					 shall mean the temperature at which the liquid gives off vapor sufficient to
					 form an ignitable mixture with the air near the surface of the liquid or within
					 the vessel used as determined by the following tests procedure and
					 apparatus:
(i) The flash point of
				  liquids having a flash point at or below 175°F, except for fuel oils and
				  certain viscous materials, shall be determined in accordance with the standard
				  method of test for flash point by the Tag closed tester.
(ii) The flash point of liquids having a
				  flash point above 175°F, except for fuel oils, shall be determined in
				  accordance with the standard method of test for flash point by the Cleveland
				  open cup tester.
(iii) The flash
				  point of fuel oil, and certain viscous materials having a flash point at or
				  below 175°F, shall be determined in accordance with the standard method of
				  test for flash point by the Pensky-Martens closed tester.
GPM
-Gallons per minute.
Inflammable
-Flammable.
Liquid
-When not otherwise identified, both
					 flammable and combustible liquids.
Listed
-Devices and materials that have
					 been investigated by and meet the listing requirements of a nationally
					 recognized testing agency. The equipment shall be identifiable by means of a
					 label or other distinguishing marking specified in listings published by the
					 testing agency.
