Gas cylinders -- Non-refillable metallic gas cylinders -- Specification and test methods
This International Standard specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes and tests at manufacture of non-refillable metallic gas cylinders of welded, brazed or seamless construction for compressed, liquefied and dissolved gases exposed to extreme worldwide ambient temperatures.
This International Standard is applicable to cylinders where:
- the maximum permissible operating pressure does not exceed 250 bar (i.e. pms ≤ 250 bar);
- the product of the maximum permissible operating pressure and the water capacity does not exceed 1000 bar.litres (i.e.pms · V ≤ 1000 bar.l);
- where the maximum permissible operating pressure exceeds 35 bar, the water capacity does not exceed 5 l (i.e. for pms> 35 bar, then V ≤ 5 l).
This International Standard is not applicable to cylinders exceeding these pressure and volume limits, for which reference may be made to refillable cylinder standards.
This International Standard is also not applicable to cartridges/aerosol dispensers1) and spherical containers.
1) Cartridges are non-refillable containers which do not contain an integral dispensing device, have a maximum water capacity of 1 l and have a limited maximum permissible operating pressure (as defined by the country of use). Aerosol dispensers are non-refillable thin-walled containers which do contain an integral dispensing device, have a maximum water capacity of 1 l and have a limited maximum permissible operating pressure (as defined by the country of use).
