TS 12563

TS 12563 is a vocational standard for the refrigerating system installation technician. It defines the occupation, sets out its classification, and addresses the characteristics and assessment criteria for technical personnel at different levels, together with the tools, equipment, and hardware used in this field. In practical terms, it provides a common reference for how refrigeration installation work is understood and evaluated.

What the occupation involves

From a general technical perspective, refrigeration installation work is concerned with assembling and preparing refrigeration systems so they can operate as intended. A refrigeration plant typically combines components such as compressors, condensers, expansion devices, evaporators, piping, and control elements. Because these systems depend on correct mechanical assembly and proper interaction between components, the occupation requires both hands-on installation skills and a working understanding of refrigeration fundamentals.

Classification and assessment in practice

A notable feature of this standard is that it treats the occupation across different classes or technical levels rather than as a single uniform role. In general occupational terms, that means the expected competence of an entry-level technician can be distinguished from that of a more experienced technical worker. The inclusion of measurement criteria and their evaluation points to a performance-based approach that values not only knowledge, but also the ability to carry out work to the technical requirements of the job.
