Slate and stone for discontinuous roofing and external cladding - Part 2: Test methods

This document specifies test methods for slate, carbonate slate, schist and schistose stone for discontinuous roofing and external cladding, as defined in 3.1, 3.2, and 3.3 of EN 12326-1:2014 and 3.1 of prEN 12326-3:2021, used for assembly into discontinuous roofs and external wall cladding. In this sense, when the test describes a slate, it could also be considered as carbonate slate.
