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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
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 www .iso .org/

This document was prepared by Technical Committee ISO/TC 249, Traditional Chinese medicine.
This second edition cancels and replaces the first edition (ISO 18666:2015), of which it constitutes a
minor revision. The changes to the previous edition are as follows:
— Introduction: the term 'International Standard' changed to 'document' in the first and third
paragraphs; improvement of English expression to 'increasing expectations and concerns by
patients' and the term 'ensure' changed to 'guide' in the second and third paragraphs;
— Scope: the term 'International Standard' changed to 'document' in the first and third paragraphs;
minor editorial change of the term 'uses' to 'use' in the second paragraph;
— Clause 3: addition of the introductory text according to ISO/IEC Directives, Part 2;
— 3.4: deletion of the phrase 'during treatment';
— 4.1.1: improvement of English expression for clarity;
— minor editorial changes.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document specifies the general requirements for safety and quality of moxibustion devices,
including the moxibustion materials used in such devices. The safety and quality of both moxibustion
devices and materials are closely related to moxibustion safety and quality.
There is a wide variety of moxibustion devices and materials currently available commercially, but there
are no standards guiding their manufacture and finishing. Increased interest and use of moxibustion,
as well as increasing expectations and concerns by patients regarding moxibustion safety and quality,
have given rise to the need to improve safety and quality of moxibustion through implementation of an
International Standard.
The primary aim of this document is to guide the safety and quality of moxibustion devices and
materials.
Annex A gives guidance on the methods that can be used to determine the moxibustion temperature at
the human body surface during treatment using the moxibustion device.
Annex B gives guidance on the method of artificial drying of mugwort leaves by heat.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 18666:2021(E)
Traditional Chinese medicine — General requirements of
moxibustion devices
1 Scope
This document specifies the general requirements for configuration, materials, performance and safety
requirements of moxibustion devices. It also specifies the minimum requirements for moxibustion
materials used in moxibustion devices.
It is applicable across a wide range of moxibustion devices that use moxa floss as the main combustion
material and can remain on or over the body throughout the moxibustion process. It is applicable to
moxibustion devices for both single and repeated usage.
This document does not apply to devices that imitate moxibustion, such as electro-moxibustion and
infrared moxibustion devices that do not involve the use of moxa floss. It also does not apply to moxa
floss used in direct moxibustion.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1
moxibustion device
apparatus that uses moxa floss as the main combustion material and is intended for single or repeated
usage
EXAMPLE Moxibustion with tube, such as a short moxa roll with a cardboard base and a moxa tube (made of
cardboard) that is single-use and developed as an alternative to direct moxibustion.
Note 1 to entry: Moxibustion devices include those accessories as defined by the manufacturers that are
necessary to enable the normal use of the moxibustion device.

4 Configuration
4.1 Structure
4.1.1 Size and shape
The size and shape of moxibustion devices can vary according to the intended use, such as on a specific
point or an area of the human body surface.
4.1.2 Visual inspection
When inspected by normal or corrected-to-normal vision:
a) the surface of the moxibustion device shall not have any obvious defects such as breakages,
protrusions, dents or rust that can cause accidental cuts or injuries to the user;
b) moxibustion devices for repeated use shall have a temperature-adjusting mechanism or other
appropriate arrangement to maintain moxibustion at an appropriate temperature;
c) except for moxibustion with tube, the body of the moxibustion device shall ensure that the removal
of ash is easy and shall be well ventilated to facilitate combustion; it should also contain:
