TS 12674

TS 12674 is a vocational standard for aluminium framework joiners. It defines the occupation and the people who perform it, sets out how the occupation is classified, and frames the minimum level of competence expected in this field. In practical terms, aluminium framework joinery concerns the preparation, assembly and fitting of building elements such as doors, windows and similar frames made from aluminium profiles and related joining components. The standard also covers the basic tools and equipment used in the trade, together with the measurement and assessment of the characteristics expected from different classes of practitioner.

What the occupation involves

Aluminium joinery combines metalworking with installation skills. Typical work in this field involves measuring, cutting, drilling, fastening, joining and adjusting profile components so that the finished assembly fits correctly and performs as intended. Aluminium is valued in building applications because it is lightweight, corrosion-resistant and easy to work with, which makes dimensional accuracy and proper tool selection especially important.

What this standard covers

• Definition of the occupation and the people who perform it
• Classification within the profession
• Minimum tools, equipment and accessories used in the trade
• Measurement and evaluation of the characteristics required for each class
• Exclusion of joinery professions made from other materials

TS 12674 therefore serves as a shared vocational reference for the aluminium framework trade rather than a step-by-step installation manual. In real-world use, marking accuracy, cutting precision, joint quality, fit during installation and the correct choice of basic tools all matter for consistent results; within this listing, however, these issues are addressed at the level of profession definition and assessment framework.
