ISO 13137:2022(E)
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 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]
ISO 20581 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 document 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
document, including environmental influences which can be expected to affect performance.

4 Type of pump
Sampling pumps are classified according to their intended use as follows:
— type P: pumps for personal sampling of airborne particles;
— type G: pumps for personal sampling of gases and vapours.
NOTE 1 Type P pumps can be used for personal sampling of gases and vapours as long as they conform with
the type G pump requirements.
NOTE 2 For types of pump mechanism and control system. See Annex A.
5 Requirements
5.1 Features
The pump shall have the following features:
a) an automatic control which keeps the volumetric 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 deviates by more than 5 % or is 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;
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
−1
pumps with a flow rate of less or equal than 5 l ⋅ min and 2,5 kg for sampling pumps with a flow rate
−1
above 5 l ⋅ min .
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. The
ISO 13137:2022(E)
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.
For the duration of the operating time, the flow rate shall not deviate by more than 5 % from the initial
value.

NOTE Annex C describes regular tests that users can perform to maintain pumps and flow meters. These
tests are not required for conformance with this document.
5.5 Start-up and long-term performance
During operation of the pump at (5 ± 2) °C and in the range from 20 °C to 25 °C, the flow rate shall not
deviate by more than 5 % from the value measured at the start of the determination of the long-term
performance.
5.6 Short-term interruption of air flow
When the air flow is fully blocked, the pump shall cut out or the malfunction indicator activate. The
pump may try to restart automatically after the airflow is blocked. If the air flow is blocked for more
than (120 ± 10) s, the pump shall not restart automatically or the malfunction indicator shall remain
activated until reset.
NOTE Some sampling pumps are designed to restart automatically for a number of times after being blocked.
In this case, it is acceptable to restart automatically provided that the total time does not exceed 120 ± 10 s.
5.7 Temperature dependence
When the flow rate is set within the temperature range from 20 °C to 25 °C in accordance with 7.8, it
shall not deviate by more than 5 % after cooling down the sampling train to (5 ± 2) °C within about
2 h and running for a period of (60 ± 1) min when the temperature is changed to the next (fixed) value
within the range from 5 °C to 40 °C as stated in 7.8.3.
5.8 Mechanical strength
The general function of the pump shall not be impaired by shock treatment (see 7.9). No mechanical
damage or electrical defect shall occur.
After shock treatment, the flow rate measured shall not deviate by more than 5 % from the value
measured prior to shock treatment.
ISO 13137:2022(E)
5.9 Pulsation of flow rate (for type P pumps only)
For type P pumps, the pulsation shall not exceed 11 % of the mean volumetric flow rate. This is the
critical maximum value shown by experiment on several different designs of pumps to not alter the
size-separation performance of several different designs of cyclones (see References [3], [4] and [5]).
By recording the time curve of the volumetric flow rate the pulsation P is given as a percentage of the
mean volumetric flow rate by Formula (1):
T
1 2
ft()− ft d
∫
T
P= ×100 (1)
f
where
−1
f(t) is the volumetric flow rate with respect to time t, in litre per minute (l ⋅ min ), calculated
from the measurement of velocity;
−1
is the mean volumetric flow rate over time T, calculated in litre per minute (l ⋅ min ), from
f
the measurement of velocity;
t is the time, in seconds (s);
T is the time period of pulsation, in seconds (s).
The quantity f(t) is not necessarily the volumetric flow rate but shall have a direct linear relationship to
the volumetric flow rate.
NOTE P can be measured in several ways. See 7.10 for examples.
5.10 Flow rate stability under increasing pressure drop
−1
5.10.1 Pumps with a nominal flow rate range less or equal than 5 000 ml · min
When set within the nominal flow rate range of the pump, the flow rate shall not deviate by more than
±5 % from the initial value on changing the pressure drop within the range specified in Table 2.
The choice of pump is driven by the capability of the pump to pull air across the pressure drop. Annex D
lists measured pressure drops across typical collection substrates, supporting the selection of pump
type for a particular sampler. It is not necessary for a P-type or G-type pump to meet every flow rate or
pressure drop listed in Table 2. However, the requirement shall be met for the nominal flow rate range
specified by the manufacturer.

5.10.2 Pumps with a nominal flow rate range above 5 000 ml · min
When set within the nominal flow rate range of the pump, the flow rate shall not deviate by more
than ±5 % from the initial value on changing the pressure drop within the nominal pressure drop range
specified by the pump manufacturer.
5.11 Timer accuracy
If the pump has an internal timer, the indicated time shall not deviate by more than ±0,5 % from that of
a calibrated device to measure time (e.g. stopwatch).
5.12 Electromagnetic compatibility
The pump shall meet the requirements for electromagnetic compatibility according to IEC 61000-6-1
and IEC 61000-6-3.
5.13 Explosion hazard
If the pump is claimed to be suitable for use in areas subject to explosion hazard, the pump shall conform
with the requirements of IEC 60079-0.
6 Test conditions
6.1 Number of test objects
The tests given in Clause 7 may be carried out with one pump only unless otherwise stated in the
specific test clause.
6.2 Test instruments
The uncertainty of the test instruments shall be in accordance with Table 3.

uncertainty
Volumetric flow meter 2 %
Volumetric meter 2 %
Pressure gauge 3 %
Timer 0,1 %
Thermometer 1 °C
For a rapidly responding flow meter, such as a hot-wire anemometer, the response time shall be 4,5 ms
or less from t to t
10 90.
NOTE 1 Times t and t are those at which 10 % and 90 % of the final reading of the anemometer signal is
10 90
reached when a step signal is applied.
The temperature stability of the climatic chamber used shall be at least ±2 °C.
All test instruments listed in Table 3 shall have calibrations that are traceable to national standards.
NOTE 2 Annex E lists typical test instruments.
6.3 Preconditioning and sequence of tests
Prior to the technical tests (see Clause 7), precondition the pump by performing at least three charging
and operating cycles (see Clause 10 for charger).
Fully charge the battery in accordance with the manufacturer’s instructions and run the pump until it
automatically shuts down due to low battery status.
To reduce the cycle time, the pump should run at its maximum nominal flow rate and at 80 % of the
maximum of the required pressure drop range as in 5.10.
Following completion of the charging and operating cycles, perform tests in the order given in Clause 7.
6.4 Adjustment of volumetric flow rate and pressure drop
Flow rates shall be adjusted within a maximum deviation of ±5 % of the required value.
Pressure drops shall be adjusted within a maximum deviation of ±5 % of the required value.
If an internal flow meter is incorporated in the pump this shall not be used to adjust the flow rate.
The technical tests (see Clause 7) require the pump to be adjusted to specific flow rates and the flow
resistor to be adjusted to give specific pressure drops at the inlet of the pump. The required flow rates
and pressure drops are specified in the individual test clauses.
NOTE The pressure drop settings for the technical tests include the flow resistance of the connected
volumetric flow meter or volumetric meter (see Figure 1, label 1).
6.5 Test set-up and performance
The basic test set-up for the technical tests shall be as depicted in Figure 1.

Figure 1 — Test set-up for pumps operating with a variable flow resistance
Air is drawn through a volumetric flow meter or volumetric meter. The flow resistor, adjusted
depending on the test to be performed, is connected by one end to the outlet of the volumetric flow
meter, and by the other end to the inlet of the pump. The pressure drop relative to ambient pressure
is measured using a differential pressure gauge (manometer), connected to the line, and in between
the flow resistor and the inlet of the pump. The pump inlet is connected to the flow resistor and the
differential pressure gauge.
NOTE 1 Where pulsation of the air flow prevents accurate reading of the volumetric flow meter and
−1
differential pressure gauge, a pulsation damper of low flow resistance (up to 200 Pa at 2 l ⋅ min ) can be inserted
downstream of the differential pressure gauge.
All connections shall be leak tight. The length of connection between a volumetric flow meter or
volumetric meter and a pump shall not exceed 100 cm. For the pulsation test given in 7.8, special
requirements for the tubing and test set-up shall be fulfilled.
Tests shall be performed with fully charged batteries.
Unless otherwise specified, the tests shall be carried out at a range from 20 °C to 25 °C, and the
temperature shall be measured and recorded in the test report.
NOTE 2 If the measurement of the pressure drop is not necessary for a test, the differential pressure gauge
can be omitted.
7 Test methods
7.1 General
Among the test methods described in this clause, manufacturers shall test at least methods including
operating time, long-term performance, pulsation of flow rates, timer accuracy, and flow rate stability
under increasing pressure drop.
7.2 Features
Make a visual inspection and check the manufacturer’s specifications to determine that the pump
incorporates all features specified in 5.1.
7.3 Mass
Check the mass by weighing and compare the result with the requirement given in 5.2.
ISO 13137:2022(E)
7.4 Design safety
Determine whether the design safety requirements specified in 5.3 are met by visual inspection of the
pump.
7.5 Operating time
Carry out the operating time tests at (5 ± 2) °C in conjunction with the tests for start-up and long-term
performance (see 7.6).
Check whether the requirement specified in 5.4 is met.
7.6 Start-up and long-term performance
7.6.1 Test set-up
Perform all the tests using the basic test set-up given in 6.5 and carry out the tests at (5 ± 2) °C in a
climatic chamber.
7.6.2 Flow rate and pressure drop adjustment
Carry out the test at two flow rates and pressure drop conditions as specified in Table 4.
If the required flow rate setting falls between the values stated in Table 2, determine the required
pressure drop setting by linear interpolation.

7.6.3 Procedure
Perform the test for each flow rate and pressure drop condition specified in 7.6.2, once at a temperature
in the range from 20 °C to 25 °C and once at (5 ± 2) °C.
ISO 13137:2022(E)
Prior to each test, fully charge the battery and then condition the complete test set-up (see 6.5) by
storing at the required temperature for at least 16 h. Switch on the pump and adjust the flow rate
and pressure drop to the required values. Start the timer and measure the flow rate continuously.
Continue the test until the measured flow rate falls outside the ±5 % criterion set in 5.5, a malfunction
is registered or the pump cuts out automatically (see 5.1).
