DANSK DSF/ISO/FDIS 21053 PDF

This international standard specifies the evaluation method of life cycle analysis of ductile iron pipes used for water applications. Studies on economic and environmental impacts are important for utility decision-makers as they seek to balance fiscal 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 provide the necessary data to support those decisions. Informative Annexes are included in this standard as a compilation of reference and consensual factors (pumping cost, leakage accident rate, etc.) but it is recommended to use local data when they are known and verifiable.
