TS 12373

TS 12373 is a vocational standard for the repairman of gasoline engines, setting out the professional definition and classification of the occupation and the basic framework of the job. It also addresses the tools, equipment and devices used in the work, together with the knowledge and skills expected from each class of worker involved in gasoline engine repair.

What gasoline engine repair involves

From a general technical perspective, gasoline engine repair covers diagnosis, maintenance and repair of internal combustion engines and the subsystems that support them, such as ignition, fuel delivery, air intake, lubrication and cooling. The work is not limited to replacing parts; it also requires interpreting symptoms such as loss of power, irregular running, excessive consumption, noise and mechanical wear. In this standard, the central focus is the definition of the occupation and the competence profile needed to perform it.

Tools, equipment and competence in one framework

For an engine repairman, suitable hand tools, measuring instruments and workshop equipment are essential for fault finding, disassembly and reassembly, and checking adjustments. Professional competence also includes distinguishing between systems, following the correct maintenance sequence and working in an orderly and safe manner. This standard brings the occupational definition, equipment needs and knowledge-and-skill requirements together in a single vocational framework.
