CEN/TC 23/SC 3 - Operational requirements

ISO 10462 specifies requirements for the periodic inspection of acetylene cylinders as required for the transport of dangerous goods and for maintenance in connection with periodic inspection. It applies to acetylene cylinders with and without solvent and with a maximum nominal water capacity of 150 l.

ISO 10462:2013 specifies requirements for the periodic inspection of acetylene cylinders as required for the transport of dangerous goods and for maintenance in connection with periodic inspection. It applies to acetylene cylinders with and without solvent and with a maximum nominal water capacity of 150 l.

ISO 3807:2013 specifies the basic and type testing requirements for acetylene
cylinders with and without fusible plugs with a maximum nominal water capacity
of 150 l and requirements regarding production/batch test procedures for
manufacturing of acetylene cylinders with porous material.
It does not include details of the design of the cylinder shell; these are
specified, for example, in ISO 9809 1, ISO 9809 3, ISO 4706 and ISO
7866.

This European Standard deals with welded steel transportable pressure drums intended for compressed and liquefied gases under pressure of water capacity from 150 litres up to 1 000 litres.
This European Standard specifies the requirements for periodic inspection and testing to verify the integrity of such pressure drums to be re-introduced into service for a further period of time. It also defines a procedure to qualify existing pressure drums for free movement between member states of the European Union (see Annex A).

ISO 10961:2010 specifies the requirements for the design, construction, testing and initial inspection of a transportable cylinder bundle. It is applicable to cylinder bundles containing compressed gas, liquefied gas and mixtures thereof. It is also applicable to cylinder bundles for acetylene.
It does not apply to packages in which cylinders are manifolded together in a support frame which is designed to be fixed permanently to a road vehicle, to a railway wagon or to the ground as a customer storage vessel. It does not apply to cylinder bundles which are designed for use in extreme environmental or operational conditions when additional and extraordinary requirements are imposed to maintain safety standards, reliability and performance, e.g. offshore cylinder bundles.
Specific requirements for acetylene cylinder bundles containing acetylene in a solvent are included in an annex. ISO 10961 does not, however, cover acetylene cylinder bundles with solvent-free acetylene cylinders.
ISO 10961 is intended primarily for industrial gases other than liquefied petroleum gases (LPGs), but it may also be used for LPGs.

ISO 16148:2006 is a guideline for using acoustic emission testing (AT) during re-qualification of seamless steel cylinders and tubes of water capacity up to 3 000 l used for compressed and liquefied gases. For cylinders below 20 l additional precautions may be taken due to the potential reflections from the ends. This test provides indications and locations that should be evaluated by another test for a possible flaw in the cylinder. ISO 16148:2006 covers monolithic steel cylinders.

This European Standard specifies the basic requirements for acetylene cylinders with a maximum nominal water capacity of 150 l, including:
-   the procedure for type testing;
-   the procedure for production/batch testing;
-   the methods for determining the maximum permissible settled pressure;
-   the method for determining the porosity of the porous material;
It does not include details of designs for the cylinder shell.
