Introduction
Many different methods are used to determine the concentration of chemical and biological agents in
workplace air. Many of these methods involve the use of a pump and sampler connected by a flexible
tube. Air is drawn through the sampler and chemical and biological agents are trapped, e.g. on a filter,
sorbent tube or long-term detector tube, or in a gas washing bottle. In personal sampling, the pump and
sampler are attached to the worker so as to collect chemical and biological agents in the breathing zone.
The volume of air drawn by the pump during the sampling period is one of the quantities in the calculation
of the concentration of the chemical and biological agents in air. Therefore, the volume of air sampled
should be determined accurately and, in order to facilitate this, the flow rate should be maintained
within acceptable limits throughout the sampling period. For particle size selective sampling, the short-
term fluctuation of the flow rate should also be maintained within acceptable limits in order to ensure
that the sampler exhibits the required collection characteristics.
[1]
EN 482 specifies general performance criteria for methods for measuring the concentration of
chemical and biological agents in workplace air. These performance criteria include maximum values of
expanded uncertainty that are not to be exceeded under prescribed laboratory conditions. In addition,
the performance criteria should also be met under a wider variety of environmental influences,
representative of workplace conditions. The contribution of the sampling pump to measurement
uncertainty should be kept to a minimum.
This International Standard is intended to enable manufacturers and users of personal sampling pumps to
adopt a consistent approach to, and provide a framework for, the assessment of the specified performance
criteria. Manufacturers are urged to ensure that pumps meet the requirements laid down in this
International Standard, including environmental influences which can be expected to affect performance.

5 Requirements
5.1 Features
The pump shall have the following features:
a) an automatic control which keeps the volume flow rate nominally constant;
b) a means to reduce the likelihood of unintentional or unauthorized adjustment of any pump control,
such that it is concealed beneath a cover, can only be actuated with the aid of a tool or requires
specialized knowledge for operation;
c) either a malfunction indicator which, following completion of sampling, indicates that the air flow
has been reduced or interrupted during sampling, or an automatic cut-out which stops the pump if
the flow rate is reduced or interrupted;
d) a fuse or resettable breaker which interrupts the current in the electrical circuit of the pump in the
case of excessive current drain;
e) a filter which prevents particles from being drawn into the mechanism of the pump;

5.3 Design safety
The outer case of the pump shall be so designed that there are no sharp corners or other uncomfortable
protruding parts.
5.4 Operating time
The operating time shall be at least 1 h and should preferably be greater than 8 h. This applies to the
complete nominal flow rate range against the pressure drops as specified in Table 4 at (5 ± 2) °C.
NOTE The capacity of a battery increases with temperature. Therefore, the test is performed towards the
lower end of the temperature range in which the pump is likely to be used.
For the duration of the operating time, the flow rate shall not deviate by more than 5 % from the initial value.
The manufacturer shall report, in the instructions for use, the operating time at the specified pressure

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 13137 was prepared by Technical Committee ISO/TC 146, Air quality, Subcommittee SC 2, Workplace
atmospheres and by Technical Committee CEN/TC 137, Assessment of workplace exposure to chemical and
biological agents in collaboration.

Introduction
Many different methods are used to determine the concentration of chemical and biological agents in
workplace air. Many of these methods involve the use of a pump and sampler connected by a flexible tube. Air
is drawn through the sampler and chemical and biological agents are trapped, for example, on a filter, sorbent
tube or long-term detector tube or in a gas washing bottle. In personal sampling, the pump and sampler are
attached to the worker so as to collect chemical and biological agents in the breathing zone.
The volume of air drawn by the pump during the sampling period is one of the quantities in the calculation of
the concentration of the chemical and biological agents in air. Therefore, the volume of air sampled should be
determined accurately and, in order to facilitate this, the flow rate should be maintained within acceptable
limits throughout the sampling period. For particle size selective sampling, the short-term fluctuation of the
flow rate should also be maintained within acceptable limits in order to ensure that the sampler exhibits the
required collection characteristics.
EN 482 specifies general performance criteria for methods for measuring the concentration of chemical and
biological agents in workplace air. These performance criteria include maximum values of expanded
uncertainty that are not to be exceeded under prescribed laboratory conditions. In addition, the performance
criteria should also be met under a wider variety of environmental influences, representative of workplace
conditions. The contribution of the sampling pump to measurement uncertainty should be kept to a minimum.
This International Standard should enable manufacturers and users of personal sampling pumps to adopt a
consistent approach to, and provide a framework for, the assessment of the specified performance criteria.
Manufacturers are urged to ensure that pumps meet the requirements laid down in this International Standard,
including environmental influences which can be expected to affect performance.

ISO/DIS 13137
e) a filter which prevents particles from being drawn into the pump's mechanism;
f) a means to secure the pump on a person (integrated or available as an accessory).
NOTE Some pumps use internal sensors to provide atmospheric, pressure and air flow data. Information on the use
of these sensors is given in Annex B.
5.2 Mass
The mass of the pump, including batteries and integral holders, shall not exceed 1,2 kg for sampling pumps
-1

The operating time shall be at least 1 h and should preferably be greater than 8 h. This applies to the
complete nominal flow rate range against a specified pressure drop at (5 ± 2) °C.
NOTE The capacity of a battery increases with temperature. Therefore, the test is performed towards the lower end
of the temperature range the pump is likely to be used.
For the duration of the operating time, the flow rate shall not deviate by more than 5 % from the initial value.
The manufacturer shall report, in the instructions for use, the operating time at the specified pressure drop
according to 5.10 for the flow rates given in Table 1 at (5 ± 2) °C.
