ISO/TR 12391的这一部分是对开发过程中获得的测试结果的总结和汇编 “有缺陷的汽缸爆裂试验”的一部分。介绍了有缺陷气缸爆裂试验的概念和发展 如ISO/TR 12391-1所述。该试验是评估钢瓶断裂性能的一种方法 用于输送高压压缩气体的。在ISO/TR 12391的本部分中，试验结果如下: 报告了在无缝钢瓶上进行的数百次有缺陷的钢瓶爆裂试验 拉伸强度范围从小于750 MPa到约1400 MPa。 该试验方法已被证明能可靠地预测无缝钢瓶的断裂性能。这个 本试验方法既可用于材料的选择，也可用于设计参数的选择 开发新的气缸设计，并在测试期间进行有效的质量控制测试 气瓶的生产。

This part of ISO/TR 12391 is a summary and compilation of the test results obtained during the development of the "Flawed-Cylinder Burst Test". The concept and development of the flawed cylinder burst test is described in ISO/TR 12391-1. The test is a method for evaluating the fracture performance of steel cylinders that are used to transport high pressure, compressed gases. In this part of ISO/TR 12391, test results are reported for several hundred flawed cylinder burst tests that were conducted on seamless steel cylinders ranging in tensile strength from less than 750 MPa up to about 1 400 MPa. This test method has been shown to reliably predict the fracture performance of seamless steel cylinders. The test method is intended to be used both for the selection of materials and design parameters in the development of new cylinder designs as well as for an efficient quality control test to be used during the production of cylinders.
