comply with EN IEC 60079-0, EN 60079-1, EN 60079-2, EN 60079-5, EN 60079-6, EN 60079-7,
EN 60079-11, EN 60079-18 and EN 60079-25.
5.3 Mechanical construction
Every sampler shall be constructed in such a manner that it is easily accessible for regular function checks
and that airflow can easily be measured and calibrated. The sampling pump shall maintain the required
airflow rate throughout the sampling period.
Material used in the sampling head should be chosen to avoid moisture uptake and electrostatic charges.
5.4 Indicator devices
An indicator device shall be provided to show that the sampler is switched on. If the sampler has more
than one measuring range, the selected range shall be clearly identified.
NOTE It is an advantage if elapsed time indicators, low flow rate indicators, flow interrupted indicators are

5.10 Instruction handbook
The instruction handbook shall be written in a language, which is understandable in the country of the
operator. It shall be easily understood and every function explained.
The instruction handbook shall illustrate all components and their handling by figures.
The instruction handbook shall give the environmental conditions and other conditions under which the
sampler shall be operated including limitations to its use. It shall give exact calibration instructions and
recommended equipment (e.g. flow meters) to be used. The instruction handbook shall also give
instructions for troubleshooting and maintenance of the sampler.
5.11 Sampling efficiency
5.11.1 General
The sampling efficiency of samplers collecting biological agents comprises of a physical part, the physical
sampling efficiency (see 5.11.2) and the biological preservation efficiency (see 5.11.3).
The sampler should be able to collect a representative sample of the required health-related fraction of
the bioaerosol according to EN 481.
The health-related fraction to be used shall be specified by the manufacturer.
5.11.2 Physical sampling efficiency
The physical sampling efficiency can be measured as a function of particle aerodynamic diameter and
other influent parameters. For bioaerosol samplers the physical sampling efficiency which corresponds
to the (size-selective) sampling efficiency should comply with EN 13205, where applicable.
When assessing the performance of any bioaerosol sampler, the overall sampling efficiency (see A.2,
item c)) shall be determined.
The performance of a personal sampler is affected by the proximity of the operator's body when worn
within the breathing zone. This needs to be taken into account when assessing that performance. See A.2.
NOTE Annex A gives some information about the physical behaviour of a sampler and the experimental
assessment of its physical sampling efficiency in the laboratory.
5.11.3 Biological preservation efficiency
To determine the culturable number of microorganisms, the sampler shall be tested with relevant
microorganisms to establish the biological preservation efficiency. The ability of the sampling medium to
maintain the integrity of the sampled microorganisms shall be known.
5.12 Functional range of concentration
The manufacturer shall give the upper and lower functional range for the concentration of collected
culturable microorganisms and/or the total number of microorganisms.
The manufacturer shall specify the maximum sampling time or the sampling volume that can be sampled
without recharging battery-operated samplers or replacing the collection substrate.
NOTE The sampling time can vary from a few minutes up to an 8 h workshift.
5.13 Loading of the sampler
The sampler shall be loaded, emptied and reloaded easily with aseptic collection substrates at the
workplace with a minimum loss of collected bioaerosol.

SIST EN 14583:2022
EN 14583:2021 (E)
5.14 Cleaning of the sampler
The sampler shall be constructed in such a way that cleaning and decontamination in the field can be
done easily and disinfection in the laboratory is possible.
If required for biosecurity or contamination control purposes, samplers shall be resistant to
decontamination by surface disinfection or fumigation, e.g. by using hydrogen peroxide vapour.
5.15 Additional requirements
When possible, battery-operated samplers should have a short recharge time.
All samplers should be light-weighted and have low noise levels.
6 Requirements for testing of biological preservation efficiency of volumetric
bioaerosol samplers
6.1 General
The test conditions applied shall be within the operational range of the sampler as specified by the
manufacturer.
The risk class to which the microbial model organisms belong to shall be compatible with the level of
safety of the test facility and the training of the operators so that microbial model organisms are handled
under optimum safety and health protection conditions.
For the purpose of testing the performance of samplers, the tests shall be carried out on at least two
replicate samplers and compared to the performance of a reference sampler.
The biological preservation efficiency itself cannot be determined as the actual concentration cannot be
measured without any bias. In practise, bioaerosol samplers are compared to each other to show
differences with regard to their biological preservation efficiency.
6.2 Test facility
The biological performance of the bioaerosol samplers shall be studied in a test facility into which specific
aerosols of microorganisms can be generated in suitable conditions (see Annex B). The ratio between the
concentration of microorganisms measured by the sampler to be tested and the concentration assessed
by the reference sampler shall be calculated by using representative microorganisms (see Annex C).
The reference sampler shall comply with the requirements given in EN 13098:2019, 6.2.2.
6.3 Test particles
6.3.1 Concentration range
The test environment shall consist of single particles as well as aggregates of particles in an atmosphere
with controllable relative humidity and temperature. The concentration range of particles within which
the sampler is evaluated shall be given. The temperature and relative humidity of the test environment
shall be stated.
Restrictions on the usability of the sampler in terms of temperature and relative humidity shall be
specified by the manufacturer.
6.3.2 Production of test bioaerosol
Microbial cell suspensions shall be controllably aerosolised and homogeneously mixed in a test facility at
selected temperature and relative humidity. The particle size shall be specified.
10

---------------------- Page: 12 ----------------------
SIST EN 14583:2022
EN 14583:2021 (E)
The microbial model organisms (see Annex C) and media used for their growth shall be specified and
should be appropriate to the end use of the sampler. The microbial strains shall be available from a
standard culture collection (i.e. ATCC, CCUG, NCTC, CBS, DSMZ).
NOTE Microbial model organisms can be cultivated in liquid, solid or semisolid culture media. The bioaerosol
can be generated from water or selected buffer solutions. This can change the surface characteristics of the
bioaerosol particles. Spore aerosols can also be generated from dust or powder. See references [8] to [11].
6.4 Environmental conditions
6.4.1 General
Samplers need to perform optimally in typical ambient environmental conditions. Tests therefore shall
be carried out to determine the impact of variations in air temperature, air pressure, and relative
humidity conditions on flow rate and sampled air volume.
The tests shall be performed inside a test facility, with controlled temperature and relative humidity. A
separate enclosure can be needed for the tests with a variable air pressure. Sufficient replicates of each
combination of temperature and relative humidity conditions used shall be tested to determine statistical
significance. The environmental conditions shall be monitored during sampling time. The mean of each
measured variable and its standard deviation shall be calculated. The results of the tests shall be given in
the test report and the operating conditions shall be documented.
6.4.2 Temperature
The tests shall be carried out at specified temperatures. At least two different conditions of temperature
(for example, about 10 °C and 25 °C) shall be used to cover the range as expected to be used by the
sampler.
6.4.3 Relative humidity
The tests shall be carried out at least at two different conditions of relative humidity (for example, at
about 20 %, 50 % and 80 %, if achievable) for each temperature used in 6.4.2.
6.4.4 Experimental conditions for measuring the physical sampling efficiency of bioaerosol
samplers
The experimental conditions for measuring the physical sampling efficiency of bioaerosol samplers
should be the same as those that are described in EN 13205. However, when bioaerosol samplers are only
designed to measure microorganisms and not microbial compounds, the calculation of uncertainty (of
measurement) relative to mass concentration is not required.
6.5 Stabilization time
For the purposes of the tests in each instance where the sampler is subjected to different test conditions,
the sampler shall be allowed to stabilize.
Maximum time for stabilization should not exceed 30 min.
6.6 Orientation
The manufacturer shall state in which orientations the sampling heads or inlets have been tested relative
to the bioaerosol air-stream and the test environment used (e.g. wind tunnel or test chamber). The
personal samplers shall be tested on a manikin.
When testing samplers in a wind tunnel, they should be tested in the test environment within the
orientation limits stated in the manufacturer's instruction manua

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 1540, EN 13098 and the
following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at http://www.electropedia.org/
3.1
accuracy
closeness of agreement between a test result or measurement result and the true value
Note 1 to entry: In practise, the accepted reference value is substituted for the true value.
Note 2 to entry: The term “accuracy”, when applied to a set of test or measurement results, involves a
combination of random components and a common systematic error or bias component.
Note 3 to entry: Accuracy refers to a combination of trueness and precision.
Note 4 to entry: The quantity referred to in this document as accuracy provides an estimation of the range
around the measured value in which can be found the accepted reference value with the confidence of 95 %.
[SOURCE: ISO 3534-2:2006, 3.3.1, modified – All cross references have been removed and Note 4 to
entry has been added.]
3.2
bias
measurement bias
difference between the expectation of a test result or measurement result and a true value
Note 1 to entry: Bias is the total non-random error as contrasted to random error. There can be one or more
non-random error components contributing to the bias. A larger systematic difference from the true value is
reflected by a larger bias value.
Note 2 to entry: In practice, the accepted reference value is substituted for the true value. The accepted
reference value (for definition see ISO 3534-2) can be, for example, the certified value of a reference material, the
concentration of a standard test atmosphere or the target value of an interlaboratory comparison.
[SOURCE: ISO 3534-2:2006, 3.3.2, modified – Synonymous term “measurement bias” has been added.]
3.3
personal sampler
sampler, attached to a person, that collects gases, vapours or airborne particles in the breathing zone
for the purpose of measuring exposure to chemical agents and/or biological agents
Note 1 to entry: Some sampling devices have integral pumps, and some do not. Where the personal sampler
requires the use of an external pump, the pump is not subject to the requirements of this document.

6 Testing of sampling devices
6.1 General
The test conditions applied shall be within the operational range of the sampling device as specified by
the manufacturer.
The risk class to which the test microorganisms belong to shall be compatible with the level of safety of
the installations and the training of the operators so that surrogates are handled under optimum safety
and health conditions.
NOTE For the assessment of sampler performance for measurement of airborne particle concentrations, see
EN 13205.
For the purpose of testing the performance of sampling devices, the tests shall be carried out on at least
two replicate sampling devices and compared to the performance of a reference sampling device.
6.2 Test facility
The biological performance of the bioaerosol sampling devices shall be studied in a test facility into
which specified aerosols of microorganisms can be generated in suitable conditions (see Annex B). The
ratio between the concentration of microorganisms measured by the sampling device to be tested and
the concentration assessed by some reference sampler shall be calculated by using representative
microorganisms (see Annex C).
6.3 Test particles
6.3.1 Concentration range
The test environment shall consist of single particles as well as aggregates of particles in an atmosphere
with controllable relative humidity and temperature. The concentration range of particles within which
the sampling device is suitable shall be given. The temperature and relative humidity of the test
environment shall be stated.
Limitations in temperature and relative humidity for the sampling device shall be given by the
manufacturer.
6.3.2 Production of test bioaerosol
Microbial cell suspensions shall be controllably aerosolised and homogeneously mixed in a test facility
at selected temperature and relative humidity. The particle size shall be specified.
The test organisms (see Annex C) and media used for their growth shall be specified and should be
appropriate to the end use of the sampling device. The test strains shall be available from a standard
culture collection (i.e. ATCC, CCUG, NCTC, CBS, DSMZ).
NOTE Test bioaerosols can be produced from cultivations in liquid or semisolid culture media, water, or from
selected buffer solutions. This can change the surface characteristics of the bioaerosol particles. Spore aerosols
can also be generated from dust or powder.

prEN 14583:2020 (E)
6.4 Environmental conditions
6.4.1 General
Sampling devices need to perform optimally in typical ambient environmental conditions. Tests
therefore shall be carried out to determine the impact of variations in air temperature, air pressure, and
relative humidity conditions on flow rate and sampled air volume.
The tests shall be performed inside a test facility, with controlled temperature and relative humidity. A
separate enclosure can be needed for the tests with a variable air pressure. Sufficient replicates of each
combination of temperature and relative humidity conditions used shall be tested to determine
statistical validity. The sampled air volume or representative values of sampling time shall be measured
for all predetermined values. The mean of each measured variable and its standard deviation shall be
estimated. The results of the tests shall be given in the test report and the operating conditions shall be
documented.
6.4.2 Temperature
The tests shall be carried out at specified temperatures. At least two different conditions of temperature
(for example, about 10 °C and 25 °C) shall be used to cover the range as expected to be used by the
sampling device.
6.4.3 Relative humidity
The tests shall be carried out at two different conditions of relative humidity (e.g. at about 20 % and
50 % RH) for each temperature used in 6.4.2.
6.4.4 Experimental conditions for measuring the physical sampling efficiency of bioaerosol
sampling devices
The experimental conditions for measuring the physical sampling efficiency of bioaerosol sampling
devices shall be the same as those that are described in EN 13205. However, when bioaerosol sampling
devices are only designed to measure microorganisms and not microbial compounds, the calculation of
bias and accuracy relative to mass concentration is not required.
6.5 Reference sampling device
The reference sampling device used shall be well characterized and the samples shall be taken to allow
analysis of both, the culturable number and total number of microorganisms (see EN 13098). If
appropriate, two different reference sampling devices may be used.
6.6 Stabilization time
For the purposes of the tests in each instance where the sampling device is subjected to different test
conditions, the sampling device shall be allowed to stabilize.
Maximum time for stabilization should not exceed 30 min.
