Annex A forms an integral part of this part of IS0 The laboratory bias is further considered in IS0 It was therefore decided to discard the results from laboratory 10 completely; it should be the object of special attention, and the matter should be resolved. The work of preparing International Standards is normally carried out through IS0 technical committees.
