This document, part of EN 13130, specifies an analytical procedure for the determination of residual epichlorohydrin in coatings.
The method is appropriate for the quantitative determination of epichlorohydrin in the analyte concentration range of 5 ng/ml to 80 ng/ml of extract. In general this allows for the detection of epichlorohydrin at the level of 1 mg/kg of polymer or in the case of coatings, where the amount of polymer cannot be determined, detection of 1 µg epichlorohydrin per square decimetre of coating is feasible.
In order to obtain reliable and reproducible results, it is essential that the method described in this part of EN 13130 is followed as closely as possible.
