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
Cleanroom gloves have long been used in the critical environments of the electronic, disk drive,
semiconductor, as well as storage media industries. The quest for a cleaner glove, in new emerging
industries of thin-film transistor (TFT), liquid-crystal display (LCD), nanotechnology, bio-medical
applications, has ensured that this is a growing market.
The basic function of cleanroom gloves is to ensure minimal transfer of contaminants onto the products
or components being processed or manufactured in a clean environment. Such contaminants will
always be present in the exposed hands of the personnel. It is for this purpose that the hands need to be
gloved. However, such gloves must have minimal contaminants on its surface, thus the need for the use
of cleanroom gloves.
The principal contaminants that could compromise the quality or the integrity of the product or process
in a critical environment are submicron particles, ionic chemical contaminants, non-volatile chemical
components, as well as silicone, amide or dioctyl phthalate (DOP). In the cleanroom industry, these
parameters are known as particle count, ionic content, total non-volatile residue (TNVR) and silicone,
amide or DOP content.
Depending on the criticality of the operational environment, the appropriate cleanroom glove will need
to be used. Hence, a very crit
