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 29042-7 was prepared by Technical Committee ISO/TC 199, Safety of machinery.
ISO 29042 consists of the following parts, under the general title Safety of machinery — Evaluation of the
emission of airborne hazardous substances:
⎯ Part 1: Selection of test methods
⎯ Part 2: Tracer gas method for the measurement of the emission rate of a given pollutant
⎯ Part 3: Test bench method for the measurement of the emission rate of a given pollutant
⎯ Part 4: Tracer method for the measurement of the capture efficiency of an exhaust system
⎯ Part 5: Test bench method for the measurement of the separation efficiency by mass of air cleaning
systems with unducted outlet
⎯ Part 6: Test bench method for the measurement of the separation efficiency by mass of air cleaning
systems with ducted outlet
⎯ Part 7: Test bench method for the measurement of the pollutant concentration parameter
A room method for the measurement of the pollutant concentration parameter and a decontamination index
are to form the subjects of future parts 8 and 9.

Introduction
The structure of safety standards in the field of machinery is as follows:
a) type-A standards (basic safety standards) giving basic concepts, principles for design, and general
aspects that can be applied to all machinery;
b) type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard that
can be used across a wide range of machinery:
⎯ type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
⎯ type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure sensitive
devices, guards);
c) type-C standards (machine safety standards) dealing with detailed safety requirements for a particular
machine or group of machines.
This part of ISO 29042 is a type-B standard as stated in ISO 12100.
The requirements of this document can be supplemented or modified by a type-C standard.
For machines which are covered by the scope of a type-C standard and which have been designed and built
according to the requirements of that standard, the requirements of that type-C standard take precedence.
ISO/TC 199 has a mandate in this area to produce type-A and type-B standards, which will allow verification
of conformity with the essential safety requirements.
ISO 29042-7 is based on EN 1093-8:1998, amended by Amendment 1:2008, published by the European
Committee for Standardization (CEN).

INTERNATIONAL STANDARD ISO 29042-7:2010(E)

Safety of machinery — Evaluation of the emission of airborne
hazardous substances —
Part 7:
Test bench method for the measurement of the pollutant
concentration parameter
1 Scope
This part of ISO 29042 specifies a test bench method for the measurement of the pollutant concentration
parameter of a given airborne hazardous substance from a machine, using a test bench under specified
operating conditions. The method is applicable only to the determination of emitted gases, vapours and
respirable particles. It is intended that whenever possible the emission rate be determined in a test bench (see
ISO 29042-3).
Measurement of the pollutant concentration parameter of a machine can serve for the
a) evaluation of the performance of the machine,
b) evaluation of the improvement of the machine,
c) comparison of machines within different groups of machines with the same intended use (such groups
being defined by the function and materials processed),
d) ranking of machines from the same group according to their pollutant concentration parameters, and
e) determination of the state of the art of a machine with respect to its pollutant concentration parameter.
