本文件规定了一种对强迫选择感官辨别测试数据进行统计分析的程序，例如三角形、duo-trio、3-AFC、2-AFC，在该程序中，每次尝试辨别测试后，可以决定停止测试并宣布差异，停止测试并宣布无差异，或继续测试。 与使用预定数量评估的传统方法相比，序贯方法通常允许在更少的歧视测试试验后做出决定。交叉引用:ISO 5492ISO 5495ISO 6658ISO 10399ISO 8586ISO 4120ISO 3534-1购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document specifies a procedure for statistically analysing data from forced-choice sensory discrimination tests, such as the triangle, duo-trio, 3-AFC, 2-AFC, in which after every trial of the discrimination test the decision can be made to stop testing and declare a difference, to stop testing and declare no difference, or to continue testing. The sequential method often allows for a decision to be made after fewer trials of the discrimination test than would be required by conventional approaches that use predetermined numbers of assessments.Cross References:ISO 5492ISO 5495ISO 6658ISO 10399ISO 8586ISO 4120ISO 3534-1All current amendments available at time of purchase are included with the purchase of this document.
