ABSTRACT

The European Cement Association, Cembureau, had already taken an initiative in respect of assessment of conformity, and had produced a draft scheme for certification of European cements. This scheme document was taken by Working Group 13 and developed over the subsequent two years. The final draft of the document was awarded the status of a European prestandard at the CEN/TC51 meeting of June 1994 and became: ENV 197-2 “Cement-Conformity evaluation”. This prestandard forms the subject of this paper. It should also be noted, that, in May 1992, CEN/TC51 WG13 was further charged with the task of revising clause 9, conformity criteria, of ENV 197-1:1992, in order to make it fully complimentary to the certification document. Opportunity was also taken to simplify the clause and to remove redundant terminology. Thus, standardisation and certification have been brought together to form a complete and coherent scheme. The eventual EN 197-1 will give the conformity criteria and EN 197-2 will detail the procedures for evaluation of conformity.
