適用范圍：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 testingof samples. It also provides rules for actions to be followed in the event of non-conformity, the procedure forthe certification of conformity and requirements for dispatching centres.GuidanceEN 450-2 deals with the evaluation of conformity of fly ash submitted for certification. It deals in particularwith 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 inEN 450-1:2005 as fly ash for the production of concrete which consists of a fine powder of mainlyspherical, glassy particles, derived from burning of pulverised coal, with or without co-combustionmaterials, which has pozzolanic properties.
