1.1 This guide covers the considerations for advanced oxidation processes (AOPs) in the mitigation of spilled chemicals and hydrocarbons dissolved into ground and surface waters. 1.2 This guide addresses the application of advanced oxidation alone or in conjunction with other technologies. 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.In addition, it is the responsibility of the user to ensure that such activity takes place under the control and direction of a qualified person with full knowledge of any potential safety and health protocols. 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.

本标准在原“碱性钠型”基础上，将产品细分成了碱性“钠稳定剂型”、“钾稳定剂型”、“铵稳定剂型”三大类，且在“钠稳定剂型”中，又根据含量和粒径大小不同，细分出了19个型号，并增加了“中性”产品类别。在氧化钠含量、pH值、黏度三项指标中，增加了硅粉法的适用指标要求。增补了 “碱性钾型”、“碱性铵型”、“中性”、“大粒径”硅溶胶产品的理化指标范围规定。并将大粒径硅溶胶的粒径范围进行了分段，以提升精准程度。
