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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 15011-5 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 9, Health and safety.
This first edition cancels and replaces ISO/TS 15011-5:2006, which has been technically revised.
ISO 15011 consists of the following parts, under the general title  Health and safety in welding and allied
processes — Laboratory method for sampling fume and gases:
—  Part 1: Determination of fume emission rate during arc welding and collection of fume for analysis
—  Part 2: Determination of emission rates of carbon monoxide (CO), carbon dioxide (CO ), nitrogen monoxide
(NO) and nitrogen dioxide (NO ) during arc welding, cutting and gouging
—  Part 3: Determination of ozone emission rate during arc welding
—  Part 4: Fume data sheets
—  Part 5: Identification of thermal-degradation products generated when welding or cutting through products

ISO 15011-5:2011(E)
Introduction
Welding and allied processes generate fume and gases, which, if inhaled, can be harmful to human health.
Knowledge of the composition and the emission rate of the fume and gases can be useful to occupational
hygienists in assessing worker exposure and in determining appropriate control measures.
[1] [2]
ISO 15011-1  and ISO 15011-2  have been promulgated primarily to generate emission rate data when welding
uncoated metals. However, it is now common practice in the welding industry to weld or cut through a variety of
coatings that are composed wholly or partly of organic materials. These coatings include shop primers, paints,
oils, waxes and inter-weld materials such as adhesives and sealants. When heated, these coatings give rise
to a wide range of thermal degradation products, the composition of which depends upon the temperatures to
which the coatings are subjected. During welding and cutting activities, the coating material is subjected to a
range of temperatures due to the existence of temperature profiles within the material being processed.
The purpose of this part of ISO 15011 is to describe procedures that can be used to identify and make
semi-quantitative measurements of the organic components generated when welding and cutting, preheating
and straightening metal treated with the coatings mentioned above, with a view to identifying those components
that are significant hygienically. The data generated can be used to provide information on degradation
products for use on safety data sheets. If desired, the degradation products identified in these tests can then
be measured quantitatively using existing standards for making workplace exposure measurements.
Comparative testing of various weld-through coatings has been carried out using laboratory based heating
[3][4][5]
tests, pyrolysis, and different welding techniques . From the results of these tests, it was decided that
[6]
pyrolysis should be adopted as the basis for the testing procedure  prescribed in this part of ISO 15011. This
was based on the following observations and conclusions:
—  pyrolysis successfully identifies most of the hygienically significant components;
—  despite the fact that pyrolysis tests are carried out in an atmosphere of helium, results are very comparable
with those obtained in air by thermal decomposition in a furnace;
—  the cost of pyrolysis testing is significantly lower than the cost of welding tests;
—  pyrolysis test results show good interlaboratory consistency;
—  it is easier to define standard conditions for pyrolysis tests than for welding tests; and
—  in order to reduce the sampling regime required, any welding test programme would, in all likelihood, need
to incorporate some pre-testing in the laboratory, probably using pyrolysis.

INTERNATIONAL STANDARD ISO 15011-5:2011(E)
Health and safety in welding and allied processes — Laboratory
method for sampling fume and gases —
Part 5:
Identification of thermal-degradation products generated when
welding or cutting through products composed wholly or partly
of organic materials using pyrolysis-gas chromatography-
mass spectrometry
1 Scope
This part of ISO 15011 specifies procedures for obtaining information about thermal degradation products
generated when welding, cutting through, preheating and straightening metal treated with coatings composed
wholly or partly of organic substances, e.g. shop primers, paints, oils, waxes and inter-weld materials such
as adhesives and sealants. It is aimed primarily at test laboratories performing such procedures. The data
generated can be used by coating manufacturers to provide information for inclusion in safety data sheets
and by occupational hygienists to identify thermal degradation products of significance in the performance of
risk assessments and/or workplace exposure measurements. The data cannot be used to estimate workplace
exposure directly.
This part of ISO 15011 is applicable to all coatings composed partly or wholly of organic materials that can be
heated during welding and cutting, preheating and straightening to temperatures at which thermal degradation
products are generated and where it is not apparent what those degradation products are.
