21、 the secretariat of which is held by BSI. 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of an identical text or by endorsement, at the latest by May 2013, and conflicting national standards shall be withdrawn at the latest by August 2014. Attention is
22、 drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1343:2001. This document has been prepared under a mandate given to CE
23、N 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 document. The following changes have been made in this new edition: a) Wher
24、e possible the requirements refer to separate test methods prepared by CEN/TC 246, “Natural stones“. The change was made to allow those placing the products on the market to use the same test results for a number of products. b) The values to be declared have been clarified and where applicable the
25、declared values are now lower expected values. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, For

28、d for external paving and road finishes. External paving use includes all pavements typical of road works, such as pedestrian and trafficked areas, outdoor squares and similar to be used in an outdoor condition that are subject to the weathering agents, such as temperature changes, rain, ice, wind,
29、etc. This European Standard provides also for the evaluation of conformity and for marking of the natural stone slabs. This European Standard also covers characteristics that are of importance to the trade. 2 Normative references The following documents, in whole or in part, are normatively referenc

The manufacturer shall state the minimum and maximum working length of a kerb unit. The ends of curved kerbs sh
45、all be radial. Curved kerbs shall be identified by the radius of the vertical visible or traffic face. The overall length of a number of curved kerbs shall be measured without the joints on the edge common to the visible faces. The minimum length of curved kerbs shall be 500 mm. Nominally square arr
46、ises may have a chamfer with vertical and horizontal dimensions not exceeding 2 mm. The dimensions of larger chamfers, radiused corners and splays, when used, shall be declared by the supplier. Examples of typical kerb cross-sections are shown in Figure 3. 4.1.2 Denomination The denomination shall a
47、lways be declared in accordance with EN 12440 (meaning traditional name, petrological family, typical colour and place of origin as precisely as possible for example geo coordinates). 4.1.3 Alteration of physical properties of the natural stone If during production the natural stone kerbs have been
48、subjected to a treatment that physically alters the properties of the stone (e.g. chemical treatment, patching, or filling or other similar products for natural holes, faults or cracks), then the use of such treatment shall be stated. In addition, specimens for testing shall be representative of the product and any processes that the stone is subjected to. 4.2 Dimensions 4.2.1 Overall width and height The overall width and height as laid shall be measur
