Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 616 was prepared by Technical Committee
lSO/TC 27, Solid mineral fuels, Subcommittee SC 3, Coke.
This second edition cancels and replaces the first edition (ISO 616:1977),

Introduction
The shatter index of coke tan be determined for one test sieve or for each
of a number of test sieves of different sizes of holes (e.g. 80 mm and
40 mm). The higher the shatter index, the greater the resistance of the
coke to breakage into pieces which are smaller than the stated size.
The mean size of the coke before and after the shatter test may also be
determined to give additional information about the strength of the Coke.
