BS EN 16811-2:2016EN 16811-2:2016 (E) 5 Introduction De-icing agents are important for the winter maintenance of ro
25、ads. They can prevent and, in addition to it, eliminate slippery conditions. The standard describes 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. Th
26、e aim of this standard is an easy description of the product specifications for tenders and other purchasing procedures. BS EN 16811-2:2016EN 16811-2:2016 (E) 6 1 Scope This European Standard specifies the essential requirements of calcium chloride and magnesium chloride for spreading on roads for w
27、inter maintenance and includes tests of these requirements. The requirements are specified for calcium chloride and magnesium chloride in solid form and in water solution, which is delivered to the customer. 2 Normative references The following documents, in whole or in part, are normatively referen
