BRIEF HISTORY
The IS0 Recommendation R 767, Fibre building boards - Determination of moisture content,
was drawn up by Technical Committee ISOlTC 89, Boards made from wood or other ligno-cellulosic
fibrous materials, the Secretariat of which is held by the Deutscher Normenausschuss (DNA).
Work on this question by the Technical Committee began in 1959 and led, in 1964, to the adop-
tion of a Draft Recommendation.
In October 1965, this Draft IS0 Recommendation (No. 841) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature,
by the following Member Bodies :
Argentina Hungary South Africa,
Australia India Rep. of
Austria Ireland Spain
Belgium Israel Sweden
Brazil Japan Switzerland
Canada Netherlands U.A.R.
Czechoslovakia New Zealand United Kingdom
Finland Poland U.S.S.R.
France Portugal Yugoslavia
Germany Romania
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in June 1968, to accept it as an IS0 RECOMMENDATION.

FIBRE BUILDING BOARDS
DETERMINATION OF MOISTURE CONTENT
1. SCOPE
This IS0 Recommendation describes a method of determining the moisture content of fibre building
boards, defined in IS0 Recommendation R .,* Fibre building boards - Definition - Classifica-
tion.
2. PRINCIPLE OF THE METHOD
To determine, by weighing, the loss of mass of each test piece between its state at the time of sampling
and its state after drying to constant mass and to relate this loss to the mass of the test piece after
drying.
