"Technical Report 16-AMD-T-6-81-VC." Includes bibliographical references (pages 128-130). "Specification statements (precision, accuracy and detection limit) derived from round robin interlaboratory investigation on an analytical method are indexes of the reliability, credibility and limitation of the routine data generated, and thus form an integral and essential part of the measurement process. Since methods in the Water Quality Branch Analytical Methods Manual do not yet possess such statements, the need to generate them is urgent otherwise NAQUADAT data may not be interpreted with demonstrated levels of confidence. This report is the first (Phase I) of a series which fulfills this need and specifies interlaboratory statements of detection limit, precision and accuracy on all existing methods and the future ones used by the Water Quality Branch laboratories across Canada -Moncton, Longueuil, Burlington, Calgary and Vancouver"--Abstract.
