标准范围

ISO/TR 12391-3适用于所有尺寸（从0.5升到150升）的无缝可再充装钢瓶，钢瓶由抗拉强度大于1100 MPa的钢制成。它也适用于由抗拉强度较低的钢材制成的气瓶。特别是，它提供了技术原理和背景，以指导现有ISO标准的未来更改或开发高级设计标准。ISO/TR 12391-3是有缺陷气缸周期性爆裂试验开发过程中获得的试验结果的总结和汇编。该试验是单调加压条件下缺陷气瓶爆破试验的替代试验方法，用于评估用于运输高压容器的钢瓶的断裂性能-高压压缩气体。在ISO/TR 12391-3中，报告了在抗拉强度范围为750 MPa至1210 MPa的无缝钢瓶上进行的100多个有缺陷钢瓶周期性爆裂试验的试验结果。该试验方法既可用于材料的选择，也可用于在开发新气瓶时确定设计参数，还可用于气瓶生产过程中使用的有效质量控制试验。

ISO/TR 12391-3 applies to seamless refillable cylinders of all sizes from 0,5 l up to and including 150 l water capacity produced of steel with tensile strength greater than 1 100 MPa.It can also be applied to cylinders produced from steels used at lower tensile strengths. In particular, it provides the technical rationale and background to guide future alterations of existing ISO standards or for developing advanced design standards.ISO/TR 12391-3 is a summary and compilation of the test results obtained during the development of the Flawed-cylinder Cyclical-burst Test. The test is an alternate test method to the flawed-cylinder burst test with monotonic pressurization and is used to evaluate the fracture performance of steel cylinders which are used to transport high-pressure compressed gases.In ISO/TR 12391-3 test results are reported for more than one hundred flawed-cylinder cyclical burst tests that were conducted on seamless steel cylinders that ranged in tensile strength from 750 MPa to 1 210 MPa. The test method is intended to be used both for the selection of materials and to establish design parameters in the development of new cylinders as well as for an efficient quality control test to be used during the production of cylinders.
