标准摘要
[中文适用范围]： 本文件规定了 ISO 2531 和 ISO 16631 中规定的用于水应用的球墨铸铁管生命周期分析的评估方法。 经济和环境影响的研究对于公用事业决策者来说非常重要，因为他们寻求平衡预算问题采购、运营和维护以及计划寿命终止的长期需求。 对于设计管道系统的当局和工程师来说，生命周期成本分析可以作为研究各种场景的工具，以确定适合现场特定条件和社区价值的正确解决方案，并提供必要的数据来支持这些决策。 本文件中包含资料性附件，作为参考因素和共识因素（泵送成本、泄漏事故率等）的汇编。 [外文原描述]： This document specifies the evaluation method of life cycle analysis of ductile iron pipes used for water applications as specified in ISO 2531 and ISO 16631. Studies on economic and environmental impacts are important for utility decision-makers as they seek to balance budget concerns over immediate and long-term needs across acquisition, operations and maintenance, and planned end of life. For authorities and engineers designing pipeline systems, the life cycle cost analysis serves as a tool to study various scenarios to determine the right solution for site-specific conditions and community values, as well as to provide the necessary data to support those decisions. Informative annexes are included in this document as a compilation of reference and consensual factors (pumping cost, leakage incident rate, etc.).
