Introduction
The health of workers in many industries is at risk through exposure by inhalation to airborne particles
generated by welding and allied processes (welding fumes) and other airborne particles generated by
welding-related operations, such as grinding. Industrial hygienists and other public health professionals
need to determine the effectiveness of measures taken to control workers’ exposure to these harmful
substances and this is generally achieved by making personal exposure measurements.
This document is intended to be of benefit to agencies concerned with health and safety at work, industrial
hygienists and other public health professionals, industrial users of welding and allied processes and their
workers, and analytical laboratories.
It has been assumed in the drafting of this document that the execution of its provisions, and the
interpretation of the results obtained, is entrusted to appropriately qualified and experienced people.

3.1.2
breathing zone
space around the nose and mouth from which breath is taken
Note 1 to entry: Technically, the breathing zone corresponds to a hemisphere (generally accepted to be 30 cm
in radius) extending in front of the human face, centred on the midpoint of a line joining the ears. The base of the
hemisphere is a plane through this line, the top of the head and the larynx. This technical description is not applicable
when respiratory protective equipment is used.
[SOURCE: ISO 18158:2016, 2.1.5.5]
3.1.3
exposure
situation in which a chemical agent (3.1.1) or biological agent is present in the air that is inhaled
by a person
[SOURCE: ISO 18158:2016, 2.1.5.1]
3.1.4

OELV
limit of the time-weighted average of the concentration of a chemical agent (3.1.1) in the air within the
breathing zone (3.1.2) of a worker in relation to a specified reference period
Note 1 to entry: Limit values are mostly set for reference periods of 8 h, but can also be set for shorter periods or
concentration excursions. Limit values for gases and vapours are stated in terms independent of temperature and air
pressure variables in millilitres per cubic metre, and in terms dependent on those variables in milligrams per cubic
metre, for a temperature of 20 °C and a pressure of 101,3 kPa. Limit values for airborne particles, as well as mixtures
of particles and vapours, are given in milligrams per cubic metre or multiples of that unit for actual environmental
conditions (temperature, pressure) at the workplace. Limit values of fibres are given in number of fibres per cubic
metre or number of fibres per cubic centimetre for actual environmental conditions (temperature, pressure) at the
workplace.

uncertainty
non-negative parameter characterizing the dispersion of the quantity values being attributed to a measurand

Note 1 to entry: The parameter can be, for example, a standard deviation called standard measurement uncertainty
(or a specified multiple of it), or the half-width of an interval, having a stated coverage probability.
Note 2 to entry: Measurement uncertainty comprises, in general, many components. Some of these can be evaluated
by Type A evaluation of measurement uncertainty from the statistical distribution of the quantity values from series
of measurements and can be characterized by standard deviations. The other components, which can be evaluated
by Type B evaluation of measurement uncertainty, can also be characterized by standard deviations, evaluated from
probability density functions based on experience or other information.

4 Principle
Airborne particles are collected by drawing a known volume of air through a collection substrate, for
example a filter, mounted in a sampler designed to collect the appropriate fraction of airborne particles.
For personal sampling, the sampler is positioned in the operator’s breathing zone. In such instances, it is
necessary to use a mounting arrangement that enables the sampler to be maintained in position in the
operator’s breathing zone throughout the sampling period without impeding normal work activity. Exposure
to airborne particles from welding and allied processes (welding fume) and airborne particles from welding-
ISO 10882-1:2024(en)
related operations can be determined by gravimetric analysis of the sample, if desired. Exposure to specific
chemical agents in welding fume and airborne particles from welding-related operations is determined by
chemical analysis of the sample.
5 Requirement
Procedures used for assessment of personal exposure to welding fume and other airborne particles
generated by welding-related operations shall meet the requirements of EN 482.
6 Equipment
6.1 Sampling equipment
6.1.1 Samplers, designed to collect the relevant health-related fraction of airborne particles, as defined in
ISO 7708, conforming to the provisions of EN 13205-1 over the particle size range relevant for welding fume
and airborne particles generated by welding-related operations. See 9.1 for selection of samplers.
NOTE 1 Some inhalable samplers are designed to collect the inhalable fraction of airborne particles on the
collection substrate, so that any particulate matter deposited on the internal surfaces of the sampler is not of interest.
Other inhalable samplers are designed such that airborne particles which pass through the entry orifice(s) match the
inhalable convention, in which case particulate matter deposited on the internal surfaces of the sampler does form
part of the sample. (Samplers of this second type generally incorporate a sampling cassette that can be removed from
the sampler to enable this material to be easily recovered.) The operating instructions supplied by the manufacturer
generally state whether particulate matter deposited on the internal surfaces of the sampler forms part of the sample.
NOTE 2 In general, personal samplers for collection of the inhalable fraction of airborne particles do not exhibit the
same size-selective characteristics if used for fixed-point sampling.
6.1.2 Equipment for mounting samplers in the operator’s breathing zone, in the manner prescribed
in 9.3.1.
6.1.3 Collection substrates, suitable for use with the samplers (6.1.1), with a collection efficiency
of not less than 99,5 % for particles with a 0,3 µm diffusion diameter (see ISO 7708:1995, 2.2, Note), and
manufactured from a material that is compatible with the sample preparation and analysis method. See
Reference [20] for information on collection efficiency of filters.
The collection substrates used in the gravimetric method described shall be fit for purpose, for example
sufficiently resistant to moisture retention and not excessively friable. See ISO 15767 for further assistance.
If chemical analysis of the sample is to be carried out, the collection substrates shall not be manufactured
from a material that can react with the chemical agents to be determined. See ISO 15202-1 and ISO 16740 for
further assistance.
6.1.4 Sampling pumps, with an adjustable flow rate, capable of maintaining the selected flow rate (see
9.2.3) to within ±5 % of the nominal value throughout the sampling period (see 8.4).
For personal sampling, the pumps shall be capable of being worn by the worker without impeding normal
work activity.
The pump shall have, as a minimum, the following features:
— an automatic control that keeps the volume flow rate constant in the case of a changing back pressure;
— 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;
ISO 10882-1:2024(en)
— a facility for the adjustment of flow rate, such that it can only be actuated with the aid of a tool (e.g.
screwdriver) or requires special knowledge for operation (e.g. via software), so as to preclude inadvertent
readjustment of the flow rate during use;
— a flow rate pulsation that does not exceed 10 % of the flow rate.
An integral timer is a highly desirable additional feature.
NOTE ISO 13137 requires that the performance of the pumps be such that:
— a flow rate set within the nominal range does not deviate by more than ±5 % from the initial value under increasing
back pressure;
— within the range of ambient temperatures from 5 °C to 40 °C, the flow rate measured under operating conditions
does not deviate by more than ±5 % from the target flow rate at 20 °C;
— the operating time is at least 2 h, and preferably 8 h;
— the flow rate does not deviate by more than ±5 % from the initial value during the operating time.
If the sampling pump is used outside the range of conditions specified in ISO 13137, appropriate action shall
be taken to ensure that the performance requirements are met. For instance, at sub-zero temperatures it
can be necessary to keep the pump warm by placing it under the worker’s clothes.
6.1.5 Flow meter, portable, with a measurement uncertainty < 2,5 %.
The calibration of the flow meter shall be checked against a primary standard, i.e. a flow meter whose
accuracy is traceable to national standards. If appropriate (see 9.1.4), the atmospheric temperature and
pressure at which the calibration of the flow meter is checked shall be recorded.
NOTE See the annex of EN 482 for examples of the measurement uncertainty of different flow meters.
6.1.6 Ancillary equipment.
6.1.6.1 Flexible tubing, of a diameter suitable for making a leakproof connection from the samplers
(6.1.1) to the sampling pumps (6.1.4).
6.1.6.2 Belts or harnesses, to which the sampling pumps can conveniently be fixed (except where the
sampling pumps are small enough to fit in an operator’s pockets).
6.1.6.3 Tweezers, flat-tipped, for loading and unloading collection substrates into samplers.
6.1.6.4 Transport cassettes or other suitable containers, to hold collection substrates while they are
conditioned for weighing, if required, and to transport collection substrates to the laboratory.
6.1.6.5 Thermometer, 0 °C to 50 °C, graduated in divisions of 1 °C or better, for measurement of
atmospheric temperature, if required (see 9.1.4).
For applications at temperatures below freezing, the range of the thermometer shall extend to the
appropriate desired range.
6.1.6.6 Barometer, suitable for measurement of atmospheric pressure, if required (see 9.1.4).
6.2 Weighing equipment, if required
6.2.1 Analytical balance, capable of weighing to ±0,01 mg, calibrated with masses traceable to national
standards. The balance shall be set up and operated according to the manufacturer’s instructions and its
calibration shall be checked before use.
ISO 10882-1:2024(en)
6.2.2 Electrostatic charge neutralizer, for dissipation of electrostatic charge during handling of
substrates and weighing. If a radioactive source is used, its recommended useful life shall be observed.
National legislation dealing with maintenance, monitoring and disposal of the source can exist.
7 Assessment strategy
EN 689 gives guidance for the assessment of exposure by inhalation to chemical agents in workplace
atmospheres. The generalized assessment strategy it describes shall be observed. This can involve:
a) an initial appraisal of the likelihood of exposure to airborne particles, for example by using known
information about the process and workplace factors;
b) a basic survey to provide quantitative information about likely exposure, for example by using existing
exposure data from comparable proc
