Division 3.2 Specific procedure in case of examination by visual inspection or by microscopy or in cases where the whole aggregate sample is homogenisedF1

In case of an examination by visual inspection (without making use of microscope), the whole laboratory sample is used for examination.

In case of a microscopic examination, the laboratory may reduce the aggregate sample, or further reduce the reduced sample. The final samples for defence and eventually reference purposes are taken following a procedure equivalent to the procedure followed for the final sample for enforcement.

In case the whole aggregate sample is homogenized, the final samples are taken from the homogenized aggregate sample.
