EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 3856-6 testing. ISO 3856-6 is a standard that provides guidelines for the determination of the total chromium content in the liquid portion of paints and varnishes. The standard specifies a flame atomic absorption spectrometric method for this purpose.
Chromium is a metal widely used in paint and varnish production. While some types of chromium are essential for human health, others, particularly hexavalent chromium, can be toxic. Therefore, it is important to measure the total chromium content in paints and varnishes to ensure their safety.
The flame atomic absorption spectrometric method involves burning a small amount of the liquid portion of the paint in a flame that evaporates the chromium and other elements present. The evaporated elements are then excited by a beam of light from a hollow cathode lamp, and the amount of light absorbed by the chromium atoms is measured by a detector. The amount of absorption is proportional to the amount of chromium present in the sample and can be used to calculate the total chromium content of the paint.
The ISO 3856-6 standard provides detailed instructions for performing the flame atomic absorption spectrometric method, including equipment, reagents, sample preparation, and calculation of results. The standard also specifies limits for the maximum total chromium content allowed in paints and varnishes.
Overall, ISO 3856-6 is an important standard for ensuring the safety and quality of paints and varnishes and protecting the health of workers and consumers who may come into contact with these products.
