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.
1 Scope
This document specifies the essential requirements of stationary systems for production of brines for
winter road maintenance and includes tests of these requirements. Installation boundary: chloride and
water inlet to the saturator, brine outlet to the spreading machine. Within the scope are materials, brine
storage and brine loading/unloading equipment also. Mobile systems for production of brines in situ are
not content of this document.
The following points are not covered by this document:
— System and construction requirements;
— Requirements according to national and European legislations.
