TS ISO 18650-2

TS ISO 18650-2 is a technical procedure standard for construction machinery that defines how the mixing efficiency of concrete mixers is to be examined. It focuses on batch-type and continuous-type concrete mixers, providing a common framework for assessing how effectively a mixer distributes the constituents of a concrete mix.

The standard refers to the mixer types defined in ISO 18650-1, so the equipment classification and terminology remain aligned within the same standard family. In general technical terms, “mixing efficiency” describes how uniformly the ingredients are distributed by the end of the mixing process. Such procedures are used to make performance examinations comparable across different machines and to support consistent evaluation under a shared method.

What the scope covers

• It applies to batch-type and continuous-type concrete mixers as defined in ISO 18650-1.
• It specifies the procedure and requirements for examining mixing efficiency.
• It applies to concrete mixers with a rated capacity greater than or equal to 70/50.
• It provides a common examination approach for assessing mixer performance.

In general technical context, concrete mixers are used to combine aggregate, cement, water and, where needed, admixtures to produce fresh concrete. Mixing efficiency is closely tied to practical outcomes such as homogeneity, ingredient distribution and batch consistency. This standard therefore serves as a structured method for examining that core machine function, without implying additional test areas or performance criteria beyond what is stated in the supplied scope.
