| Nosaukums | <p>This part of ISO/TR 12391 applies to seamless steel refillable cylinders of all sizes from 0,5 l up to and including</p> <p>150 l water capacity produced of steel with tensile strength, <i>R</i>m, greater than 1 100 MPa.</p> <p>It can also be applied to cylinders produced from steels used at lower tensile strengths. In particular, it provides</p> <p>the technical rationale and background to guide future alterations of existing ISO standards or for developing</p> <p>advanced design standards.</p> <p>This part of ISO/TR 12391 is a summary and compilation of the test results obtained during the development</p> <p>of the "flawed-cylinder cycle test". The "flawed-cylinder cycle test" was developed as part of a co-operative</p> <p>project under the direction of ISO/TC 58/SC 3/WG 14. The "flawed-cylinder cycle test" is a test method to</p> <p>evaluate the fatigue performance of steel cylinders that are used to transport high pressure, compressed</p> <p>gases.</p> <p>The concept and development of the flawed-cylinder cycle test is described in ISO/TR 12391-1. The details of</p> <p>the test method and the criteria for acceptable fatigue performance of steel cylinders are given in 9.2.6 of</p> <p>ISO 9809-2:2000, "flawed-cylinder cycle test". In this part of ISO/TR 12391, test results are reported for more</p> <p>than a hundred flawed-cylinder cycle tests that were conducted on seamless steel cylinders ranging in</p> <p>measured tensile strength from less than 800 MPa to greater than 1 350 MPa. The test method is intended to</p> <p>be used for the selection of materials and design parameters in the development of new cylinder designs.</p> |
