标准范围

ISO/TR 12391的这一部分适用于0.5升至0.5升（含0.5升）的所有尺寸的无缝钢制可再充装钢瓶150升水容量，由抗拉强度Rm大于1 100 MPa的钢制成。它也可以应用于由抗拉强度较低的钢生产的圆柱体。特别是，它提供了指导现有ISO标准未来变更或开发的技术原理和背景先进的设计标准。ISO/TR 12391的这一部分是开发过程中获得的测试结果的总结和汇编“缺陷气缸循环试验”。“缺陷气缸循环测试”是作为合作项目的一部分开发的ISO/TC 58/SC 3/WG 14指导下的项目。“缺陷气缸循环试验”是一种试验方法评估用于运输高压、压缩的钢瓶的疲劳性能气体。ISO/TR 12391-1中描述了缺陷气缸循环试验的概念和发展。的详情钢圆筒疲劳性能可接受的试验方法和准则见第9.2.6条。ISO 9809-2:20 00，“有缺陷的气缸循环试验”。在ISO/TR 12391的这一部分中，报告了更多的测试结果对无缝钢气缸进行了一百多次有缺陷的气缸循环试验，范围为测量的拉伸强度从小于800 MPa到大于1 350 MPa。本试验方法旨在用于新气缸设计开发中材料和设计参数的选择。

This part of ISO/TR 12391 applies to seamless steel refillable cylinders of all sizes from 0,5 l up to and including150 l water capacity produced of steel with tensile strength, Rm, greater than 1 100 MPa.It can also be applied to cylinders produced from steels used at lower tensile strengths. In particular, it providesthe technical rationale and background to guide future alterations of existing ISO standards or for developingadvanced design standards.This part of ISO/TR 12391 is a summary and compilation of the test results obtained during the developmentof the "flawed-cylinder cycle test". The "flawed-cylinder cycle test" was developed as part of a co-operativeproject under the direction of ISO/TC 58/SC 3/WG 14. The "flawed-cylinder cycle test" is a test method toevaluate the fatigue performance of steel cylinders that are used to transport high pressure, compressedgases.The concept and development of the flawed-cylinder cycle test is described in ISO/TR 12391-1. The details ofthe test method and the criteria for acceptable fatigue performance of steel cylinders are given in 9.2.6 ofISO 9809-2:2000, "flawed-cylinder cycle test". In this part of ISO/TR 12391, test results are reported for morethan a hundred flawed-cylinder cycle tests that were conducted on seamless steel cylinders ranging inmeasured tensile strength from less than 800 MPa to greater than 1 350 MPa. The test method is intended tobe used for the selection of materials and design parameters in the development of new cylinder designs.
