Water meters for cold potable water and hot water - Part 3: Test report format (ISO 4064-3:2024)

This specification outlines the required structure and content for generating test reports related to water meters used for measuring cold water and hot water consumption. It defines the specific layout, data elements, and presentation formats that must be included in documentation produced during the evaluation and verification processes of these measuring instruments. The document serves as a standardized template to ensure consistency, clarity, and completeness across all test reports generated for meters falling within the scope of the broader metrological framework. By adhering to these guidelines, manufacturers and testing laboratories can produce uniform reports that facilitate comparison and regulatory review. The content covers essential details regarding the testing conditions, the results obtained, the equipment utilized, and the final determination of conformity or non-conformity. This approach supports international harmonization by aligning national documentation requirements with established global practices for water meter metrology, ensuring that technical data is communicated effectively to stakeholders involved in water supply management and legal metrology.
