23、245:2001, the following changes have been made: Guidelines harmonized with EN 197-2:2014 and standard text of EN 197-2:2014 included.

PD CEN/TR 14245:2014CEN/TR 14245:2014 (E) 5 Introduction to this Guidelines Document Purpose The purpose of this Guidelines Document is to provide explanatory detail on points not fully elaborated in EN 197-2. It is intended for use by manufacturers and b

26、y product certification bodies involved in the certification of cement following EN 197-2, in particular for the issuing of an EC certificate of constancy of performance. This document does not deal with the necessary internal procedures that the product certification bodies will have. It is an obje

27、ctive of this Guidelines Document that its use will assist in the establishment of equivalent procedures for certification of cement. It is expected that, following this document, traditional good procedures and practices that may be different can continue to be used, provided that they are not in c

28、ontradiction with EN 197-2 and the relevant product specification standard. Such existing good procedures and practices, applied in conjunction with these Guidelines, are not considered to be an impediment to the achievement of the uniform level of certification throughout Europe, and by different p

29、roduct certification bodies, that is expected from the application of EN 197-2 together with these Guidelines. This Guidelines Document is based on existing situations for production, evaluation of conformity and certification of cements. It may happen that product certification bodies be confronted

30、 by a situation different to those included in this document. In such a case, specific procedures should be elaborated on a case by case situation and be approved and fully recorded by the product certification body. These specific procedures should always fulfil the requirements of EN 197-1 and EN

31、197-2 and lead to the same level of confidence in product conformity that would be achieved by application of this Guidelines Document. Arrangement The clause numbering system of EN 197-2 is followed. The text of each of the clauses of the European Standard is reproduced in full and is followed by g

32、uidance, which is provided only for those clauses where clarification or elaboration is needed.

34、rd This document (EN 197-2:2014) has been prepared by Technical Committee CEN/TC 51 “Cement and building limes”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the late

35、st by July 2014, and conflicting national standards shall be withdrawn at the latest by July 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 CENELEC shall not be held responsible for identifying any or all such pa

36、tent rights. This document supersedes EN 197-2:2000. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. Compared to the version EN 197-2:2000, the following major changes have been made in this document: use of the termino

37、logy given by the Construction Products Regulation (Regulation (EU) No 305/2011) and comparison with the earlier terminology according to the Construction Products Directive (Directive 89/106/EEC) (Annex C); link between this European Standard and Annexes ZA of European Standards covering cements; g

38、uidance concerning the uncertainty of measurements in the evaluation of test results; numerical criteria for the evaluation procedure for calcium aluminate cement conforming to EN 14647, (Annex A); figure describing the procedure for certification of constancy of performance of cement in a new facto

39、ry or of a new type of cement in an existing factory (Annex B). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Esto

40、nia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. PD CEN/TR 14245:2014CEN

41、/TR 14245:2014 (E) 7 1 Scope This European Standard specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements to their corresponding product specification standards, including certification of constancy of performance by a product certification body. The

42、standard provides technical rules for factory production control by the manufacturer, including autocontrol testing of samples, and for the tasks of the product certification body. It also provides rules for actions to be followed in the event of non-conformity, the procedure for the AVCP and requir

43、ements for dispatching centres. In this European Standard, the word “cement” is used to refer both to common cements as defined in EN 197-1 and to other cements and binders for which the relevant product specification standard makes reference to this European Standard and which are submitted for cer

44、tification. Such a cement is produced at a given factory and belongs to a particular type and a particular strength class, as defined and specified in the relevant product specification standard. The guidelines given in the Technical Report CEN/TR 14245 11)should be used for the application of this

45、European Standard. This European Standard should be linked with Annexes ZA of European Standards covering cements and binders, i.e. EN 197-1, EN 14216, EN 14647, EN 413-1, EN 15743, in particular for the assignments of tasks to the manufacturer and to the product certification body. NOTE The reason

46、for having drafted this separate document is that the provisions it includes are applicable to different products covered by different European Standards. Guidance EN 197-2 deals with the evaluation of conformity of cements and binders that are submitted for certification. It deals in particular wit

47、h cases where “further testing” of the product is undertaken, as is the case for attestation system 1+ under the Construction Products Regulation. The products for which EN 197-2 is applicable are: the common cement products and the low heat cements and the sulfate resisting cements, refer to EN 197

48、-1, the very low heat special cements, refer to EN 14216, the supersulfated cements, refer to EN 15743, the calcium aluminate cements, refer to EN 14647, and the masonry cements, refer to EN 413-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in thi

49、s document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
