Introduction

This European Standard has been written as the system for the evaluation of conformity of aggregates. It is designed to be used in conjunction with the aggregate product standards: EN 12620, EN 13043, EN 13139, EN 13242, EN 13383‑1 and EN 13450 and is called up by these standards. This European Standard and the corresponding product standards have been written under the Construction Products Directive (CPD).

Evaluation of conformity comprises initial type testing (ITT) and factory production control (FPC).

This standard has been compiled from the ITT and FPC clauses, annexes and tables previously found in the aggregate product standards. A new, separate Evaluation of Conformity standard is currently in preparation, which will provide more detailed ITT procedures and clear, detailed requirements for product conformity (e.g. statistical conformity criteria, number of samples, tolerances, time limits of validity etc).

The initial type testing and factory production control procedures are designed to be applied to European Standards for aggregates. When the appropriate "conformity" clauses are applied, it forms part of the system for attestation of conformity as required by the Construction Products Directive. It provides the minimum level of ITT and FPC for CE Marking.

The testing procedures, using the reference test methods, have the function of providing assurance that a particular aggregate product complies with each of the selected specified requirements in the product standard. The type testing procedure is designed to be applied to all harmonised elements of European Harmonised Standards for aggregates. The system can also be extended to non-harmonised elements.

The factory production control system describes control of the sourcing and processing of the aggregate combined with routine sampling and testing to provide ongoing assurance that the aggregates product continues to conform to those properties determined through ITT. Testing within FPC may use either the standard reference tests called up by the aggregate product standards or other test procedures which have been shown to correlate with those tests.

For commercial and/or contractual reasons, the manufacturer can choose to perform more testing and inspection than the minimum specified.
