ISO 9809 & 7866: Transporting gas
safely
ISO 9809 and ISO 7866 deal with the design, construction
and testing of steel and aluminium cylinders respectively
for the safe storage and transport of high-pressure
gas. A conservative estimate puts the number of such
cylinders in use around the world at over 130 million.
While these are mainly used in industry, there are other
significant, diverse applications in fields such as
medicine, fire-fighting, emergency operations, sports
and drink-dispensing, all of which bring gas cylinders
close to the public. In most countries, there are national
regulations on gas cylinders, but consolidation within
the compressed gases industry makes the advent of International
Standards opportune. In addition to the technical advantages
of having common standards worldwide, the ISO standards
are influential in the removal of trade obstacles by
providing regulatory bodies with the assurance that
gas cylinders manufactured to ISO standards are safe
and reliable
