National foreword

Board for Building and Civil Engineering and is the English language version of
EN 120 : 1992 Wood-based panelsÐ Determination of formaldehyde contentÐ
Extraction method called the perforator method, published by the European
Committee for Standardization (CEN).
EN 120 was produced as a result of international discussion in which the UK took an
active part.
The principle of this method is technically equivalent to clause 15 of BS 1142 : 1989
Specification for fibre building boards and to clause 22 of BS 5669 Particleboard :
Part 1 : 1989 Methods of sampling, conditioning and test, both of which will be
withdrawn in due course.
A British Standard does not purport to include all the necessary provisions of a
contract. Users of British Standards are responsible for their correct application.
Compliance with a British Standard does not of itself confer immunity
from legal obligations.
