OSB/1,OSB/2 ,OSB/3 ,OSB/4 Specification
It will soon be a legal requirement to demonstrate that OSB used in construction satisfies the requirements of the European Construction Products Directive. This legal requirement is written into national building regulations. Manufacturers shall demonstrate compliance with the legal requirements by showing that their OSB complies with the harmonised standard EN 13986 “Wood-based panels for use in construction – Characteristics, evaluation of conformity and marking”. This standard should be published before the end of 2001. It calls up EN 300 “Oriented Strand Boards (OSB) – Definitions, classification and specifications”, which will have to be used when specifying OSB.
Four grades of OSB are defined in EN 300 in terms of their mechanical performance and relative resistance to moisture. These are:
OSB/1 – General purpose boards and boards for interior fitments (including furniture) for use in dry conditions.
OSB/2 – Load-bearing boards for use in dry conditions.
OSB/3 – Load-bearing boards for use in humid conditions
OSB/4 – Heavy-duty load-bearing boards for use in humid conditions.如无特殊说明，文章均为本站原创，转载请注明出处。If there are no special instructions, the articles are original, if you want to use or reproduce, please indicate the original source www.plywoodinspection.com,If you find that our articles infringe on your copyrights and interests, please email us at email@example.com in time and we will delete it at the first time.
