Attention is drawn to the possibility that some of the elements of this document may
19、 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 1342:2001. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, an
20、d 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) Where possible the requirements refer to separate test methods prepared by C
21、EN/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 declared values are now lower expected values.

BS EN 1342:2012EN 1342:2012 (E) 5 1 Scope This European Standard specifies the performance requirements and the
24、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 pedestrian and trafficked areas, outdoor squares and similar to be used in an outdoor condition that are subject to the weather
25、ing 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. This European Standard also covers characteristics that are of importance to the trade. 2 Normative references The followin

36、1 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). 4.1.2 Alteration of physical properties of the natural stone If during produc
37、tion the natural stone setts have been subjected to a treatment process that physically alters the properties of the stone (for example chemical treatment, patching, or filling or other similar products for natural holes, faults or cracks) then the use of such a treatment shall be stated. In additio
38、n, specimens for testing shall be representative of the product and any processes that the stone is subjected to. 4.2 Dimensions 4.2.1 General 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-
39、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 dimensions 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 declar
40、ed plan dimensions and thickness shall conform to tolerances given in Table 1. Different deviations may be declared for plan dimensions and thickness. Unless stated otherwise, a consignment of setts shall be intended to be laid in rectilinear patterns and all setts within a consignment, when measure
41、d in accordance with EN 13373:2003, 5.4, shall conform with the tolerances from the plan and thickness dimensions described in Table 1.

43、 bigger, smaller and trapezoidal setts not varying from the dimensions allowed by the stated tolerance by more than 10 %. When dimensions between faces are declared as a range of nominal minimum maximum thickness, the deviation shall be declared on the limits of the range. This is particularly appli
44、cable to hewn setts. In all cases the thickness of the setts shall be observed. 4.2.2.2 Undercut of sides When measured in accordance with EN 13373:2003, 5.5, deviations of the undercut of a side shall not exceed the tolerances given in Table 2 with respect to the perpendicularity of the upper face

48、l conditions When the setts are intended to be used in areas subjected to freeze and thaw freeze-thaw requirements, the freeze/thaw resistance shall be determined using the test method in EN 12371. The results shall be expressed and declared as the mean compressive strength before and after 56 cycle
49、s of freeze/thaw (technological test). The frost damage, which a natural stone may suffer when installed, depends on the climatic conditions of the place of use, the relative position in the works (which determines the degree of saturation) and the predicted service life of the works. This number of cycles is appropriate to a specific project and may help to provide guidance for the interpretati
