TS 12699

TS 12699 is a vocational standard that defines the soft solderer profession, sets out how practitioners are classified, identifies the minimum tools and equipment used in the occupation, and addresses how the required attributes of each class are measured and assessed.

What soft soldering competence means in practice

Soft soldering joins parts by applying a filler metal with a relatively low melting temperature to the joint area. In general technical terms, the solder wets the prepared surfaces and forms a continuous bond without fully melting the base metal. That makes surface cleanliness, heat control, and suitable material choice central to a sound joint. The focus of this standard is the professional definition, classification, and competency assessment of the worker, rather than a detailed process specification for soldering itself.

Main areas covered by the standard

• Definition and classification of the person performing the work
• Minimum tools and equipment used in the occupation
• Required characteristics and qualifications for each class
• Measurement and evaluation of those characteristics

In general industry use, soft soldering appears in electronic assembly, cable terminations, and small metal joining tasks. Good practice relies on controlled heating, proper surface preparation, and the correct soldering method for the materials involved. Because TS 12699 provides a shared vocational framework for the occupation, it is useful for understanding job roles, skill levels, and workforce qualification in this field.
