13、eproduction or networking permitted without license from IHS -,-,- o IS0 ISO/TR 13763:1994(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carrie
14、d out through IS0 technical committees. Each inember body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. I
15、S0 collaborates closely with the International Electrotechnical Commission (EC) on all matters of electrotechnical standardization. The main task of technical committees is to prepare International Standards, but in exceptional circumstances a technical committee may propose the publication of a Tec
16、hnical Report of one of the following types: - type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; - type 2, when the subject is still under technical development or where for any other reason there is the future but not im
17、mediate possibility of an agreement on an Intemational Standard; - type 3, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art“, for example). Technical Reports of types 1 and 2 are subject to review
18、within three years of publication, to decide whether they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful. I S O m 13763, which is a Technical Report of type
19、 3, was prepared by Technical Committee ISORC 58, Gas cylirzders, Subcommittee SC 3, Cylinder design. . 111 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Rock Island Arsenal/9983967100, User=Schabilion, Shelley Not for Resale, 04/10/2007 06:

21、d experience in several IS0 member countries. Revisions to these standards should take into account developments in gas cylinder technology so that cylinders may employ different metallic materials, design criteria and methods of test appropriate to the higher stresses and the environmental conditio
22、ns they may encounter in service. iv Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Rock Island Arsenal/9983967100, User=Schabilion, Shelley Not for Resale, 04/10/2007 06:38:22 MDTNo reproduction or networking permitted without license from I

29、 minimum bursting pressure to the test pressure. 3.3 total safety factor: The product of the application safety factor and the burst safety factor (i.e. the ratio of the minimum bursting pressure to the maximum developed pressure). 3.4 yield factor (design safety factor): The ratio of the pressure a

(variable): The ratio of equivalent wall stress at test pressure to guaranteed minimum yield stress b) it is manufactured by a different process; c) it is manufactured fiom a material of different nominal chemical
31、 composition; d) it is given a different heat treatment; e) the base profile and base thickness have changed relative to the cylinder diameter and calculated minimum wall thickness; f) the guaranteed minimum yield stress has changed by more than 50 N/mm2; g) the length of the cylinder has increased
32、by more than 50 % , NOTE - Cylinders with an UD ratio less than 3 shall not be used as reference cylinders for any new design with an UD ratio greater than 3. h) the diameter has changed by more than 5 % ; j ) an increase in hydraulic test pressure requires a change in design wall thickness. NOTE -
33、Where a cylinder is to be used at a lower pressure duty than that for which design approval has been given, it shall not be deemed to be of a new design. 3 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Rock Island Arsenal/9983967100, User=Sc
