Replaces the approved standard NF EN 196-1 of April 2006. Correspondence The European standard EN 196-1:2016 has the status of French standard. Summary This document describes the method for the determination of the pressive andoptionally the flexural strength of cement mortar.The method applies to mon cements and to other cements and materials for which the standards call up this method.It may not apply to other cement types that have for example a very short initial setting time. The method is used for assessing whether the pressive strength of the cement is in conformity with its specification.It is also used for validation testing of a CEN standard sand EN 196 1 or alternative paction equipment.
