TS EN 15826

TS EN 15826 is a terminology standard for the field of vitreous and porcelain enamels. It is intended to establish a shared technical vocabulary for enamel technology, so that materials, processes and related concepts are understood consistently across production, inspection and specification contexts.

Why terminology matters in enamel technology

Vitreous and porcelain enamels are glass-based coatings used on metal substrates to provide protective and decorative surfaces. In this field, terminology helps distinguish closely related concepts such as raw materials, preparation, application, firing, bonding to the substrate and final surface behaviour. A terminology standard does not introduce a new test method or product requirement; it supports precise communication by defining the terms used by specialists.

What this standard covers

• It defines a number of terms related to vitreous and porcelain enamels and their technology.
• The list is not complete; it includes only those definitions considered necessary for correct and adequate understanding.
• Its purpose is to clarify technical processes and concepts, rather than to act as a process specification or performance standard.

In general technical terms, enamel coatings are fused at elevated temperature to form a hard, dense surface with good chemical resistance and a characteristic glass-like finish. The terms “vitreous” and “porcelain” point to this glassy nature and to the established vocabulary of the sector. This standard supports that vocabulary; it does not, from the title and scope alone, prescribe product selection rules or conformity criteria.
