Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The following definitions shall apply in the application
						and interpretation of these Orders.
For definitions directly relevant to LP-Gas, see 1998
						Edition of NFPA 58, Section
						1-6.
49 CFR: Title 49, Code of Federal Regulations, Parts
						100-199.
Acceptable: Capable of performing the particular function
						specified in the Order with safety.
Air Brake Tank: An air tank 10 inches or less in
						diameter, having a capacity of 1 ½ cubic feet or less, and operating at
						150 psig or less, and used exclusively to supply air to the braking systems of
						automotive vehicles and other air-operated auxiliaries used in the operation of
						such vehicles. The 150 psig limitation need not apply to tanks less than 6
						inches in inside diameter.
Air Tank: A pressure vessel used for the storage or
						accumulation of air under pressure. This definition is not intended to include
						utilization equipment, including such devices as grease tanks, fire
						extinguishers, paint sprayers, etc., where the tank is partly filled with a
						product and the air pressure is used only for a cushion or to eject the product
						from the tank, or such devices as strainers, scrubbers, separators, etc., that
						are a part of the piping system.
Alteration: A change in any item described on the
						original Manufacturer's Data Report which affects the pressure capability of
						the pressure vessel.
ANSI Standards: Standards approved by the American
						National Standards Institute, Inc.
(A)
					 Chemical Plant and Petroleum Refinery Piping, ANSI B31.3 (except non-metallic
					 pipe such as plastic is not acceptable unless permitted by specific safety
					 orders).
(B) Refrigeration Piping,
					 ANSI B31.5.
Applicator Tank: A service tank used in agriculture for
						applying anhydrous ammonia to the soil, or for other agricultural uses.
Approved: See Section
						3206, General Industry Safety
						Order.
Appurtenance: A device installed on and used in the
						normal operation of the vessel. This includes, but is not limited to, safety
						relief devices, liquid level gauging devices, valves, and pressure
						gauges.
Artificial Heat: Any heat other than solar or atmospheric
						heat.
ASME Code: The American Society of Mechanical Engineers'
						Boiler and Pressure Vessel Code.
