摘要
Abstract
In order to improve the accuracy of the determination results of total active matter content in hand dishwashing detergent,it is necessa-ry to analyze the influencing factors and evaluate the uncertainty of the determination results.According to the test method A in"Test Method for Surfactant Detergent"(GB/T13173-2021),the standard uncertainty is introduced from the repeatability of measurement results;The standard uncertainty introduced in sample mass weighing;The standard uncertainty introduced in the mass weighing of ethanol extract;The standard un-certainty of the introduction of silver nitrate standard solution concentration;The standard uncertainty introduced into the burette titration volume was evaluated reasonably.And the synthetic standard uncertainty and extended uncertainty were calculated at last,multiplied by the expansion factor k=2 under 95%confidence probability to obtain the relative extended uncertainty of the measured results and the reported results.关键词
