ועדה 10601EN 197-1:2011 (E)9 Conformity criteria9.1 General requirementsConformity of the products to this standard shall be continually evaluated on the basis of testing of spot samples. Theproperties, test methods and the minimum testing frequencies for the autocontrol testing by the manufacturer arespecified in Table 6. Concerning testing frequencies for cement not being dispatched continuously and other details, seeEN 197-2. Alternative test methods could be used provided that they have been validated in accordance with theappropriate provisions in the cited standards of the reference test methods. In the event of a dispute, only the referencemethods are used.NOTE 1NOTE 2EN 197-2.This standard does not deal with acceptance inspection at delivery.For certification of conformity by a notified body, conformity of cement with this standard is evaluated in accordance withThe compliance of the common cements with the requirements of this standard and with the stated values (includingclasses) shall be demonstrated by:⎯ initial type testing,⎯ factory production control by the manufacturer, including product assessment.22
