13、 a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represen
14、ted on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are dr
15、afted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International S
16、tandard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

19、he cylinders can be reintroduced into service for a further period of time. The original periodic inspection and test procedures for transportable refillable welded steel LPG cylinders were based on those for gas cylinders or other pressure vessels, including those used for high-pressure industrial
20、gases. These early methods relied on a periodic hydraulic proof pressure test being carried out at intervals as frequently as two years (pre-1940). With increasing experience and confidence so gained, together with improved cylinder manufacturing quality, it has been possible to allow the extension
21、of the intervals between periodic tests to 15 years. Periodic inspection is normally carried out at a test station operating under the supervision of a competent body. This International Standard has been prepared to reflect the current state of the art for the periodic inspection of LPG cylinders a
22、nd is based on the operating experience of millions of cylinders in service over many years.

25、lth if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. It has been assumed in the drafting of this International Standard that the execution of its provisions is entrusted to
26、appropriately qualified and experienced people. 1Scope This International Standard specifies the intervals and inspection and testing procedures for the periodic inspection of refillable welded steel dedicated LPG cylinders of water capacity from up to and including . It applies to cylinders protect
27、ed by a system to prevent external corrosion and designed and manufactured in accordance with ISO 4706, ISO 22991 or an equivalent design and construction standard. This International Standard may also apply to other refillable welded steel cylinder designs for LPG with the approval of the national
28、authority. Cylinders for the on-board storage of LPG as a fuel for vehicles are excluded from this standard, except cylinders used for fork-lift truck applications. 2Normative references The following referenced documents are indispensable for the application of this document.
