摘要

ISO 11114-4:2005 specifies test methods and the evaluation of results from these tests in order to qualify steels suitable for use in the manufacture of gas cylinders (up to 3 000 l) for hydrogen and other embrittling gases.ISO 11114-4:2005 only applies to seamless steel gas cylinders.The requirements of ISO 11114-4:2005 are not applicable if at least one of the following conditions for the intended gas service is fulfilled:the working pressure of the filled embrittling gas is less than 20 % of the test pressure of the cylinder;the partial pressure of the filled embrittling gas of a gas mixture is less than 5 MPa (50 bar) in the case of hydrogen and other embrittling gases, with the exception of hydrogen sulphide and methyl mercaptan in which cases the partial pressure shall not exceed 0,25 MPa (2,5 bar). ISO 11114-4:2005规定了这些测试的测试方法和结果的评估，以便适合用于制造气瓶（最高达3000升）的钢用于氢气和其他脆化气体。ISO 11114-4:2005仅适用于无缝钢气瓶。如果满足预期燃气服务的以下条件中的至少一个，则ISO 11114-4:2005的要求不适用:填充的脆化气体的工作压力小于气缸试验压力的20％;在氢气和其他脆化气体的情况下，气体混合物的填充的脆化气体的分压小于5MPa（50巴），除了硫化氢和甲基硫醇之外，其中分压不应超过0，25MPa（2.5巴）展开▼
