Tests which have previously been performed in accordance with the provisions of this standard (same product, same characteristic, test method, sampling procedure, etc.) may be taken into account for the purpose of demonstrating satisfactory initial type testing. Initial type tests shall also be carried out on existing products after any change in raw materials or manufacturing procedures that can modify the declared values of the characteristics or application properties. In these cases the appropriate initial type testing to be carried out are those for the characteristics and properties that can be affected and need confirmation; any new property or properties arising from a change of formulation or manufacturing procedure shall be tested and the results reported. The initial type testing shall be performed as listed in !Table 5". !Only one ITT is required where different manufacturing units are producing the same product, for the same manufacturer, using the same materials (having the same performance) and documented production and process control. Where components (e.g. cement) are used whose characteristics have already been determined by the component supplier on the basis of conformity with other product standards, these characteristics need not be re-assessed to demonstrate compliance with the European Standard. Retesting due to a new method of production or product modification, or change of supplier of components, shall only be performed if one or more of the stated performance characteristics will be downgraded, i.e. the mix design becomes dissimilar. A manufacturer may, however, always retest if he wishes to declare improved performance." SIST EN 12004:2007+A1:2012
