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. Each 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO 6888-2:1999 was prepared by Technical Committee ISO/TC 34, Food products,
Subcommittee SC 9, Microbiology.

Replace part of the second paragraph by the following text.
“Both parts of ISO 6888 are given equivalent status. Nevertheless, it is recommended to use the procedure
described in ISO 6888-2 for the foods (such as cheeses made from raw milk and certain raw meat products)

11 Precision
11.1 General
The precision of quantitative methods can be expressed in terms of repeatability and reproducibility, as
defined in ISO 5725-2. However, the method of calculation used in ISO 5725-2, based on the mean, is not
always appropriate for microbiological analyses, which do not always show a normal (Gaussian) distribution.
Therefore ISO 16140, which has been especially developed for microbiological methods and which uses
robust estimators for calculating repeatability and reproducibility, has been followed. These statistics have the
advanta
