Introduction
De-icing agents are important for the winter maintenance of roads and other traffic areas. They can
prevent or eliminate slippery conditions. The Technical Specification describes the requirements for de-
icing agents with different properties from de-icing agents according EN 16811-1 and EN 16811-2, and
which are used for specific services on roads. The testing methods are included in the Technical
Specification.
The multitude of products which can be used in winter maintenance - liquid or solid, natural or
industrial produced substances – requires the defining of performance criteria with which the products
have to comply.
These criteria are used to assess the usability of the de-icing products while taking into consideration all
aspects of the safety of the road user, of the protection of the environment and of the road conditions.
