Overview

ISO/TS 22358: Traditional Chinese medicine - Procedure for reporting indoor air quality when combusting moxibustion devices provides a standardized procedure for evaluating and reporting indoor air quality when burning moxibustion devices. This technical specification supports health and safety by enabling stakeholders-such as manufacturers, intermediaries, and regulatory bodies-to systematically compare indoor pollutant concentrations resulting from moxibustion with international, regional, or national air quality standards. The document is specifically intended for combustible moxibustion devices and excludes electric and infrared moxibustion equipment as referenced in ISO 21292:2020 and ISO 20493:2018.

Key Topics

• Indoor Air Quality Assessment
  Defines a procedure for assessing and reporting the safety of indoor air quality during the combustion of moxibustion devices, including identification and quantification of pollutants such as carbon monoxide, nitrogen dioxide, volatile organic compounds (VOCs), and aldehydes.

• Emission Measurement and Calculation
  Provides a framework for conducting combustion tests and converting pollutant emission data into indoor air concentration values using standardized methods. This includes provisions for both ventilated and non-ventilated scenarios.

• Comparative Analysis with Standards
  Outlines steps to compare measured indoor concentrations against applicable air quality regulations, standards, or guideline values to determine safety and compliance.

• Documentation and Reporting Protocols
  Includes standardized request and report forms to facilitate clear communication and traceability between intermediaries and manufacturers in business transactions.

• Risk Mitigation Recommendations
  Guides the proposal of ventilation or other mitigation measures if pollutant levels exceed standard values during simulated use scenarios.

Applications

• Traditional Chinese Medicine (TCM) Facilities
  Clinics, wellness centers, and hospitals using combustible moxibustion devices can utilize this standard to ensure patient and practitioner safety by evaluating indoor air quality risks.

• Product Manufacturers
  Producers of moxibustion devices can adopt these protocols to demonstrate compliance with relevant air quality standards in different markets, enhancing product credibility and acceptance.

• Regulatory Authorities and Inspectors
  National or local health and safety regulators can reference ISO/TS 22358 in the assessment of moxibustion devices for import, sale, or professional use, ensuring that air quality impacts are within legal limits.

• Business-to-Business (B2B) Transactions
  The standard supports clear information exchange between intermediaries and manufacturers, particularly for international trade, by specifying required documentation on air quality safety.

Related Standards

• ISO 21366: Traditional Chinese medicine - General requirements for smokeless moxibustion devices
  Covers requirements for devices designed to minimize smoke, complementing ISO/TS 22358 for non-combustion alternatives.

• ISO 16000-3 & ISO 16000-6: Indoor Air Quality
  Specify methodologies for measuring formaldehyde, carbonyl compounds, and volatile organic compounds in indoor environments.

• ISO 15011-2: Health and safety in welding and allied processes
  Provides laboratory methods for sampling and determining emission rates of gases relevant to indoor air quality evaluation.

• ISO 21292:2020 and ISO 20493:2018
  Address electric and infrared moxibustion-like instruments, which fall outside the combustion-related scope of ISO/TS 22358.

---

Using ISO/TS 22358 helps ensure responsible use of moxibustion therapy by proactively managing indoor air quality risks, safeguarding health, complying with regulatory requirements, and facilitating transparent business operations in traditional Chinese medicine.

Introduction
Traditional moxibustion methods use the heat of combustion of moxa floss to maintain and promote
human health and to treat diseases. At the same time, however, combustion products are generated during
moxibustion treatment.
Meanwhile, there has been increased awareness and concerns about indoor air pollution caused by
chemicals in recent years. Therefore, people have come to avoid exposure to smoke and its by-products from
combustion.
There is a demand to provide information to protect people from the health effects of air pollutants by using
indoor air quality as a measure that quantifies the chemicals in the air inside a building.
Currently, standards have been established for the amounts of pollutants in the air, and procedures are
being implemented to protect human health from air pollution. Ambient air pollution refers to air pollution
found outdoors, while indoor air pollution occurs inside buildings and structures. Both are harmful to
human health and share many commonalities, but there are also differences in environmental conditions
and pollution sources. For chemicals used in moxibustion devices, which are primarily used indoors, indoor
air quality is based on the indoor environment.
To determine the chemical substances emitted from a product, a testing method using a chamber system, i.e.
the chamber method, is generally used to measure the amount of chemical substances emitted per product
mass or per usage time. However, because various standard and guideline values represent chemical
substance concentrations in the ambient as well as indoor air, it is not possible to directly compare the
emission amounts obtained using the chamber method with these standard values to evaluate the impact of
chemical substances emitted from a product in the indoor environment.
Therefore, a calculation procedure is required to convert the emission amount of the target pollutants into
an indoor air concentration value underdefined usage conditions (e.g. Space volume, ventilation rate, usage
time, etc.) and to compare this value with applicable standard or guideline values. This document specifies
this calculation procedure to evaluate the impact of pollutants generated when combusting moxibustion
devices in an indoor environment.

4 Procedure
Formatted
...
4.1 4.1 General Formatted
...
Formatted
...
The procedure for preparing a report on indoor air quality when combustion of moxibustion devices is
Formatted
...
specified in 4.2 to 4.7.4.2 to 4.7.
Formatted
...
4.2 4.2 Step 1
Formatted
...
Formatted
In international business-to-business (B to B) transactions, the intermediary handling a moxibustion device
...
that generates combustion products can submit a request form to the moxibustion device manufacturer to
Formatted
...
check indoor air quality when combusting a moxibustion device.
Formatted
...
The information to be included in the request form is set out in Clause 5.Clause 5.
Formatted
...
Formatted
...
NOTE 1 When preparing a report, it is assumed that both the intermediary and the manufacturer are aware of the
regulations, standards, or guidelines regarding air quality and indoor air pollutant concentrations in the country or Formatted
...
region where the moxibustion device in question is used.
Formatted
...
Formatted
NOTE 2 Compliance with applicable legal and regulatory requirements is outside the scope of this document. .

4.3 4.3 Step 2
Formatted
...
The moxibustion device manufacturer receives the indoor air quality inspection request form for the
Formatted
...
moxibustion device and proceeds with the report preparation procedures from Steps 3 to 6.
Formatted
...
An example checklist for reporting the indoor air quality when combusting the moxibustion devices is
Formatted
...
provided in Annex C.Annex C.

4.4 4.4 Step 3 Formatted
...
Formatted
...
4.4.1 4.4.1 For the calculation of indoor air quality, measurement of the quantity of pollutants is required.
Formatted
A combustion test to measure the quantity of pollutants shall be conducted by combusting the moxibustion
...
device in the test chamber and quantifying the target pollutants in the emitted combustion gases.
Formatted
...
4.4.2 4.4.2 Quantitative analysis of pollutants shall be performed according to the target pollutants and Formatted
...
their test methods specified in ISO 21366 or any other method proven equally suitable.
Formatted
...
4.4.2.1 4.4.2.1 Carbon monoxide (CO) Formatted
...

...
For the determination of carbon monoxide, test methods shall be in accordance with ISO 15011-2.
Formatted
...
4.4.2.2 4.4.2.2 Nitrogen dioxide (NO2)
Formatted
...
Formatted
...
For the determination of nitrogen dioxide, test methods shall be in accordance with ISO 15011-2.
Formatted

4.4.2.3 4.4.2.3 Total Volatile Organic Compounds (TVOCs)
Formatted
...
Formatted
For the determination of total volatile organic compounds, test methods shall be in accordance with ISO
...
16000-6.
