This European Standard shall be given the status of a national standard, either
21、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of an identical text or by endorsement, at the latest by May 2013, and conflicting national standards shall be withdrawn at the latest by August 2014.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 patent rights. CEN and/or CENEL
22、EC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1342:2001. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(
23、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 stones“. The change was made t
24、o 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. According to the CEN/CENELEC Internal Regulations, the national standards o

27、IHS-,-,-BS EN 1342:2012EN 1342:2012 (E) 5 1 Scope This European Standard specifies the performance requirements and the corresponding test methods for all natural stone setts used for external paving and road finishes. External paving use includes all pavements typical of road works, such as pedestr
28、ian 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 setts. Thi
29、s 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 dated references, only the edition cited applies. For u

41、 colour and place of origin as precisely as possible for example geo coordinates). 4.1.2 Alteration of physical properties of the natural stone If during production the natural stone setts have been subjected to a treatment process that physically alters the properties of the stone (for example chem

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 Gener
43、al The work dimensions of the setts shall be declared. Dimensions between faces shall be stated as a unitary nominal dimension or as a range of nominal minimum-maximum dimensions, e.g. (100 - 200) mm. Dimensions of each shall be measured in accordance with EN 13373. 4.2.2 Tolerances 4.2.2.1 Plan dim
44、ensions and thickness Plan dimensions and thickness of a sett shall be measured in accordance with EN 13373:2003, 5.2 and 5.3 and the deviations from the declared plan dimensions and thickness shall conform to tolerances given in Table 1. Different deviations may be declared for plan dimensions and
45、thickness. Unless stated otherwise, a consignment of setts shall be intended to be laid in rectilinear patterns and all setts within a consignment, when measured in accordance with EN 13373:2003, 5.4, shall conform with the tolerances from the plan and thickness dimensions described in Table 1.
