21、s”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2004, and conflicting national standards shall be withdrawn at the latest by December 2004.
22、This document has been prepared under Mandates M119 and M122 given to CEN by the European 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 doc
23、ument. EN 13748 consists of the following parts, under the general title “Terrazzo tiles“ : Part 1: Terrazzo tiles for internal use Part 2: Terrazzo tiles for exterior use Terrazzo tiles for exterior use are different from concrete paving flags covered by EN 1339, Concrete paving flags. Main differe
24、nces are that the priority is given in EN 13748-2 to decorative aspects and mechanical requirements are different. For information, decorative products, similar to flags, with limited mechanical properties intended to be used in exterior for exclusive pedestrian circulation are covered by EN 13198.
25、According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Li
26、thuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 13748-2:2004 (E) 5 1 Scope This European Standard specifies materials, properties and methods of testing for unreinforced cement-bound terrazzo tiles which are fac
27、tory made and sold ready to be placed. The tiles are intended for external use (including roofing applications) in pedestrian areas, e.g. walkways, terraces, commercial centres and swimming-pools, etc, where the decorative aspect of the covering is predominant. NOTE This standard applies to ex-facto
28、ry products and does not take into account the laying of the product. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are lis
29、ted hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

34、 with this standard. The tiles may be single or dual layered. EN 13748-2:2004 (E) 6 They are either individually produced by compression and/or vibration, or cast as large cement-bound mineral aggregate sheets or blocks by means of vibration and/or compression and/or vacuum, before being cut to size
35、 3.2 single-layered terrazzo tiles terrazzo tiles made in a single homogeneous layer of granules or chippings of a suitable aggregate embedded in a paste of grey or white cement and water. Admixtures and additions may be used 3.3 dual-layered terrazzo tiles terrazzo tiles made up of a facing or wear
36、 layer whose composition is similar to single-layered terrazzo tiles and a second layer known as the backing or base concrete layer whose surface is not exposed during normal use and which in the case of a calibrated tile will be partially removed by specialised processing 3.4 work dimension any dim
37、ension of a terrazzo tile specified for its manufacture to which the actual dimension should conform within specified permissible deviations 3.5 actual dimension dimension of a terrazzo tile as measured 3.6 format dimensions of a terrazzo tile as specified in commercial terms, mostly in rounded figu

39、ile of materials and/or properties different to the main body or backing layer of a terrazzo tile 3.11 slip resistance property of the surface to maintain the adherence of a pedestrian foot 3.12 declared value value for a requirement as declared by the manufacturer, taking into account the accuracy
40、of the test and the variability of the manufacturing process 3.13 textured upper face not flat upper face, with a regular texture pattern EN 13748-2:2004 (E) 7 4 Requirements 4.1 Materials 4.1.1 General Only materials with established suitability shall be used. The suitability requirements of the ma
