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/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 126, Tobacco and tobacco products.

This fourth edition cancels and replaces the third edition (ISO 16055:2019), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— the title and scope have been modified by adding “for smoking” machine;

— the former Annex A (Control charts) has been deleted and the subsequent annex has been moved;

— a reference to ISO 7870-2 has been added in place of the omitted Annex A.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

3.1
monitor test piece

sample produced for a specific test purpose, validated to fulfil requirements within specified tolerances

and intended to be used for laboratory purposes only and labelled to clearly indicate that it is not for

human use

Note 1 to entry: A monitor test piece is a sample taken from a batch of cigarettes that show the greatest

homogeneity with regard to their physical, chemical and smoke yield characteristics.

3.2
analysis value

result of a smoking test and analysis carried out following ISO 4387, ISO 8454, ISO 10315 and ISO 10362-1

(or ISO 10362-2) or, for intense smoking, following ISO 20779, ISO 22947 and ISO 22253, respectively

4 Requirements
4.1 The monitor test pieces shall be produced from one production batch.

4.2 The number of monitor test pieces produced shall be sufficient to cover the needs of a period of at

least two years.

4.3 For reasons of homogeneity, the cut tobacco used shall be taken from one well-mixed batch (if

possible, it is advisable to use a single grade of tobacco with no addition of further materials, such as

stems, humectants or flavours, to avoid unnecessary heterogeneity of the blend).

4.4 The non-tobacco materials used, such as cigarette paper and filters, shall be taken from one

production batch and strict quality-control measures shall be applied during the production of the filters.

Recommended specifications for the production of the monitor test piece are given in Annex A.

The requirements shall include a stable yield for carbon monoxide which is best obtained with a non-

ventilated filter. Therefore, the recommendation is that the monitor test piece is unventilated.

If it is necessary to use humectants for the tobacco, only glycerol is allowed. Propylene glycol cannot be

used due to its high vapour pressure, which can lead to uncontrolled (undetected) loss of mass during

conditioning.

4.5 The production tolerances on tobacco mass, circumference and draw resistance of the monitor test

piece shall be controlled as precisely as possible.

It is normally necessary to modify production practices to obtain the required consistency in physical,

chemical and smoke yields of the monitor test pieces (see example for CORESTA Monitor Test Piece in

Table A.2).

Mass control is critical in the production of a reliable monitor test piece. Excessive mass variation

contributes to unacceptable variation in smoke yields.

4.6 The monitor test pieces in a lot shall show consistent values for the content of nicotine-free dry

particulate matter, nicotine and carbon monoxide in their smoke yields under the use of the smoking

regime specified in ISO 3308 and for the content of nicotine and carbon monoxide under the use of

smoking regime specified in ISO 20778. This consistency shall be assessed by means of a comparative

study of sufficient size; the size chosen depending on whether the monitor is for local or broader use (see

ISO 5725-2).

4.7 The packaged monitor test pieces shall be stored at a temperature below or equal to +4 °C until

they are to be used.

ISO 16055:2021(E)

NOTE Other reference standards in the tobacco field require a storage temperature below −16 °C for reasons

of hygiene. Normally, a storage temperature of +4 °C is sufficient for monitor test pieces.

4.8 The product design shall ensure that the smoke yields (nicotine-free dry particulate matter,

nicotine and carbon monoxide) are sufficiently high per monitor test piece (see example in Table A.4) so

that the influence from a possible offset in the smoking machine settings can be distinguished from the

normal variation of the smoke yields.

4.9 It is essential to make the monitor test piece clearly distinguishable from commercial cigarettes.

The monitor test pieces shall be packed in hard boxes of 20 which should
