ISO 16708:2006规定了使用ISO 13623允许的基于可靠性的极限状态方法对石油和天然气行业的管道进行设计、运行和重新鉴定的功能要求和原则。基于可靠性的极限状态方法为管道设计和运行中的安全预测提供了一种系统的方法。ISO 16708:2006是对ISO 13623的补充，可用于ISO 13623未提供具体指导的情况，以及可应用极限状态方法的情况，例如但不限于:-新概念的鉴定，例如，当应用新技术或行业经验有限的设计方案时，-由于设计基础的改变，如使用寿命的延长，对管道进行重新鉴定，这可能包括由于完整性监测和运行经验的改善而减少的不确定性，-在外部压力下在深水中坍塌，-极端荷载，如地震荷载（如断层交叉处）、冰荷载（如冰龙骨的冲击），-基于应变的标准可能适用的情况。ISO 16708:2006适用于石油和天然气工业中使用的陆地和海上刚性金属管道。

ISO 16708:2006 specifies the functional requirements and principles for design, operation and re-qualification of pipelines in the petroleum and natural gas industries using reliability based limit state methods as permitted by ISO 13623. Reliability-based limit state methods provide a systematic way to predict pipeline safety in design and operation.ISO 16708:2006 supplements ISO 13623 and can be used in cases where ISO 13623 does not provide specific guidance and where limit states methods can be applied, such as, but not limited to- qualification of new concepts, e.g. when new technology is applied or for design scenarios where industry experience is limited,- re-qualification of the pipeline due to a changed design basis, such as service-life extension, which can include reduced uncertainties due to improved integrity monitoring and operational experience,- collapse under external pressure in deep water,- extreme loads, such as seismic loads (e.g. at a fault crossing), ice loads (e.g. by impact from ice keels),- situations where strain-based criteria can be appropriate.ISO 16708:2006 applies to rigid metallic pipelines on-land and offshore used in the petroleum and natural gas industries.
