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. (a)

    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. (b)

    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. (i)

      solutions with an acidity < pH 1;

    2. (ii)

      solutions with an alkalinity > pH 13;

    3. (iii)

      corrosive solutions containing halogen gas;

  3. (c)

    measurements of conductivities above 100 mS/m that must be performed with portable instruments.

Expires on 31 December 2018.
