TS 4921

TS 4921 is a complementary terminology standard for sensory analysis, organizing terms and definitions used in the field and extending the vocabulary set already addressed in TS 3707. It brings together additional sensory-analysis concepts and gives them a shared technical meaning so that the same term is understood consistently in laboratory, quality, and product-development contexts.

Why terminology matters in sensory analysis

Sensory analysis relies on human perception of appearance, aroma, taste, texture, and overall impression. In practice, that means the language used to describe panels, attributes, responses, and evaluation conditions must be precise. A terminology standard does not prescribe a test method; instead, it supports communication by defining the concepts behind the words used in the discipline.

For users working with sensory testing, the value of TS 4921 lies in its role as a companion reference: it fills in terms that are outside the scope of TS 3707 and helps maintain consistency across reporting, training, and technical documentation. That makes it useful wherever sensory judgments need to be described in a disciplined and repeatable way.
