ISO 13137:2013(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 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.

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;
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

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

6 © ISO 2013 – All rights reserved

ISO 13137:2013(E)
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 an appropriate number
of charging and operating cycles (see Clause 10 for charger).
For pumps with a nickel–cadmium (NiCd) battery, perform at least five cycles. Wherever possible, the
use of this battery type should be avoided for reasons of environmental protection and to avoid problems
with battery memory effects.
For pumps with a nickel–metal hydride (NiMH) battery or a lithium-ion (Li-ion) type battery, perform
at least three cycles.
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 volume 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 ±10 % of the required value.
If an integral flow meter is incorporated in the pump this shall not be used to adjust the flow rate.
NOTE 1 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 2 The pressure drop settings for the technical tests include the flow resistance of the connected volume
flow meter or volume meter (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.
Key
1 volume flow meter or volume meter 4 pulsation damper (optional)
2 air flow resistor 5 pump
3 differential pressure gauge (manometer)
Figure 1 — Test set-up for pumps operating with a variable flow resistance
Air is drawn through a volume flow meter or volume meter. The flow resistor, adjusted depending on
the test to be performed, is connected by one end to the outlet of the volume flow meter, and by the
ISO 13137:2013(E)
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 volume flow meter and differential
−1
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 diameter and length of the tubing used should be as low as
possible with a maximum total length of (80 ± 5) cm and a nominal internal diameter of 6 mm. For
higher flow rates, larger diameter tubing may be used to limit pressure restriction. For the pulsation
test given in 7.7, 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.

pressure drop setting by linear interpolation.
7.5.3 Procedure
Perform the test for each flow rate and pressure drop condition specified in 7.5.2, once at a temperature
in the range from 20 °C to 25 °C and once at (5 ± 2) °C.
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).
7.6 Short-term interruption of air flow
7.6.1 Test set-up
The basic set-up is as given in 6.5.
7.6.2 Flow rate and pressure drop adjustment
The test is carried out at the flow rate and pressure drop as specified in Table 5.

7.6.3 Procedure
Adjust the pump and resistor to the required flow rate and pressure drop as specified in 7.6.2. Fully
block the air flow by fixing a hose clamp on the tubing at the inlet of the pump. Measure the time taken
for the pump to react to the blockage (e.g. automatic cut out, activation of malfunction indicator) using a
timer. Afterwards remove the clamp and check whether the requirements specified in 5.6 are met.
7.7 Temperature dependence
7.7.1 Test set-up
The basic set-up is as given in 6.5. The complete test set-up is located in a climatic chamber.
7.7.2 Flow rate and pressure drop adjustment
The test is carried out at the flow rate and pressure drop as specified in Table 6.

7.7.3 Procedure
Prior to the test, fully charge the battery and then condition the complete test set-up (see 6.5) by storing
at the temperature range from 20 °C to 25 °C for at least 16 h. Switch the pump on and adjust the flow rate
and pressure drop to the required values. Place the complete test set-up in the climate chamber at (5 ±
2) °C for about 2 h with the pump running, then measure the flow rate. Then increase the temperature to
10 °C, 20 °C, 30 °C, and 40 °C and keep constant for periods of (60 ± 1) min at each temperature. Measure
the flow rate at the end of each 1 h period.

ISO 13137:2013(E)
Pumps with operating times less than about 8 h shall not be run over the entire test period. Once
each required temperature is reached, switch on the pump and run for (15 ± 1) min prior to flow rate
measurement, then switch off the pump upon completion of flow rate measurement.
Check whether the requirement specified in 5.7 is met.
If the temperature range specified by the manufacturer exceeds the range from 5 °C to 40 °C the test
should be performed over this extended temperature range. In this case, the temperature steps should
be adjusted accordingly but should not exceed 10 °C.
