TS EN 1304

TS EN 1304 is the standard that addresses product definitions and specifications for clay roofing tiles and the fittings used with them. It covers the clay-based products intended for pitched roof coverings as well as for wall cladding and lining applications. In practical terms, it helps define what these products are and which technical characteristics matter for their intended building use.

Product families covered by the standard

Roofing tiles are ceramic components designed to shed water and protect the roof surface from weather exposure. Fittings are the complementary pieces used at ridges, edges, ventilation points, and other special details where the main tile field must be completed. The standard’s focus is on the properties these clay products need when they are intended for pitched roofs and for wall cladding or lining, so the intended architectural function is central to the product definition.

Why the tile-and-fitting distinction matters

In clay roofing systems, performance is typically understood through properties such as watertightness, mechanical strength, dimensional stability, resistance to freeze-thaw effects, and surface behaviour. In general technical context, roof slope, detailing, and cladding layout influence the geometry and installation approach required for each piece. That is why the distinction between tiles and fittings is important: tiles form the main covering area, while fittings provide continuity and complete the system at junctions and special locations. This standard gives the product family a common technical vocabulary so that definitions and expected characteristics are understood within one framework.

• Covers clay products for pitched roof coverings.
• Also includes wall cladding and wall lining applications.
• Treats roofing tiles and fittings together as a product family.
• Provides a common framework for product definitions and specifications.
• Relates to ceramic building products used in roof and facade detailing.
