20、 an identical text or by endorsement, at the latest by September 2015, and conflicting national standards shall be withdrawn at the latest by December 2016.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.

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
