ISO 19448:2018规定了牙科产品（包括牙膏、凝胶、漱口液、氟化物释放清漆和其他含氟产品）中氟化物浓度量化的试验方法。这些方法基于氟离子选择电极技术，用于分析来自牙科产品的水样本中的氟化物。

ISO 19448:2018 specifies test methods for the quantification of fluoride concentrations in dental products including dentifrices, gels, oral rinses, fluoride releasing varnishes, and other fluoride containing products. The methods are based on fluoride ion-selective electrode technology for the analysis of fluoride in aqueous samples derived from dental products.
