scope:

These requirements cover pigtails and flexible hose connectors used in the assembly of fuel-supply systems other than those outlined in 1.3(b) and (c), intended for liquefied petroleum gas (LP-Gas). Low or high pressure flexible hose connectors are also suitable for low pressure (1.0 psig (6.9 kPa) or less) natural gas service. LP-Gas systems use either Department of Transportation (DOT) cylinders or ASME tanks and are intended to be installed in accordance with the Liquified Petroleum Gas Code, NFPA/ANSI 58. Low pressure flexible hose connectors used in natural gas systems are intended to be installed in accordance with the National Fuel Gas Code, NFPA 54/ANSI Z223.1. Pigtails and flexible hose connectors are used to make connection between parts of equipment or between equipment and service piping.

These requirements also cover hose without end-connection fittings that is used to manufacture flexible hose connectors.

This Standard does not apply to:

a) Gas appliance connectors for handling fuel gases at 5 psig (34.5 kPa) or less which are investigated under the Standard for Metal Connectors for Gas Appliances, ANSI Z21.24.

b) Flexible hose connectors for engine fuel applications which are investigated under the Outline of Investigation, LP-Gas Fuel Hose and Hose Assemblies for Vehicle Engines, UL 1785.

c) Flexible hose connectors for use in confined areas.

d) Hose connectors which are investigated under the Standard for Gas Hose Connectors for Portable Outdoor Gas-Fired Appliances, ANSI Z21.54.
