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. 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

Footwear and footwear components — Test method to
assess antibacterial activity
CAUTION — Test methods specified herein require the use of bacteria. These tests are only to
be carried out in facilities with containment techniques for handling microorganisms and by
persons with training and experience in the use of microbiological techniques. Appropriate safety
precautions are to be observed with due consideration given to country-specific regulations.
1 Scope
This International Standard specifies quantitative test methods to evaluate the antibacterial activity of
footwear and components.
This International Standard is applicable to all types of footwear and components employing non-
diffusing antibacterial treatments.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 3696, Water for analytical laboratory use — Specification and test methods
ISO 19952, Footwear — Vocabulary
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 19952 and the following apply.
3.1
antibacterial activity
efficacy of a material or finish used to prevent or mitigate the growth of bacteria, to reduce the number
of bacteria or to kill bacteria
3.2
control sample
material identical to the test material but without antibacterial treatment
4 Safety
Handling of microorganisms which are potentially hazardous requires a high degree of technical
competence and can be subject to current national legislation and regulations. Only personnel trained
in microbiological techniques should carry out such tests. Codes of practice for disinfection, sterilization
and personal hygiene shall be strictly observed.
NOTE It is recommended that workers consult IEC 60068–2-10, appendix A “Danger to personnel”, and ISO 7218.

Type Culture Collection.
7.2 Storage of strains
Inoculate the strains to the nutrient agar (NA) (6.3), and incubate at (37 ± 2) °C for 24 h. Store at (5 ± 3) °C
(maximum one month) and keep it as stock culture of the strains. Transfer and incubate one time each month.

number of bacteria with microscopic observation or other methods. Prepare physiological saline (6.5)
with 1 % nutrient broth (NB) (6.2). Use this media to prepare a suspension with a bacterial concentration
5
