EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 3856-4 testing. ISO 3856-4 is an International Standard that specifies two methods for determining the cadmium content in paints and varnishes:
The purpose of this standard is to provide a reliable and accurate method for quantifying the soluble cadmium content in paints and varnishes, as cadmium is a toxic metal that can pose health risks if swallowed or inhaled.
The flame atomic absorption spectrometric method involves using a flame to vaporize the sample and then analyzing the resulting vapor using an atomic absorption spectrophotometer. This method provides a direct measurement of the amount of cadmium present in the sample.
The polarographic method involves using an electrode to measure the reducing current of cadmium ions in the sample. The reducing current is proportional to the amount of cadmium present in the sample, and the cadmium concentration is determined using a calibration curve.
Both methods require sample preparation by dissolving the paint or varnish in a suitable solvent. The standard specifies suitable solvents to be used for different types of paints and varnishes.
ISO 3856-4 also specifies requirements for the precision and accuracy of methods, as well as the calibration of instruments used for analysis. The standard provides guidelines for validation of methods, including determination of limit of detection and limit of quantification.
By following the procedures outlined in ISO 3856-4, paint and varnish manufacturers, testing laboratories and regulatory agencies can ensure that the cadmium content in paints and varnishes is measured accurately and reliably and that products containing excessive camium are not released into the environment.
