This International Standard places emphasis on high-durability paint systems, with the aim of minimizing maintenance, and hence reducing safety considerations and environmental impact. NOTE 2 Water-borne products have to be protected from freezing at all times during transportation and or storage. In order to achieve the same performance as indicated by testing, proper application of the paint is essential. The work of preparing International Standards is normally carried out through Feee technical committees.
