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 sitespecific conditions and community values, as well as to provide the necessary data to support those decisions.Cross References:ISO 2531EN 15804ISO 15686-5ISO 16631CEN/TR 16470ISO 21930All current amendments available at time of purchase are included with the purchase of this document.
