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.

This document specifies a method for the determination of the softening point of bitumen and bituminous binders in the range of 28 °C to 150 °C. The method described also applies to bituminous binders that have been recovered from bituminous mixes, e.g. by extraction according to EN 12697 3 [1]. The change from mercury thermometers to electronic temperature devices has revealed that the temperature definition in the mercury thermometer has not been precise enough to make a correct, unbiased transfer to electronic devices. Care should be taken for softening points ring and ball above 100 °C as the condition may have changed from previous practice to present days testing equipment. Below approximately 100 °C the difference in temperature readings between electronic and mercury stem thermometer is acceptable compared to the repeatability of this test method.

This document specifies a method for determining the dimensional stability (i.e. the shrinkage and swelling) of cementitious screed, calcium sulphate screed, magnesite screed and synthetic resin screed materials made in accordance with EN 13892-1.
