This European Standard shall be given the status of
19、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of an identical text or by endorsement, at the latest by May 2013, and conflicting national standards shall be withdrawn at the latest by August 2014.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 drawn to the possibility that some of the elements of this document may be the subject of pat
20、ent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1341:2001. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential r
21、equirements 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) Where possible the requirements refer to separate test methods prepared by CEN/TC 246, “Natural st
22、ones“. 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 declared values are now lower expected values. c) Annex A (Annex B in the 2001 version) has be
23、en extended to include safety factors specific to different uses. 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, Es

25、1:2012 (E) 5 1 Scope This European Standard specifies the performance requirements and the corresponding test methods for all natural stone slabs used for external paving and road finishes. External paving use includes all pavements typical of road works, such as pedestrian and trafficked areas, out
26、door 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. This European Standard covers al
27、so characteristics that are of importance to the trade. This European standard does not cover natural stone slabs for floors and stairs in buildings. In these cases EN 12058 1 applies. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document an
