25、EN 12326-1 is one of a series of product standards for building materials. EN 12326 consists of the following parts: Part 1: Specifications for slate and carbonate slate; Part 2: Methods of test for slate and carbonate slate. According to the CEN-CENELEC Internal Regulations, the national standards
26、organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembo

BS EN 12326-1:2014EN 12326-1:2014 (E) 5 Introduction The evaluation of the performance of the products has been defined, as far as possible, in terms of a number
28、 of type tests. A distinction has been made between product appraisal (type test) and routine factory production control requirements. The performance of a roof or wall constructed with these products depends not only on the properties of the product as required by this document, but also on the des
29、ign, construction and performance of the roof or wall as a whole in relation to the environment and conditions of use. BS EN 12326-1:2014EN 12326-1:2014 (E) 6 1 Scope This European Standard specifies requirements for slate and carbonate slate for discontinuous roofing and external cladding, as defin
30、ed in 3.1, and 3.2, used for assembly into discontinuous roofing and external cladding. For the purposes of this European Standard, slates and carbonate slates have been classified. This European Standard does not apply to products for roofing or external cladding made from the following: a) stone o
31、ther than those defined in 3.1 and 3.2; b) concrete; c) polymeric materials; d) fibre reinforced cement; e) metal; f) clay. This European Standard is not applicable to roofing and cladding slates used internally. This European Standard is not applicable to bonded cladding (cladding fixed with adhesi
32、ves) and cladding fixed with dowels and cramps. NOTE 1 Requirements for internal wall lining slate are specified in EN 1469. This document does not include requirements for appearance. NOTE 2 Some general guidance for appearance is given in Annex A. This European Standard does not include installati
33、on rules for slates. NOTE 3 References to national recommendations on methods of construction for slate roofs are given in Annex C. NOTE 4 Where the term “slate” is used in this document it means slate and carbonate slate unless otherwise indicated. 2 Normative references The following documents, in
34、 whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12326-2:2011, Slate and stone f

37、 including sediments of volcanoclastic origin and belonging petrographically to a range which begins at the boundary between sedimentary and metamorphic formation and ends at the epizonal-metamorphic phyllite formations Note 1 to entry: The predominant and most important components are the phyllosil
38、icates 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 te
39、ctonic 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 appa
40、rent 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 thicknes
41、s 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 tha
42、t 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 d
43、escription does not apply to special designs of slates. 3.9 shouldered slate slate from which the upper corners have been removed BS EN 12326-1:2014EN 12326-1:2014 (E) 8 3.10 type test product appraisal test concerned with one or more of the following, the effect of which cannot be anticipated on th
44、e basis of previous tests: the operation of a new quarry, mine or vein of slate for the first time; an unanticipated change in the geology of the rock 3.11 factory production control test test performed on samples drawn from continuous production to establish whether a lot conforms to this document
45、3.12 nominal thickness thickness of slates declared by the manufacturer 3.13 corrected packed thickness thickness of 100 packed slates divided by 100 and reduced by a factor depending on the flatness characteristics of the slate declared by the manufacturer Note 1 to entry: See Annex E. 3.14 basic i
46、ndividual thickness thickness of slates determined from the modulus of rupture, as shown in Annex B, and/or from traditional construction methods Note 1 to entry: See Annex B and Annex C. 3.15 minimum individual thickness minimum thickness of slates determined by adjusting the basic individual thick
47、ness in accordance with 5.2.3 3.16 modulus of rupture maximum stress sustained by a slate test piece when a bending moment is applied Note 1 to entry: In this document, the arrangement of the test is three point bending. 3.17 random slates slates or sets of slates produced to undefined dimensions 4
