Risk Note B

Some substances (acids, bases, etc.) are placed on the market in aqueous solutions at various concentrations and therefore require different labelling since the hazards vary at different concentrations.

In this case the manufacturer or any other person who markets such a substance must state the percentage concentration of the solution on the label.

Unless otherwise stated, it is assumed that the percentage concentration is calculated on a weight/weight basis.

The use of additional data (e.g. specific gravity, degrees Baum~) or descriptive phrases (e.g. fuming or glacial) is permissible.
