This European Standard specifies the essential requirements of sodium chloride (salt) for spreading on roads for winter maintenance and includes tests of these requirements. The requirements are specified for salt in crystallized form and for salt in solution (brine), which is delivered to the customer.

This European Standard specifies the essential requirements of calcium chloride and magnesium chloride for spreading on roads for winter 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.

This Technical Specification defines general specifications and performance criteria of other solid and liquid de-icing agents than chlorides of sodium, calcium and magnesium, hereinafter referred to products, for the use in winter service on roads and on roads for specific uses, with the exception of runways and parking areas of aircrafts. It establishes the test methods to control them. The products include inorganic and organic de-icing agents, and mixtures of chlorides of sodium, calcium, magnesium and potassium with organic and inorganic components which are intended for special properties like inhibition of corrosion, enhanced melting capacity or improved spreading pattern.
NOTE   This Technical Specification defines specifications and performance criteria and offers for each a variation in the form of classes of requirements. This does not mean that there are products likely to respond to all the classes and criteria of the standard. Therefore, when defining the demand the user needs to make sure prior the appropriateness of his choice and the availability of suitable products.

This European Standard specifies requirements for snow removal machines with rotating tools for winter application on traffic areas. It is valid for design and construction. It also includes the minimum requirement concerning contents of the operating instructions.
This European Standard applies to:
   snow blowers;
   snow cutters;
   snow cutter blowers;
and related products such as side blowers, side cutters, etc.
This European Standard does not apply for:
   requirements for registration and approval;
   vehicle manufacturer requirements;
   safety requirements.

This document is valid for snow ploughs designed to be fitted to winter maintenance vehicles on their front-mounting plates according to EN 15432 and also for side-mounted snow ploughs.
Requirements regarding the testing of override security systems and/or bump security systems of front-mounted or side-mounted snow ploughs for winter service are determined by this document. This document is meant to assess the demands made on snow ploughs operated in traffic.
The document is valid for:
-   single-side snow ploughs;
-   variable V-ploughs.
The following points are not standardized by this document:
-   V-shaped snow ploughs;
-   requirements for registration and approval;
-   requirements made by carrier vehicle manufacturers;
-   requirements on safety – these are dealt with in EN 13021.

This European Standard specifies the frequency, resolution and content of road weather observation and forecast products for a Road Weather Information Systems (RWIS).

This European Standard defines the "Road Weather Information Systems" (RWIS) concept for public roads and traffic surfaces.
This standard applies to the acquisition of data on weather-related road and environment conditions as well as their forecast.
This information is typically used for road maintenance and can serve other systems like traffic management, road users information, data models, etc.

This document is valid for snow ploughs designed to be fitted to winter maintenance vehicles, on their frontmounting
plates according to EN 15432 and also for side-mounted snow ploughs.
Demands on design and construction of front-mounted or side-mounted snow ploughs for winter service are
determined by this document. This document is meant to assess the demands made on snow ploughs
operated in traffic.
