CE Marking of Clay RoofingTiles (UNI EN 1304), does not have the purpose of highlighting all the characteristics of products, but only some “essential” requirements aimed at guaranteeing users safety and comfort. For this reason is far from being a quality mark, it simply denotes that products are suitable for the envisaged use.
In reverse, AC Service is a far more complete product qualification activity. It comprises a set of tests which is wider than the bare minimum requested to obtain the CE Marking. The Service does not only provide a higher number of tests (see Table below), but it has to be renewed yearly.
