19、 Bibliography 56 BS EN 12057:2015EN 12057:2015 (E) 4 Foreword This document (EN 12057:2015) has been prepared by Technical Committee CEN/TC 246 “Natural stones”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of
20、 an identical text or by endorsement, at the latest by September 2015, and conflicting national standards shall be withdrawn at the latest by December 2016. 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
21、not be held responsible for identifying any or all such patent rights. This document supersedes EN 12057:2004. EN 12057:2015 includes the following significant technical changes with respect to EN 12057:2004: durability, resistance to thermal and moisture cycling, skid resistance, direct airborne so
22、und insulation, thermal conductivity, release of dangerous substances added to requirements; sampling at the point of delivery added to the sampling; assessment and verification of constancy of performance added; Annex ZA substantially changed. This document has been prepared under a mandate given t

25、tural stone products Modular tiles Requirements; EN 12058, Natural stone products Slabs for floors and stairs Requirements; EN 12059, Natural stone products Dimensional stone work Requirements. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following c
26、ountries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
27、 Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 12057:2015EN 12057:2015 (E) 5 1 Scope This European Standard specifies requirements for flat modular tiles of natural stone which are made for internal (including enclosed public transpor
28、t premises) and/or external uses as floorings, stairs and wall and ceiling finishes. This European Standard does not cover mineral aggregates and artificial agglomerated stone material and does not cover installation. 2 Normative references The following documents, in whole or in part, are normative

43、The surface finishing of some types of stones may typically involve the use of patching, fillers or other similar products for natural holes, faults or cracks; this is to be considered as part of the normal processing. In such cases the type of treatment, as well as the type and nature of additional
44、 materials, shall be declared. 4.1.3.2 Requirements for surfaces after surface finishing Surfaces shall be worked to achieve the specified finish and shall have a regular appearance as a result of the finishing process (e.g. making reference to samples, see 4.2.3). For definitions of surface finishe
45、s, see EN 12670. 4.2 Physical and mechanical characteristics 4.2.1 General Whenever stone processing is likely to change the characteristics of the raw material (e.g. as a consequence of the type of processing or because the use of patching, fillers or other similar products for natural holes, fault
46、s, cracks and similar), then this has to be considered when determining the characteristics requested by this document. The following characteristics shall be declared where requested by this document or with reference to the use conditions. BS EN 12057:2015EN 12057:2015 (E) 8 4.2.2 Denomination The
