[note 1] The international standard for the stamp format is ISO 13769, Gas cylinders - Stamp marking. [1] A hydrostatic test involves pressurising the cylinder to its test pressure (usually 5/3 or 3/2 of the working pressure) and measuring its volume before and after the test.
ISO 11439: Gas cylinders — High-pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles [28] ISO 15500-5: Road vehicles — Compressed natural gas (CNG) fuel system components — Part 5: Manual cylinder valve [29] [30] US DOT CFR Title 49, part 178, Subpart C — Specification for Cylinders [31]
Gas poisonous by inhalation means a material which is a gas at 20 °C or less and a pressure of 101.3 kPa (a material which has a boiling point of 20 °C or less at 101.3kPa (14.7 psi)) and which: Is known to be so toxic to humans as to pose a hazard to health during transportation, or
They are the U.S. counterpart to the UN Regulations developed by the World Forum for Harmonization of Vehicle Regulations and recognized to varying degree by most countries except the United States. Canada has a system of analogous rules called the Canada Motor Vehicle Safety Standards ( CMVSS ), which overlap substantially but not completely ...
CNG must be stored in high-pressure cylinders (21,000 to 25,000 kPa (3,000 to 3,600 psi)), and LNG must be stored in cryogenic cylinders (−162 to −129 °C (−260 to −200 °F)). These cylinders take up more space than gasoline or diesel tanks that can be molded in intricate shapes to store more fuel and use less on-vehicle space.
The 1956 edition of the Texas Official Travel Map: The Transportation Department has been publishing an official state road map since 1917. Every month, TxDOT publishes Texas Highways , a magazine aimed at showcasing various aspects of the state, often by providing interesting travel information on a specific stretch of highway (or highways) in ...
In the twentieth century, the Pipeline and Hazardous Materials Safety Administration (PHMSA), a U.S. Department of Transportation agency, would be established to develop and enforce regulations for the safe and environmentally sound operation of the United States' pipelines, and to collect data on pipeline leaks, accidents, and explosions.

Normal high pressure gas cylinders will hold gas at pressures from 200 to 400 bars (3,000 to 6,000 psi). An ideal gas pressurised to 200 bar in a cylinder would contain 200 times as much as the volume of the cylinder at atmospheric pressure, but real gases will contain less than that by a few percent. At higher pressures, the shortfall is greater.
