a union joint.
Gas hose connector — a connector designed for use only with portable gas-burning equipment. The gas conduit depends for gastightness 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 outdoor gas-fired appliance — a gas hose connector for use with portable gas-burning equipment used outdoors.
Gas valve — a manually operated valve that permits control of the flow of gas at any rate from none to “full on.”
Listed — equipment or materials included in a list published by a nationally recognized testing laboratory, inspection agency, or other organization concerned with product evaluation that maintains periodic inspection of production of listed equipment or materials and whose listing states either that the equipment or material meets nationally recognized standards or has been tested and found suitable for use in a specified manner.
Propane a liquefied petroleum gas that is classified as either “commercial propane” or “Special-Duty” propane in accordance with ASTM 01835, Standard Specification for Liquefied Petroleum (LP) Gases. Special-Duty propane is equivalent to Propane HD-5.
Propane HD-5 — propane that complies with the same requirements as “Special-Duty” propane, as defined in ASTM 01835, Standard Specification for Liquefied Petroleum (LP) Gases.
Protective coating — as used in this Standard, material applied to the exterior surface of the connector to enhance resistance to corrosive materials.
Tubing — as used in this Standard, the material from which the gas conduit of a connector is fabricated.
Union — an assembly of parts to facilitate connection or disconnection between the connector and gas piping without rotation of the connector tubing.
Union, ground joint — a union consisting of three parts (nut, swivel, and end piece) concentrically machined to provide alignment.CSA ANSI Z21.75 pdf download.
