The values given in the table are the most common or generally accepted for each product, hence they are only estimates. To identify what group of the standard they actually belong to, you shall refer to section 'Standard classification'.

DENOMINATION
It is the most common denomination of a wide variety of products with very different characteristics that only coincide in their rustic appearance. They are frequently manufactured in small production units and are handmade. They must not be confused with mass produced stoneware tiles with a rustic finish.
ASPECTO

The body is earth-coloured and irregular, with a very heterogeneous grain. Grains, pores, incrustations, etc., may be perceived by the naked eye. The surfaces and arrises, even on the face, possess the irregularities that are typical of this variety and are accepted and may even be international. There is a wide range of shapes and sizes.
USO
The characteristics of the tiles make them specially and almost exclusively apt for buildings or rooms with a rustic look. Given these characteristics, the possibility that their face may require to be treated before or after laying for reasons of appearance (lustre) or functionality (impermeability) must be foreseen.
  CLASIFICATION STANDARDS
  These tiles are mainly included in group AIIb 2nd part (Extruded ceramic tiles with 6% < E < 10%, 2nd part water absorption) and group AIII (Extruded ceramic tiles with E > 10% water absorption) of standards ISO 13006 and UNE EN 14411.
