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

This document was prepared by Technical Committee ISO/TC 198, Sterilization of health care products.
This second edition cancels and replaces the first edition (ISO 11138-5:2006), which has been
technically revised.

ISO 11138-5:2017(E)
Introduction
ISO 11138-1 specifies production, labelling, test methods and performance requirements for the
manufacture of biological indicators including inoculated carriers and suspensions intended for use
in validation and monitoring sterilization processes. This document gives specific requirements for
those biological indicators intended for use in low-temperature steam and formaldehyde sterilization
processes.
Annex B gives rationale for the liquid-phase test method for low-temperature steam and formaldehyde
biological indicators.
The ISO 11138 series represents the current “state-of-the-art” according to the experts representing
manufacturers, users and regulatory authorities involved in developing the standard. The intent is
not to promote the use of biological indicators where such use is not advised, but to provide common
requirements for the production of those biological indicators that are known to be in use today.
A standard exists providing general requirements for the validation and control of low-temperature
steam and formaldehyde sterilization processes (see ISO 25424).
NOTE It is possible that some countries or regions have published other standards covering requirements
for sterilization or biological indicators.
Advice on selection, use and interpretation of results when using biological indicators can be found in
ISO 14161.
