CEN/TC 289/WG 6 - Test methods for tannery chemicals

This document specifies a method for determining the total content (solvent extractable) of the following bisphenols in chemicals for the leather tanning industry:
—     bisphenol A;
—     bisphenol AF;
—     bisphenol B;
—     bisphenol F;
—     bisphenol S.
This method requires the use of liquid chromatography (LC) with either a single quadrupole mass spectrometer (MS), a triple quadrupole mass spectrometer (MS/MS), an ultraviolet (UV) detector, a diode array detector (DAD) or a fluorescence detector (FLD) to identify and quantify the bisphenols.
NOTE 1        This method can also be used for other bisphenols if they are validated by the laboratory.
NOTE 2        Bisphenol S cannot be detected with FLD.

This document specifies a method for determining the total content of the following cyclosiloxanes in chemicals for the leather tanning industry:
—   octamethylcyclotetrasiloxane (D4);
—   decamethylcyclopentasiloxane (D5);
—   dodecamethylcyclohexasiloxane (D6);
This method requires the use of Gas chromatography (GC) equipped with a single quadrupole mass spectrometer (MS) to identify and quantify the cyclosiloxanes
