18、cal Committee CEN/TC 178 “Paving units and kerbs”, 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 wi

19、thdrawn at the latest by August 2014. 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 shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1343:2001. This docu

20、ment has been prepared under a mandate 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 document. The following c

21、hanges have been made in this new edition: a) Where 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 decl

22、ared have been clarified and where applicable the 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, Cypr

23、us, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United

24、 Kingdom. BS EN 1343:2012EN 1343:2012 (E) 5 1 Scope This European Standard specifies the performance requirements and the corresponding test methods for all natural stone kerbs used for external paving and road finishes. External paving use includes all pavements typical of road works, such as pedes

25、trian 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, etc. This European Standard provides also for the evaluation of conformity and for marking of the natural stone slabs. T

26、his 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 referenced in this document and are indispensable for its application.

For curved kerbs the length is the measured visible face circumference. The manufac

39、turer shall state the minimum and maximum working length of a kerb unit. The ends of curved kerbs shall 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 c

40、ommon to the visible faces. The minimum length of curved kerbs shall be 500 mm. Nominally square arrises 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. Exampl

41、es of typical kerb cross-sections are shown in Figure 3. 4.1.2 Denomination The denomination shall always 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

42、 of physical properties of the natural stone If during production the natural stone kerbs have been 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

43、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 measured in accordance with EN 13373:2003, 5.2, a
