(Main)Evaluation of conformity of fly ash for concrete - Guidelines for the application of EN 450-2
Evaluation of conformity of fly ash for concrete - Guidelines for the application of EN 450-2
This document specifies the scheme for the evaluation of conformity of fly ash according to EN 450-1:2005.
The document 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 450-2 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 defined 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.

Evaluation de la conformité de cendres volantes pour le béton — Guide pour l'application de l'EN 450-2
Ce document spécifie le système d’évaluation de la conformité des cendres volantes selon l’EN 450-1:2005.
Le document fournit des règles techniques applicables au contrôle de la production en centrale par le producteur, qui comprend les essais d’autocontrôle des échantillons. Il établit également des règles à suivre en cas de non-conformité, la procédure de certification de la conformité et les exigences relatives aux centres de distribution.
Ligne directrice
L’EN 450-2 traite de l’évaluation de la conformité des cendres volantes soumises à la certification. Elle traite en particulier de cas où des « essais complémentaires » du produit sont réalisés, comme c’est le cas du système d’attestation 1 + dans la Directive des produits de construction. Le produit auquel l’EN 450 2 s’applique est défini dans l’EN 450-1:2005 comme des cendres volantes pour la production de béton qui sont composées d’une poudre fine constituée principalement de particules vitreuses de forme sphérique issues de la combustion de charbon pulvérisé en présence ou non de co-combustibles, ayant des propriétés pouzzolaniques.

Foreword
This document (CEN/TR 15840:2009) has been prepared by Technical Committee CEN/TC 104 “Concrete
and related products”, the secretariat of which is held by DIN.
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 patent rights.
Introduction
The purpose of this Guidelines Document is to provide explanatory detail on points not fully
elaborated 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 not 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 procedures 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 the 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 ashes. 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 always 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 reproduced in full and is followed by guidance, which is provided only for those clauses where
clarification or elaboration is needed.
