The document specifies a method for determining whether there is a difference between two products. This difference may relate to one specific organoleptic attribute or to a combination of organoleptic attributes. The method is not applicable for the determination of preference, nor for the evaluation of the character or intensity of the perceived difference. Two forms of this test are described: The balanced-reference technique and the constant-reference technique. The method is statistically less efficient than the triangle test described in DIN EN ISO 4120, but is easier to perform by the assessors.
