Standard Test Method for Sodium Alkylbenzene Sulfonate in Synthetic Detergents by Ultraviolet Absorption 紫外吸收合成洗涤剂中烷基苯磺酸钠的标准试验方法
发布日期: 2024-11-01
1.1 该测试方法涵盖了商业合成洗涤剂和不含有机添加剂如酰胺的洗涤剂配方。通常在配制的洗涤剂中发现的光学染料和材料不会干扰;然而,必须不存在除磺酸盐以外的具有强紫外线吸收的材料。指示的样本量和等分方案基于含有30%至40%活性成分的样品。 1.2 以SI单位表示的值将被视为标准值。本标准不包括其他计量单位。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题(如果有)。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。材料安全数据表可用于试剂和材料。使用前检查它们是否有危险。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。
1.1 This test method covers commercial synthetic detergents and built detergent formulations that do not contain organic additives such as amides. Optical dyes and materials normally found in formulated detergents do not interfere; however, materials other than sulfonates that possess strong ultraviolet absorptions must be absent. The indicated sample size and aliquoting scheme is based on samples containing 30 % to 40 % of active ingredient. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage. 1.4 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.
