Weighed-in concentration

The weighed-in concentration (mg/L) is given for information only.  It is published three days after the distribution closes and can be used to give a guide to individual laboratory performance. ALTM values (mg/L) and statistics are published as soon as they are available.

Target

The ALTM is used as the target concentration by the Scheme for determination of laboratory performance for all analytes


The weighed-in values are also available by telephone (recorded message) on INT+UK+117 9505050 Extension 2269
