PAPER AND BOARD - DETERMINATION OF WATER ABSORPTIVENESS - COBB METHOD (ISO 535 : 1991, IDT)
This Malaysian Standard was developed by the Technical Committee on Pulp, Paper and
Board under the authority of the Chemical and Materials Industry Standards Committee.
This Malaysian Standard is identical with ISO 535: 1991, Paper and board — Determination of
water absorptiveness — Cobb method, published by the International Organization for
Standardization (ISO). The text of the International Standard is recommended for publication
as a Malaysian Standard without deviation. However, for the purpose of this Malaysian
Standard, the following apply:
a) the water absorption apparatus which is referred to in Clause 6, is inserted as Figure Al.
in Annex A for information purposes;
b) in the source text, ‘This International Standard” should read “this Malaysian Standard”;
and
c) the comma which is used as a decimal sign (if any), to read as a full point.
References to International Standards should be replaced by equivalent Malaysian Standards
as follows:
Referenced International Standards Corresponding Malaysian Standards
ISO 186 :1985, Paper and board —
Sampling to determine average
quality.
ISO 187 : 1990, Paper, board and
pulps Standard atmosphere for
conditioning and testing and
procedure for monitoring the
atmosphere and conditioning of
samples.
ISO 5269-1 : 1979, Pulps —
Preparation of laboratory sheets for
physical testing — Part 1
Conventional sheet-former method
MS ISO 186 : ~, Paper and board —
Sampling to determine average quality.
MS ISO 187 : 2001, Paper, board and
puips — Standard atmosphere for
conditioning and testing and procedure
for monitoring the atmosphere and
conditioning of samples.
MS ISO 5269-1 : ~ Pulps —
Preparation of laboratory sheets for
physical testing — Part 1: Conventional
sheet-former method.
This Malaysian Standard cancels and replaces MS 9 : 1989, ‘Method of sampling to
determine average quality of paper and board (First Revision)’.
Compliance with a Malaysian Standard does not of itself confer immunity from legal
obligations.
NOTE. POT on the front cover indicates an identical standard i.e. a standard where the technical content, structure,
wording and presentation of a Malaysian Standard is exactly the same as in an International Standard or is identical
in technical content and it may contain the minimal editorial changes specified in clause 4.2 of ISO/IEC Guide 21.
