Summary

This European Standard specifies a method for measuring the pH value of bituminous emulsions.
It is applicable to anionic, cationic and non-ionic bitumen emulsions.
NOTE In certain circumstances, the pH value can provide an indication of the ionic character of a bitumen emulsion. However, this indication should be confirmed by a particle polarity test conforming to EN 1430 [1].
