ANNEX
In Annex IV to Directive 2011/65/EU the following point 37 is added:
37.

Lead in platinized platinum electrodes used for conductivity measurements where at least one of the following conditions applies:
1. wide-range measurements with a conductivity range covering more than 1 order of magnitude (e.g. range between 0,1 mS/m and 5 mS/m) in laboratory applications for unknown concentrations;
2. measurements of solutions where an accuracy of +/– 1 % of the sample range and where high corrosion resistance of the electrode are required for any of the following:
  1. solutions with an acidity < pH 1;
  2. solutions with an alkalinity > pH 13;
  3. corrosive solutions containing halogen gas;
3. measurements of conductivities above 100 mS/m that must be performed with portable instruments.
Expires on 31 December 2018.
