Introduction
De-icing agents in solid and liquid form are important for the winter maintenance of roads. They can
prevent respectively eliminate slippery road conditions. Brines are used for anti-icing (preventive winter
maintenance) and de-icing (curative winter maintenance) in pure form or in mixture with solid sodium
chloride as pre-wetted salt.
The document describes the requirements for brine production systems and their testing methods.
The aim of this document is an easy description of the product specifications for tenders and other
purchasing procedures.
