DIN 53902-2 Surfactants - Test for Determination of Foaming Power

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DIN 53902-2 testing. This standard specifies a method for determining the foaming power of surfactants and products made from them, especially bath additives, regardless of their ionogenicity.

When developing new products, it is essential to distinguish precisely the features. For this reason, the foaming behavior of liquids should be tested especially for the application. This is done in two steps. First, foam must be produced, and secondly, the foam height must be measured.

The foam height is determined visually by the user at regular intervals by means of a container with a measuring scale. This requires great care because the foam surface is not smooth and as a result subjective errors are not eliminated.

Foam height is measured with a light source and a light sensor. The foam refracts the emitted light and therefore shadows the light sensor. The measurement result may be inaccurate due to contamination of the container. The unevenness of the foam height is not recorded.

There is a disadvantage in using these methods to test foam, either that the measurement results are not reproducible or that subjective effects affect the results.
