BRIEF HISTORY
The IS0 Recommendation R 220, Method of Sampling Raw Cotton for Testing, was drawn
up by Technical Committee ISO/TC 38, Textiles, the Secretariat of which is held by the British
Standards Institution (B.S.I.).
Work on this question by the Technical Committee began in 1948 and led, in 1958, to the
adoption of a Draft IS0 Recommendation.

IS0 Recommendation R 220 December 1961
METHOD OF SAMPLING RAW COTTON FOR TESTING
1. SCOPE
1.1 A procedure is indicated for sampling raw cotton fibre for the purpose of determining
its various properties.
1.2 The various stages of sampling, intended to reduce the quantity of cotton to be handled
at different levels of the bulk to be tested, are described.
1.3 Special methods of sampling may be given in specifications or contracts for cotton, when
the nature of the materials or other circumstances make them desirable.
2. DEFINITIONS
2.1 Bulk source. One or more bales of cotton, for example:
(a) a bale,
(b) a group of bales of one variety,
(c) a group of bales of a particular grade,
(d) a group of bales from a given area,
(e) a group of bales of a particular blend or a mix at the mill.
2.2 Laboratory bulk sample. That portion of cotton taken from the bulk source in such a
way as to ensure its representative character and to provide a quantity small enough to
be handled with ease in the laboratory.
2.3 Laboratory test sample. That portion of cotton fibres taken from the laboratory bulk
sample in such a way as to ensure its representative character and to provide a quantity
small enough to be easily convertible into test specimens.
2.4 Test specimen. That portion of cotton fibres taken from the laboratory test sample which
is to be placed in the testing machine at one time in order to determine a particular property.
