TS ISO 2395

TS ISO 2395. OFFICIAL SCOPE IS UNAVAILABLE. This standard is a vocabulary document for test sieves and test sieving, focusing on the terms used to describe sieving equipment, the sieving process, and the related concepts used in particle size analysis. Its purpose is to support consistent technical language in laboratory testing and classification of granular materials.

Core terms used in sieving practice

Test sieves are screening tools with defined aperture sizes, used to separate particles according to size. Test sieving is the process of passing a material sample through a sieve to divide it into coarser and finer fractions. In general technical context, vocabulary standards like this help align meanings for terms such as nominal aperture size, sieve surface, fraction, sample, sieving efficiency, and particle size distribution. That consistency matters when comparing results across laboratories or when documenting analytical methods.

Why vocabulary control matters in particle size analysis

Sieving is both a separation operation and a measurement method for describing the size distribution of particles. If different users apply the same term differently, reports and test methods become harder to compare. A vocabulary standard addresses that problem by defining the language surrounding test sieves and sieving, helping users distinguish the equipment from the process and the process from the analytical result. Based on the title and bibliographic data, this document is identifiable as a terminology standard; those details do not by themselves confirm specific test requirements, numerical limits, or apparatus specifications.

In wider technical practice, test sieving is commonly used for powders, granules, and aggregate materials. Aperture size determines the cut between larger and smaller particles, while particle shape, moisture, and agglomeration can affect how material passes through a sieve. By standardising the terms used in this field, the standard supports clearer communication in measurement, reporting, and laboratory documentation.
