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 prepared clay, with or without additives.
All or part of their surface can be covered with an engobe or glaze. The principal types of tile are:



EN 1304:2005 (E) 5 3.1.1.1 special tiles tiles made to shapes that vary from tile to tile for aesthetic reasons, for example hand-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 They can be used to obtain variable headlaps. 3.1.1.4 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 headlock 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 These tiles are generally rectangular, but can have a specially 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 headlaps or where their headlap is fixed due to the presence of lugs on the tiles. 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 of fittings: 3.2.2 coordinated fittings fittings that are intended to align or dimensionally interlock with the tiles with which they are to be laid (e.g. interlocking verge tile, interlocking ventilation tile, tile-and-a-half, interlocking ridge tiles, interlocking or aligning hip tile, aligning valley tile, interlocking or aligning angle tiles)



EN 1304:2005 (E) 6 3.2.3 uncoordinated fittings fittings that are not required to align or interlock with the tile with which they are to be laid (e.g. ridge tiles, hip tile, valley tile, verge tile, angle tiles) 3.3 Definitions specific 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 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 Three examples of interlock are shown in Figure 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 successive courses are aligned 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 Certain types of tiles or coordinated fittings are designed to be laid either straight bonded or broken bonded.



EN 1304:2005 (E) 7 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 the 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 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 In general, the same units are used as under tiles when laid with their concave side facing 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 equipped 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 fitting or to improve its characteristics 3.5.2 efflorescense crystalline deposit of soluble salts found on the surface of tiles or fittings due to water migrating from within the tiles or fittings and evaporating on the surface 3.5.3 Ceramic coating

NOTE Comments on appearance characteristics are given in Annex B. 4.2 Fixing Tiles and fittings may be provided with nibs and/or fixing holes but other means of fixing are permitted. NOTE 1 Over and under tiles do not necessarily have a nib. NOTE 2
Codes of practice in certain countries recommend two nail holes for certain types of tiles. When tiles and fittings are used as vertical cladding, they shall have appropriate means by which they may be fixed to an underlying support. 4.3 Geometric characteristics 4.3.1 General The geometric requirements are not applicable to uncoordinated clay fittings and special tiles. For the coordinated fittings only the relevant geometric characteristics that are necessary for their proper installation have to be determined.

4.3.4 Dimensions and dimensional tolerances 4.3.4.1 General Individual dimensions or cover dimensions shall be measured according to the methods described in EN 1024.
For tiles and coordinated fittings with sidelock and headlock, and tiles or coordinated fittings with sidelock only (for the latter, in the transverse direction only), the manufacturer may choose between the declaration of the individual dimensions (a,b) or the cover dimensions (c,d), see Figure 3. Conformity to this document will thus be assessed with respect to the characteristic chosen by the manufacturer. For over and under tiles with lugs to fix the headlap, the manufacturer shall declare only the overlapped dimensions. For all other tiles or coordinated fittings, the measurements declared by the manufacturer shall be of individual products.
Key a and b: Dimension of an individual product
c and d: Dimension of an overlapped group of products Figure 3 — Example of determination of the tile dimensions



EN 1304:2005 (E) 13 4.3.4.2 Individual dimensions The mean values of the length and width of tiles, measured according to the methods described in EN 1024, shall fall within ± 2,0 % of the values declared by the manufacturer. This requirement does not apply to the width of over and under tiles. 4.3.4.3 Cover dimensions (gauge) The measured value of the mean cover dimension shall fall within ± 2,0 % of the cover dimension declared by the manufacturer. For tiles with sidelock and headlock with a variable longitudinal gauge, the measured maximum gauge shall not be smaller than that declared by the manufacturer. For tiles with sidelock and headlock with a variable transverse gauge, the measured maximum transverse cover dimension shall not be smaller than that declared by the manufacturer. 4.4 Physical and mechanical characteristics 4.4.1 Impermeability 4.4.1.1 General After carrying out the test in accordance with Method 1 or 2 as described in EN 539-1, the clay tiles and fittings shall be classified in one of the two impermeability categories given in descending order below. Tiles or fittings for roofs classified in Category 2 shall only be used with watertight roofing underfelt. The manufacturer shall state which method he uses for his tests and the results shall be evaluated with reference to that method. 4.4.1.2 Category 1 a) Test method 1 The mean impermeability factor for test pieces after testing shall be 0,5 cm3/cm2 per day or less, and all individual results shall be 0,6 cm3/cm2 per day or less. b) Test method 2 The mean impermeability coefficient for test pieces after testing shall be 0,8 or less, and all individual results shall be 0,85 or less. 4.4.1.3 Category 2 a) Test method 1 The mean impermeability factor for test pieces after testing shall be 0,8 cm3/cm2 per day or less, and all individual results shall be 0,9 cm3/cm2 per day or less. b) Test method 2 The mean impermeability coefficient for test pieces after testing shall be 0,925 or less, and all individual results shall be 0,95 or less.



EN 1304:2005 (E) 14 4.4.2 Flexural strength The flexure strength criteria are not applicable to fittings. The test pieces shall be considered satisfactory if, when subjected to the test method described in EN 538, they support without breaking a load of at least:  600 N for plain tiles,  900 N for flat interlocking tiles,  1000 N for under and over tiles,  1200 N for other types of tiles. 4.4.3 Frost resistance The test pieces shall pass the test method(s) in accordance with EN 539-2 using the method valid for the country of use of the roofing tiles. NOTE 1 Except for countries already listed in Annex C, CEN members should state in a national document which test method(s) are acceptable. NOTE 2 The different physical and mechanical characteristics mentioned above are independent of one another; thus a high water absorption measured for one tile does not necessarily imply that this tile has a low frost resistance, and vice versa. 4.5 Fire performance 4.5.1 External fire performance 4.5.1.1 Requirements Where the manufacturer wishes to declare the external fire performance of clay roofing tiles and fittings for pitched roof coverings (e.g. where subject to regulatory requirements), the products shall be evaluated according to the provisions of 4.5.1.2 or 4.5.1.3. 4.5.1.2 Products satisfying the requirements for external fire performance, without the need for testing Products covered by this document meet the requirements for external fire performance, without the need for testing, in Class Broof (for all test methods) provided that they satisfy the definitions given in Commission Decision 2000/553/EC (1), i.e.:  they satisfy the provisions of Commission Decision [96/603//EC (2)] and
 any external coating are inorganic. For this purpose the calorific value or mass of the organic coating shall be measured over the coated area only. NOTE Member States may have national “deemed to satisfy” lists, which include more products than those given in Decision 2000/553/EC. 4.5.1.3 Other products Products not covered by 4.5.1.2 shall be tested and classified, using the method valid in the country of use of the products, in accordance with the provisions of prEN 13501-5. The products to be tested shall be installed,



EN 1304:2005 (E) 15 in addition to the general provisions given in the test methods, in a manner representative of their intended end use. 4.5.2 Reaction to fire performance 4.5.2.1 Requirements Where the manufacturer wishes to declare the reaction to fire of the products (e.g. where subject to regulatory requirements), the products shall be evaluated according to the provisions of 4.5.2.2 or 4.5.2.3. 4.5.2.2 Products satisfying the requirements for the fire reaction Class A1, without the need for testing Tiles and fittings are classified Class A1 for the characteristic reaction to fire, in accordance with the provisions of Commission Decision [96/603/EC (2)], as amended, without the need for testing, provided that:  for tiles and fittings made by gluing one or more clay components together, the organic content of the hardened glue is ≤ 0,1 % by weight or volume (whichever is the lower) and  they contain ≤ 1,0 % by weight or volume (whichever is the lower) of homogeneously distributed organic material (other than glue). 4.5.2.3 Other products Products not meeting the requirements of 4.5.2.2 shall be tested and classified in accordance with EN 13501-1. The products to be tested shall be installed, in addition to the general provisions given in the test method(s) and where appropriate, in a manner representative of their intended end use. 4.6 Release of dangerous substances For products used within the European Economic area, see Annex ZA, Note to ZA.1. 5 Marking and labelling At least 50 % of all types of tile and at least 10 % of fittings delivered shall bear indelible and legible marking (in code or in full) enabling the identification of:  manufacturer and the factory,  type of product (optional),  country of origin,  year and month of production. The delivery documents shall refer to this EN 1304 and specify the impermeability Category 1 or 2 plus the test method used according to EN 539-1 and which frost test method(s), A, B, C and D of EN 539-2 the product has successfully passed. The technical literature describing the product shall also state the dimensions and the declared camber or cambers, when relevant.



EN 1304:2005 (E) 16 6 Evaluation of conformity 6.1 General The compliance of the tiles and fittings covered by this document with the requirements of this document and with the stated values and classes (including method(s) and category) shall be demonstrated by:  initial type testing;  factory production control by the manufacturer. For the purposes of initial type testing and factory production control, the tiles and/or fittings may be grouped into families where it is considered that test results for the selected characteristic(s) from one product within the family are valid for all tiles and/or fittings within that family. 6.2 Initial type testing Initial type testing shall be performed to show conformity with this document according to Table A.1. Tests previously performed in accordance with the provisions of this document (same product, same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account. In addition, initial type testing shall be performed at the beginning:  of the production of a new tile or fitting (unless a member of the same family),  of a new method of production (where this may affect the stated properties). Whenever a change occurs in the product design, the raw material or the production process (subject to the definition of a family), which may change significantly one or more of the characteristics, the type tests or assessments shall be repeated for the appropriate characteristic(s). NOTE If tests are carried out on tiles taken from a site after the delivery, only the test results for the geometric and impermeability criteria can be used without interpretation. 6.3 Factory production control The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market are in conformity with the requirements in this document. The FPC system shall consist of procedures, regular inspections and tests and/ or assessments. The permanent internal control of production and of the finished product exercised by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures and include the necessary corrective action if a non conformity occurs. The manufacturer may choose different methods:  minimum frequency of product tests for Factory Production Control as given in Table A.2,  statistical method, where the level of the compliance of the product and/or process shall be declared and demonstrated by the manufacturer. Alternative test methods may be used for
