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
A dermal needle is a traditional Chinese medicine device for stimulating acupuncture points, meridians
or skin by tapping or rolling. It is composed of a group of needles which stimulate a wide area of skin
effectively. The stimulating strength of dermal needles depends on the density of the needles, the
sharpness of the needle tips and the length of the needle body, among other things.
Dermal needles are widely used in East and Southeast Asia, the Americas, Europe and Oceania.
According to different operation modes, dermal needles for single use may be divided into two types:
tapping-type and roller-type.
This document applies to roller-type dermal needles for single use.
