b) Refrigerants,

c) Gasoline or gasohol formulated in accordance with Standard Specification for Automotive Spark- Ignition Engine Fuel, ANSI/ASTM D 4814,

d) Diesel fuel formulated in accordance with Standard Specification for Diesel Fuel Oils, ANSI/ASTM D 975,

e) Heating fuel oils formulated in accordance with Standard Specification for Fuel Oils, ANSI/ASTM D 396, and

f) Kerosene formulated in accordance with Specification for Kerosine, ANSI/ASTM D 3699.

The requirements for "Marine Use" cover fittings to be used with tubing carrying gasoline or gasohol formulated in accordance with Standard Specification for Automotive Spark-Ignition Engine Fuel, ANSI/ASTM D 4814, or diesel fuel formulated in accordance with Standard Specification for Diesel Fuel Oils, ANSI/ASTM D 975.

This standard does not cover tube fittings for liquid or gaseous Biofuels or Ethanol fuels other than gasohol noted in 1.1 (c) and 1.2.

Requirements for the selection, installation, and use of the fittings covered by this Standard are included in the Standards of the National Fire Protection Association pertaining to storage and use of flammable and combustible fluids, such as:
