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).

Introduction
Recent analyses of male condom samples from different manufacturers that have failed the freedom
from holes test suggest that some of the holes observed in the samples are caused by damage when
the samples are being prepared for testing in the laboratory. There have also been reports of incorrect
results when testing condoms for bursting volume and pressure caused by poor handling of the
condoms, for example by excessively stretching the samples when mounting them on the burst testing
apparatus. This leads to the development of a guidance for preparation procedures of test samples or
test pieces such as test for holes and bursting volume and pressure.
An interlaboratory study comparing the results for tests for freedom from holes and burst properties
from different laboratories has been completed. Thin natural rubber latex condoms and polyurethane
condoms were used in this study. The study identified various handling procedures that could lead to
incorrect results. Based on this study, a set of standardized handling procedures have been developed
to minimize the risk of incorrect results being obtained.
This document describes these standardized handling procedures which are designed to minimize
unintentional damage to the condoms during sample preparation and testing procedure in the
laboratory. It is expected for the procedures described in this document to improve the reproducibility
of test results between laboratories. This document helps improve the precisions of mechanical testing
for male condoms as specified in ISO 4074 and ISO 23409.
The guidance given in this document is intended for laboratory testing only. It is not intended for
condom users and should not be included in the instructions for use for condom users.
