Attention is drawn to the possibility that some of the elements of this

PD CEN/TR 15840:2009 CEN/TR 15840:2009 (E) 5 Introduction The purpose of this Guidelines Document is to provide explanatory detail on points not fully elabora

18、ted in EN 450-2:2005 “Fly ash for concrete Part 2: Conformity evaluation“. It is intended for use by producers and by certification bodies involved in the certification of fly ash following EN 450-1 and EN 450-2, in particular for the issuing of an EC Certificate of Conformity. This document does no

19、t deal with the necessary internal procedures that the certification bodies will have. It is an objective of this Guidelines Document that its use will assist in the establishment of equivalent procedures for certification of fly ash. It is expected that, following this document, traditional good pr

20、ocedures and practices that may be different can continue to be used, provided that they are not in contradiction with EN 450-1:2005 and EN 450-2. Such existing good procedures and practices, applied in conjunction with these Guidelines, are not considered to be an impediment to the achievement of t

21、he uniform level of certification throughout Europe, and by different certification bodies that is expected from the application of EN 450-2 together with these Guidelines. This Guidelines Document is based on existing situations for production, evaluation of conformity and certification of fly ashe

22、s. It may happen that certification bodies be confronted 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 Certification Body. These specific procedures should al

23、ways fulfil the requirements of EN 450-1:2005 and EN 450-2 and lead to the same level of confidence in product conformity that would be achieved by application of this Guidelines Document. The clause numbering system of EN 450-2 is followed. The text of each of the clauses of the Standard is reprodu

24、ced in full and is followed by guidance, which is provided only for those clauses where clarification or elaboration is needed. PD CEN/TR 15840:2009 CEN/TR 15840:2009 (E) 6 1 Scope This document specifies the scheme for the evaluation of conformity of fly ash according to EN 450-1:2005. The document

25、 provides technical rules for the production control by the producer, including autocontrol testing of samples. It also provides rules for actions to be followed in the event of non-conformity, the procedure for the certification of conformity and requirements for dispatching centres. Guidance EN 45

26、0-2 deals with the evaluation of conformity of fly ash submitted for certification. It deals in particular with cases where “further testing” of the product is undertaken, as is the case for attestation system 1 + under the Construction Products Directive. The product for which EN 450-2 applies is d

27、efined in EN 450-1:2005 as fly ash for the production of concrete which consists of a fine powder of mainly spherical, glassy particles, derived from burning of pulverised coal, with or without co-combustion materials, which has pozzolanic properties. 2 Normative references The following referenced

31、icating that adequate confidence is provided that fly ash is in conformity with EN 450-1:2005 Guidance The term “certificate of conformity” refers to certificates of conformity issued by a certification body under the rules of EN 450-2. This includes an EC Certificate of Conformity issued in relatio

32、n to the CPD. 3.1.2 conformity mark protected mark applied on the basis of the certificate of conformity (see 3.1.1) PD CEN/TR 15840:2009 CEN/TR 15840:2009 (E) 7 Guidance The term “protected mark” includes registered mark, regulated mark and CE marking. 3.1.3 certified fly ash fly ash for which a ce

33、rtificate of conformity has been issued 3.1.4 initial period immediate period after the first issuing of the certificate of conformity for a fly ash 3.1.5 certification body impartial body, governmental or non-governmental, possessing the necessary competence and responsibility to carry out conformi

34、ty certification according to given rules of procedure and management 3.1.6 production control permanent internal control of fly ash production exercised by the producer consisting of internal quality control and autocontrol testing 3.1.7 production plant facility used by a producer for the producti

35、on of fly ash: a) power plant with one (several) boiler(s), b) processing plant, for example for the classification, selection, sieving, drying, blending, grinding and/or carbon reduction of fly ash(es). In the production plant, equipment has to be used which is suitable for production of fly ash in

36、cluding the necessary silo capacity for the storage and dispatch of the fly ash produced, and equipment to test, evaluate and control the fly ash production. This equipment and the production control applied allow the control of production with sufficient accuracy to ensure that the requirements of

37、EN 450-1:2005 are met Guidance Two categories of production plant are recognised: traditional power station facility where fly ash is produced as part of the production of electricity; processing plants that may or may not be on a power station facility, where ashes are altered in some manner. 3.1.8

38、 new production plant production plant which is not already producing fly ash certified under this scheme 3.1.9 existing production plant production plant which is already producing fly ash certified under this scheme PD CEN/TR 15840:2009 CEN/TR 15840:2009 (E) 8 3.1.10 depot bulk fly ash handling fa

39、cility (not located at the production plant) used for the dispatch of fly ash (whether in bulk or bagged) after transfer or storage, where the producer has full responsibility for all aspects of the quality of the fly ash Guidance It is important to point out the difference between a depot and a dis

40、patching centre. The difference consists essentially of the linkage to the production plant and the responsibility for the quality of the fly ash. In the case of a depot, the facility is strictly linked to the production plant and is included in the production plant Works quality manual. The produce

41、r has full responsibility for the quality of the fly ash released from the depot. In a dispatching centre, in contrast, the facility is not at all linked to the production plant and it is an intermediary (an entity taking certified fly ash, acting independently and operating between the producer and

42、 a subsequent customer) who has full responsibility for the quality of the fly ash dispatched. A dispatching centre, being independent from the production plant cannot be included in a Works quality manual, but it has to ensure, using appropriate rules, that the quality of an already certified fly a

43、sh does not undergo any change. Depots are included in the Works quality manual. An entity other than the producer may own and operate the depot but it does this on behalf of and under the strict quality management responsibility of the producer. 3.1.11 dispatching centre bulk fly ash handling facil

44、ity (not located at the production plant) used for the dispatch of fly ash after transfer or storage where an intermediary has full responsibility for all aspects of the quality of the fly ash Guidance See guidance under 3.1.10 and 9.1. 3.1.12 intermediary natural or legal person who takes from the

45、producer fly ash certified according to EN 450-2 and bearing the conformity mark, who undertakes full responsibility for maintaining in a dispatching centre all aspects of the quality of the fly ash and who supplies the fly ash onwards to a further natural or legal person 3.1.13 confirmation autocon

NOTE The requirements of EN 450-2 as regards the production control take account of those clauses of EN ISO 9001 6 which are relevant to the production, process control and testing of fly ash.
