16、reword This document (EN 1304:2013) has been prepared by Technical Committee CEN/TC 128 “Roof covering products for discontinuous laying and products for wall cladding”, the secretariat of which is held by IBN. This European Standard shall be given the status of a national standard, either by public
17、ation of an identical text or by endorsement, at the latest by November 2013, and conflicting national standards shall be withdrawn at the latest by November 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC
18、 shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1304:2005. In comparison to the previous edition, the following clauses are changed: 4.4.3, 4.6, Annex C and Annex ZA. This document has been prepared under a mandate given to CEN by the Europea
19、n Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This document is part of a package of standards on clay roofing tiles and fitting
20、s. According to the CEN-CENELEC Internal Regulations, the national standards 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,
21、Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 1304:2013EN 1304:2013 (E) 4 1 Scope This European Standard specifies requireme
22、nts for clay roofing tiles and fittings for pitched roof coverings and wall cladding and lining. It applies to all tiles and fittings as defined in Clause 3. Clay roofing tiles and clay fittings which conform to this European Standard are suitable for use as roof coverings, vertical wall cladding an
23、d lining. This European Standard defines the minimum requirements for a product which if satisfactory at the time of delivery will ensure that the product is able to perform its function in relation to the performance levels declared for it, whilst subjected to the changes that occur in such materia
24、ls during normal conditions of use. The results obtained according to the European Standard apply to products at the time they are offered for sale. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicat
25、ion. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

28、rms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 General 3.1.1 clay roofing tiles products for discontinuous laying on pitched roofs, and for wall cladding, which are manufactured by shaping (extrusion and/or pressing), drying and firing of the pr
29、epared clay, with or without additives Note 1 to entry: All or part of their surface can be covered with an engobe or glaze. BS EN 1304:2013EN 1304:2013 (E) 5 The principal types of tile are: 3.1.1.1 special tiles tiles made to shapes that vary from tile to tile for aesthetic reasons, for example ha
30、nd-made tiles 3.1.1.2 tiles with sidelock and headlock tiles with one or more longitudinal and transverse interlocking device(s) 3.1.1.3 tiles with sidelock only tiles with a longitudinal interlocking device but no transverse one Note 1 to entry: They can be used to obtain variable headlaps. 3.1.1.4
31、 tiles with headlock only tiles with a transverse interlocking device but no longitudinal one 3.1.1.5 tiles with variable headlap tiles with sidelock and headlock where the design of the tiles allows them to be fixed at varying headlaps 3.1.1.6 tiles with variable sidelap tiles with sidelock and hea
32、dlock where the design allows variation in the amount of sidelap 3.1.1.7 plain tiles tiles usually with a flat surface that can be slightly cross cambered and/or longitudinally cambered and which have no interlocking system Note 1 to entry: These tiles are generally rectangular, but can have a speci
33、ally shaped tail (e.g. fish-scale tiles with a rounded or sharp front edge). 3.1.1.8 overlapping tiles tiles which have no side or headlock and are profiled in an “S“ shape 3.1.1.9 over and under tiles tiles with the shape of a gutter whose design makes it possible either to fix them with variable h
34、eadlaps or where their headlap is fixed due to the presence of lugs on the tiles Note 1 to entry: They are made with their edges either parallel or forming a cone. 3.2 General 3.2.1 clay roofing fittings products that are complementary to the tiles and have a technical function There are two types o
35、f fittings: BS EN 1304:2013EN 1304:2013 (E) 6 3.2.2.1 coordinated fittings fittings that are intended to align or dimensionally interlock with the tiles with which they are to be laid EXAMPLE interlocking verge tile, interlocking ventilation tile, tile-and-a-half, interlocking ridge tiles, interlock
36、ing or aligning hip tile, aligning valley tile, interlocking or aligning angle tiles 3.2.2.2 uncoordinated fittings fittings that are not required to align or interlock with the tile with which they are to be laid EXAMPLE ridge tiles, hip tile, valley tile, verge tile, angle tiles 3.3 Definitions sp
37、ecific to tiles and fittings with sidelock and headlock and tiles with sidelock only 3.3.1 General 3.3.1.1 interlock system designed for the assembly of two adjoining tiles or fittings and usually including one or more raised parts called “ribs“ and one or more concave parts called “grooves“ 3.3.1.2
38、 longitudinal interlock system allowing two tiles or fittings in the same horizontal course to be fitted together 3.3.1.3 transverse interlock system allowing two tiles or fittings from successive horizontal courses to be fitted together Note 1 to entry: Three examples of interlock are shown in Figu
39、re 1. The arrangement of ribs and grooves limits the extent of movement between the tiles and improves the resistance to the ingress of water. Figure 1 Examples of interlock 3.3.2 straight bond tiles and fittings tiles or coordinated fittings designed to be laid so that the longitudinal joints of su
40、ccessive courses are aligned BS EN 1304:2013EN 1304:2013 (E) 7 3.3.3 broken bond tiles and fittings tiles or coordinated fittings designed to be laid so that the longitudinal joints are shifted half a tile between successive courses Note 1 to entry: Certain types of tiles or coordinated fittings are
41、 designed to be laid either straight bonded or broken bonded. 3.3.4 flat interlocking tiles and fittings interlocking tiles or coordinating fittings whose visible surface has no rib separating the areas of water flow from the longitudinal interlocks and where the longitudinal interlocks lie below th
42、e areas of water flow (see Figure 2) Key 1 areas of water flow 2 interlock Figure 2 Cross section and diagram of principle 3.4 Definitions specific to over and under tiles 3.4.1 under tiles tiles designed to be laid with their concave side facing upward and resting on the roofing support Note 1 to e
43、ntry: Under tiles may have no nib, or one or more nibs for laying on battens. 3.4.2 over tiles tiles designed to be laid with their concave side facing downward and straddling two under tiles Note 1 to entry: In general, the same units are used as under tiles when laid with their concave side facing
44、 upward and over tiles when they are laid with their concave side facing downward. However, the profile of under tiles can differ from that of over tiles; they can have, for example, a flat base or a shape allowing for the seating of the product on its support. In the latter case, under tiles are eq
45、uipped with two lateral upright sides. 3.4.3 over and under tiles with lugs to fix the headlap over and under tiles with lugs to fix the longitudinal overlap 3.5 Further definitions 3.5.1 additive material added in small quantities to the clay mix so as to facilitate the manufacture of the tile or f
