Foreword
This document (prEN 1093-1:2007) has been prepared by Technical Committee CEN/TC 114 “Safety of
machinery”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1093-1:1998.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this
document.
This part 1 of EN 1093 Safety of machinery - Evaluation of the emission of airborne hazardous substances
belongs to a series of documents, the other parts of which are the following:
 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: Capture efficiency of an exhaust system, tracer method;
 Part 6: Separation efficiency by mass, unducted outlet;
 Part 7: Separation efficiency by mass, ducted outlet;

Introduction
The structure of safety standards in the field of machinery is as follows:
 Type-A standards (basic safety standards) giving basic concepts, principles for design, and general
aspects that can be applied to all machinery;
 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);
 Type-C standards (machine safety standards) dealing with detailed safety requirements for a particular
machine or group of machines.
This European Standard is a type-B standard as stated in EN ISO 12100-1.
The provisions of this European Standard can be supplemented or modified by a type-C standard.
NOTE For machines which are covered by the scope of a type-C standard and which have been designed and built
according to the provisions of that standard, the provisions of that type-C standard take precedence over the provisions of
this type-B standard.
The concentration level of substances resulting from emission of airborne hazardous substances from
machines depends upon factors including:
 the emission rate of airborne hazardous substances ("pollutants") from the machine under examination,
depending of the type of process and the production rate of the machine;
 the performance of the pollution control system associated with the machine and, in the case of air
recirculation, the performance of the separation system;
 the surrounding conditions, especially the air flow pattern, which can reduce the pollution (efficient
general ventilation) or increase it (disturbing air, crossdraughts);
 the worker's location in relation to the machine and its pollution control system, and taking into account
the workers movements;
 the quality of maintenance; poor quality has generally an adverse effect on the performance of the
pollution control and the separation systems.
This European Standard concerns the first two points in this list and forms only part of a comprehensive risk
assessment. It is not for a risk assessment of the work place. Evaluating the parameters defined in this
European Standard leads to an evaluation of the performance of the machine and its associated pollution
control system.
This European Standard can be used as a part of verification described in EN 626-2.

1 Scope
This European Standard specifies parameters which can be used for the assessment of the emission of
pollutants from machines or the performance of the pollution control systems integrated in machines. It gives
guidance on the selection of appropriate test methods according to their various fields of applications and
types of machines including the effects of measures to reduce exposures to pollutants. The test methods are
given in additional parts of this standard (see Table 1 and Annex A).
This European Standard is not applicable for certain types of off-the-road vehicles powered by internal
combustion engines which are also subject to the Machinery Directive.
2 Normative references
The following referenced documents are indispensable for the application 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.

terminology, methodology (ISO 12100-1:2003).
3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following
apply.
3.1
uncontrolled emission rate of a given pollutant
&
m
u
mass of pollutant emitted from the machine into the space around the machine per unit of time
NOTE Any measures to reduce the air pollution around the machine (e.g. capture devices, containment equipment,
wetting process) should not in used or should be de-activated.
3.2
controlled emission rate of a given pollutant
&
m
k
mass of pollutant emitted from the machine into the space around the machine per unit of time, taking into
account the effects of measures to reduce the air pollution
NOTE Any measures to reduce the air pollution around the machine (e.g. capture devices, containment equipment,
wetting process) should be used or activated.

3.3
capture efficiency
η
c
ratio of the mass flow rate of a given pollutant directly collected by the pollutant
control system to the uncontrolled mass flow rate of this pollutant emitted from the machine
NOTE 1 The capture efficiency, as a percentage, can be calculated by the following equation:
& &
m − m
u k
η = ⋅100 (1)
c
&
m
u
& &
This equation is applicable only if m – m represents the pollutant mass flow rate directly captured. This parameter is
u k
not usable when the amount of emission is effected by the control system.
NOTE 2 Where the pollutant control system is an exhaust ventilation system and provided comparable discharge and
flow patterns of the real pollutant can be simulated by a tracer technique the equation becomes:
q
C
η = ×100 (2)
c
q
E
where:
q is the flow rate of tracer collected by the exhaust system during operation;
C
q is the flow rate of tracer emitted (measured by emitting the tracer directly into the exhaust
E
system during the first phase.
NOTE 3 For further details see EN 1093-4:1996, Clause 5.
3.4
separation efficiency by mass
η
s
ratio of the mass of pollutant retained by the air cleaning system (m ) to the mass of
3
pollutant entering the air cleaning system (m ) during a given period

NOTE 1 For special applications the number of fibres or particles is measured instead of the mass.
NOTE 2 The separation efficiency of an air cleaning system, as a percentage, can be calculated by the following
equation:
m

η = ×100 (3)

NOTE 3 In certain cases it can be necessary to consider only that part of pollutants (e. g. size of particles) which is
actually hazardous for exposed persons; e. g. separation efficiency of a separation system against hazardous dust is
measured as a function of particle size – otherwise the results are possibly not be reliable for health and safety purposes.
