Organization: ASTM
Publication Date: 1 October 2004
Status: inactive
Page Count: 8
scope:

This test method covers a procedure for determining whether a perceptible sensory difference exists between samples of two products.

This test method applies whether a difference may exist in a single sensory attribute or in several.

This test method is applicable when the nature of the difference between the samples is unknown. It does not determine the size or the direction of the difference. The attribute(s) responsible for the difference are not identified.

Compared to the duo-trio test, the triangle test can achieve an equivalent level of statistical significance with fewer assessors. For details on how the triangle test compares to other three-sample tests, see Refs (1), (2), (3) and (4).(Footnote 2)

This test method is applicable only if the products are homogeneous. If two samples of the same product can often be distinguished, then another method, for example, descriptive analysis, may be more appropriate.

This test method is applicable only when the products do not cause excessive sensory fatigue, carryover or adaptation.

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 and health practices and determine the applicability of regulatory limitations prior to use.

Footnote 2 - The boldface numbers given in parentheses refer to a list of references at the end of the text.
