TS 12804

TS 12804 is a vocational standard for the manufacturer and installer of solar energy water-heating systems. It defines the occupation, sets out how practitioners are classified, and addresses the minimum tools, equipment, and competencies associated with carrying out this profession, together with how the required characteristics are measured and evaluated.

Technical context of the occupation

Solar water-heating systems use solar heat to prepare domestic hot water. In general technical terms, performance depends on the coordinated operation of collectors, storage tanks, piping, fittings, and installation layout, while workmanship affects efficiency, leakage control, heat losses, and overall reliability. This standard provides a vocational framework for the people who manufacture and install such systems, focusing on the professional profile and the minimum equipment expected in practice.

Classification and assessment of competence

The standard organizes the occupation by level and links each class to the characteristics that should be present and assessed. This is typical of occupational standards: job scope, skill level, equipment use, and practical competence are described separately so that the profession has a clearer technical language. As a result, manufacturing and installation work in the solar water-heating field can be discussed and evaluated against a more structured occupational framework.

• Occupation definition and classification
• Minimum tools, materials, and equipment
• Expected characteristics for each class
• Measurement and evaluation of those characteristics
