1.1 本规程涵盖了使用水作为传热介质的系统上形成的沉积物成分或任何其他用途的水形成沉积物的检查和分析结果的方式，以及如何报告这些结果。 1.2 虽然正在使用各种报告水成沉积物分析的做法，但该做法旨在作为一种合理和全面的做法，以供普遍应用。对于特定行业或个别情况，分子组合可能有用且可取。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 结果用于表征使用水作为传热流体的系统中形成的水垢和水形成的沉积物，或因运输、储存或用于任何其他目的而形成的沉积物。它还用于评估发现沉积物的系统中使用的水质。表征水垢/沉积物将有助于水处理协议的设计，以避免进一步的水垢或沉积物积聚，这可能会由于腐蚀或微生物生长而导致能源消耗增加或系统损坏。 使用现代最新的化学检测系统将提高实践的实用性。

1.1 This practice covers the manner in which the results of examination and analysis for constituents of deposits formed on systems using water as a heat transfer media or water formed deposits from any other purpose and how they are to be reported. 1.2 While various practices of reporting the analysis of water-formed deposits are in use, this practice is intended as a rational and comprehensive practice for general application. For use in specific industries or individual cases, molecular combinations may be useful and desirable. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The results are used to characterize the scale and water formed deposits formed in systems using water as a heat transfer fluid or deposits formed that has resulted from water being transported, stored or used for any other purpose. It is also used to evaluate the quality of water used in the system where the deposit has been found. Characterizing the scale/deposit will assist in the design of the water treatment protocols to avoid further scale or deposit buildups which can cause increased energy consumption or damage to the system due to corrosion or microbiological growth. The use of modern up-to-date chemical detection systems will increase the usefulness of the practice.
