Note 1 to entry: The predominant and most important components are the phyllosilicates and the cleavage resulting froma schistosity flux, caused by low or very low grade of metamorphism. Note 2 to entry: Slate is distinguished from sedimentary stones, which invariably splits along a bedding or sedimentation plane. Note 3 to entry: The origin of the metamorphism can be due to tectonic or lithostatic compression or a combination of the two. 3.2 roofing slate slate used for roofing and external cladding, which easily splits into thin sheets along a plane of cleavage 3.3 carbonate slate rock used for roofing and external cladding, containing phyllosilicates and a minimum apparent calcium carbonate content of 20 % and exhibiting a prominent slaty cleavage 3.4 vein separately identifiable band of slate rock within the geological formation of a quarry or mine 3.5 slate vein localized occurrence (in a roofing or external cladding slate), usually passing through the thickness of a slate, of minerals that have intruded or infiltrated into a joint or fissure in the parent rock 3.6 grain orientation of the minerals in slate which results in an anisotropic bending strength Note 1 to entry: In the bending strength test, grain is perpendicular to the load bar in the test that usually gives the highest failure result. 3.7 rectangular slate slate which is square or rectangular including such slates which have been shouldered 3.8 shouldering removal of the upper (when installed) corner(s) of a roofing or external cladding slate to facilitate laying Note 1 to entry: This description does not apply to special designs of slates. 3.9 shouldered slate slate from which the upper corners have been removed SIST EN 12326-1:2014

Slates within code T3, which potentially can result in water penetration, should only be used selectively with suitable methods of construction which avoid such penetration (see Annex C). 5.8 Apparent calcium carbonate content The apparent calcium carbonate content, determined in accordance with EN 12326-2:2011, Clause 13, shall conform to the appropriate classification according to Table 1, as declared by the manufacturer. 5.9 Sulfur dioxide exposure test 5.9.1 Slates with an apparent calcium carbonate content of ≤ 20 %, determined in accordance with EN 12326-2:2011, Clause 13, shall be tested according to EN 12326-2:2011, 14.1, and shall be allocated a code as shown in Figure 2 depending upon the assessment criteria reported in the test. Slates shall conform to the apparent calcium carbonate content as declared by the manufacturer. The minimum individual thickness of a slate shall be in accordance with the sulfur dioxide exposure code S or the depth of softened layer in es, determined in accordance with EN 12326-2:2011, 14.2, as defined in Table 1. Any slates which achieve a code S3 may be tested according to EN 12326-2:2011, 14.2, to determine their minimum individual thickness according to 5.2.3.5. SIST EN 12326-1:2014

Small cracks and loosely attached flakes that are the result of the method of manufacture are permissible in so far as they do not prejudice the other requirements of this document. 5.12 Other dimensions 5.12.1 General The requirements of 5.12.2, 5.12.3, 5.12.4 and 5.12.5 shall not apply to slates made to undefined dimensions or non-rectangular formats. Requirements for rectangular slates, including shouldered rectangular roofing and external cladding slates, are specified in 5.12.2, 5.12.3, 5.12.4 and 5.12.5. Requirements for roofing and external cladding slates of other shapes or undefined dimensions are specified in 5.12.6. 5.12.2 Deviation of length and width When tested in accordance with EN 12326-2:2011, Clause 5, rectangular slates shall not deviate from the manufacturer's declared length or width by more than ± 5 mm.
