DIN EN 16811-2:2016-10EN 16811-2:2016 (E) 5 Introduction De-icing agents are important for the winter maintenance of roads. They can prevent and, in addition to it, eliminate slippery conditions. The standard descri
28、bes the requirements for de-icing agents and their testing methods. The requirements are different for using, storage and type of distribution (spreading and spraying). These need different properties. The aim of this standard is an easy description of the product specifications for tenders and othe
