1 Scope

1.1 This Standard sets forth minimum requirements for emergency breakaway fittings, swivel connectors and pipe-connecting fittings of the threadless compression type. Connectors and fittings covered by these requirements are intended only for the following services.

1.2 A swivel connector is either a hose swivel or swivel joint. The swivel connector will allow radial movement and is constructed for petroleum product, liquefied petroleum gas (LP-Gas) or anhydrous ammonia (NH₃) service.

NOTE: For the purposes of this standard the terms “LP-Gas” and “Propane” are interchangeable.

1.3 An emergency breakaway fitting is used between the outlet of the dispensing device and the hose nozzle valve or lever-operated fuel transfer valve (LP-Gas Service) and separates in the event that the coupling is subjected to an excessive pull force to safeguard against abnormally excessive pull force on the hose assembly and dispenser and to prevent loss of liquid. An emergency breakaway fitting is constructed for petroleum product, liquefied petroleum gas (LP-Gas) or anhydrous ammonia (NH3) service. The fittings are single-break fittings or reconnectable fittings.

1.4 Products covered by this Standard are intended to be installed and used in accordance with the applicable Codes and Regulations as determined by the Authority Having Jurisdiction (AHJ), such as, but not limited to:

1. a) In the United States:

   1. 1) Flammable and Combustible Liquids Code, NFPA 30;

   2. 2) Code for Motor Fuel Dispensing Facilities and Garages, NFPA 30A;

   3. 3) Liquefied Petroleum Gas Code, NFPA 58; and or

   4. 4) Safety Requirements for the Storage and Handling of Anhydrous Ammonia, ANSI/CGA G-2.1 (ANSI K61.1)

2. b) In Canada:

   1. 1) The National Fire Code of Canada; and or

   2. 2) Provincial or other Regulations.
