Fire protection is becoming increasingly important in all areas today. As Europe did not have any uniform regulations until the EN 45545 was ratified by CEN, each country had its own national directives as well as a multitude of different rules that were established by manufacturers, certification and test laboratories, and public authorities. The harmonisation of these rules and regulations now binding for all European countries has led to optimised processes in production, marketing and sales, opened a wider and more versatile marketplace (throughout Europe) for component suppliers, and provided a more convenient exchange of best practice concepts among manufacturers. Furthermore, it ensures familiarity with the requirements and reutilisation of information and has led to eliminating trade barriers with a view to increasing interoperability and creating a common (European) market.
