European Standards


The European standards committee CEN/TC112, through its working groups concerned with fibreboard and general test methods for wood based sheet materials, has produced a large number of standards concerned with the classification of fibreboards into different types covering soft board, medium board, hardboard and medium density fibreboard, test methods to assess the properties of these materials and specifications of performance for different grades of each type, based on results obtained in these tests.

Some National standards, in Italy, Spain and the United Kingdom in particular, specify methods of test and performance requirements for MDF but as MDF is a relatively new product in standard terms, it has not been subject to national standardisation to the same extent as particleboard. The standards relating to MDF emanating from CEN/TC112 provide the most comprehensive set of test method standards and performance specifications in Europe. The test methods are already widely used by MDF manufacturers for quality control purposes. The MDF specification standard EN 622-5 replaces National standards for MDF.
