This part of ISO\/TR 12391 applies to seamless steel refillable cylinders of all sizes from 0,5 l up to and including<\/p>\n

150 l water capacity produced of steel with tensile strength, R<\/i>m, greater than 1 100 MPa.<\/p>\n

It can also be applied to cylinders produced from steels used at lower tensile strengths. In particular, it provides<\/p>\n

the technical rationale and background to guide future alterations of existing ISO standards or for developing<\/p>\n

advanced design standards.<\/p>\n

This part of ISO\/TR 12391 is a summary and compilation of the test results obtained during the development<\/p>\n

of the "flawed-cylinder cycle test". The "flawed-cylinder cycle test" was developed as part of a co-operative<\/p>\n

project under the direction of ISO\/TC 58\/SC 3\/WG 14. The "flawed-cylinder cycle test" is a test method to<\/p>\n

evaluate the fatigue performance of steel cylinders that are used to transport high pressure, compressed<\/p>\n

gases.<\/p>\n

The concept and development of the flawed-cylinder cycle test is described in ISO\/TR 12391-1. The details of<\/p>\n

the test method and the criteria for acceptable fatigue performance of steel cylinders are given in 9.2.6 of<\/p>\n

ISO 9809-2:2000, "flawed-cylinder cycle test". In this part of ISO\/TR 12391, test results are reported for more<\/p>\n

than a hundred flawed-cylinder cycle tests that were conducted on seamless steel cylinders ranging in<\/p>\n

measured tensile strength from less than 800 MPa to greater than 1 350 MPa. The test method is intended to<\/p>\n

be used for the selection of materials and design parameters in the development of new cylinder designs.<\/p>\n","protected":false},"excerpt":{"rendered":"
