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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO’s adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

Preparation, production, storage and performance testing
of culture media
AMENDMENT 1
Introduction
Add the following text as the last paragraph:

When specific standards are revised and new standards developed, they will include a paragraph for

performance testing of the culture media used in the standard.
Scope
Replace the last paragraph with the following:

This document also sets criteria and describes methods for the performance testing of culture media.

This document is applicable to end-users of ready-to-use media and to producers such as

— commercial bodies producing and/or distributing ready-to-use or semi-finished reconstituted or

dehydrated media,
— non-commercial bodies supplying media to third parties, and
— microbiological laboratories preparing culture media for their own use.
3.2.6, electivity of culture medium
Replace the definition with the following:

demonstration, under defined conditions, that non-target organisms, if able to grow on the medium, do

not show the same visual characteristics as target microorganisms
4.3.1 General
Add the following text as the third paragraph:

When a formula indicates an ingredient in hydrated form (e.g. Na HPO ·12H O for BPW in ISO 6887-1)

2 4 2

it can be replaced by an anhydrous or hydrated ingredient with a different number of water molecules,

as long as the final quantity of the ingredient takes account of this difference by calculation of the

molar mass.

4.3.8.1 General
Replace the last sentence with the following:

In all cases, make reference to the appropriate International Standard or the manufacturer’s

instructions.
5.4.2.5.1.1 Quantitative testing
Replace the first two paragraphs with the following:

For the quantitative enumeration test, a level of approximately 100 cfu is necessary to achieve sufficient

precision (see Table 1). This can necessitate the use of more than one plate.

A practicable range of 80 cfu to 120 cfu per plate with a minimum number of 50 cfu per plate should

be used. The use of more than one plate will increase the precision. For filters, the same number of

cfu is needed using one or more filters. Table 1 shows the 95 % confidence intervals associated with

colony counts.
