Scope

This European Standard specifies the method for the determination of fly ash fineness by wet sieving on a 0,045 mm sieve (ISO 565). The European Standard specifies the reference procedure. If other methods are used it needs to be shown that they give results equivalent to those obtained by the reference method. In case of a dispute, only the reference method is used.
