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

ISO 13199:2012(E)
Introduction
Volatile organic compounds (VOCs) play significant roles in atmospheric chemistry, especially the formation
of photochemical oxidants and/or ozone (O ) and suspended particulate matter (SPM), which are known to
have negative impacts on human health and biological systems. There are many areas of the world where their
atmospheric concentrations are close to or above the level of the WHO guidelines for environmental standards
in each nation. It is therefore strongly required in many nations to reduce the emission of VOC from various
anthropogenic sources.
In order to manage VOC emission from stationary emission sources, it is essential for enterprises to evaluate
the quantity of VOCs emitted from their facilities where organic solvents as well as other chemicals are used
for industrial processes like painting, printing, cleaning, and degreasing.
A technique for continuously and precisely measuring the concentration of total VOCs (TVOCs) in waste
gases emitted from ducts to atmosphere, which is easy to operate and to maintain, is very helpful for both
governments and enterprises to control and reduce VOC emissions. This measurement method, based on
the use of an NDIR analyser equipped with a catalytic converter for oxidation of TVOCs to CO , has some
advantages compared to measurement methods using flame ionization detection (FID) and FID–GC (flame
ionization detection–gas chromatography), namely:
a) high-safety operation is possible, since no flame and no hydrogen are used;
b) response factors of individual VOCs are not different from each other;
c) no interference due to oxygen is observed.
Note, however, that this method is not applicable to waste gas from combustion processes.
INTERNATIONAL STANDARD ISO 13199:2012(E)
Stationary source emissions — Determination of total volatile
organic compounds (TVOCs) in waste gases from non-
combustion processes — Non-dispersive infrared analyser
equipped with catalytic converter
1 Scope
This International Standard specifies the principle, the essential performance criteria and quality
assurance/quality control (QA/QC) procedures of an automatic method for measuring total volatile organic
compound (TVOC) content in waste gases of stationary sources, using a non-dispersive infrared absorption
(NDIR) analyser equipped with a catalytic converter which oxidizes VOC to carbon dioxide.
This method is suitable for the measurement of TVOC emissions from non-combustion processes. This
method allows continuous monitoring with permanently installed measuring systems, as well as intermittent
measurements of TVOC emissions.
The method has been tested on field operation for painting and printing processes, where TVOC concentrations
3 3
in the waste gases were from about 70 mg/m to 600 mg/m .

5 Principle
5.1 Method of measurement
The measuring system consists of a sample conditioning system and the NDIR analyser for measuring CO
equipped with the converter for oxidation of TVOCs to CO as shown in Figure 1. A portion of sample gas (gas
A) passes through the converter (and the moisture removal system), and goes into the NDIR analyser, while
another portion of sample gas (gas B) passes through (the moisture removal system), and goes into the NDIR
analyser. The difference in the CO concentration between gas A and gas B is equal to the concentration of
CO which comes from TVOCs.

ISO 13199:2012(E)
5.2 Analyser equipment
The gas analysers use, as the measurement principle, the absorption of infrared radiation (IR) by the component
measured in characteristic wavelength ranges. The analysers operate according to the non-dispersive IR
(NDIR) method, while the selectivity of measurement is achieved by the radiation detector which is filled with
the component to be measured. Schematic diagrams of a typical NDIR analyser for measuring TVOC mass
concentration are given in Figures A.1, A.2, and A.3.
5.3 Performance criteria fulfilment

approach for uncertainty estimation as specified in ISO 20988. The uncertainty of the measured values under
field operation is not only influenced by the performance characteristics of the analyser itself, but also by
uncertainty contributions due to:
a) the sampling line and conditioning system;

system fulfil the requirements for a maximum allowable expanded uncertainty. This uncertainty budget shall be
drawn up according to the procedures specified in ISO 14956 or ISO 20988, taking into account all the relevant
characteristics included in calculation of expanded uncertainty given in Table 1. An example of the evaluation
of an uncertainty budget is given in Annex D.
7 Measurement procedure
7.1 General
The AMS shall be operated according to the manufacturer’s instructions. The QA/QC procedures specified
in Clause 8 shall be strictly observed. During the measurement, the ambient conditions should be applied in
ranges during the general performance test.
7.2 Choice of the measuring system
To choose an appropriate analyser, sampling line, and conditioning unit, the following characteristics of waste
gases should be known before the field operation:
a) temperature of the waste gas;
b) water vapour content of the waste gas;
c) dust load of the waste gas;
d) expected concentration range of TVOCs;
e) expected concentration of potentially interfering substances.
To avoid long response times and memory effects, the sampling line should be as short as possible. If
necessary, a bypass pump should be used. If there is a high dust loading in the sample gas, an appropriate
heated filter shall be used.
Before conducting field measurements, the user shall verify that the necessary QA/QC procedures have
been performed.
7.3 Sampling
7.3.1 Sampling location
The sampling location chosen for the measurement devices and sampling shall be of sufficient size and
construction in order to obtain a representative emission measurement suitable for the measurement task.
In addition, the sampling location shall be chosen with regard to safety of the personnel, accessibility and
availability of electrical power.
7.3.2 Sampling point(s)
Ensure that the gas concentrations measured are representative of the average conditions inside the waste
gas duct. Therefore, the sampling points shall be selected to allow for a representative sampling.
[2] [6]
NOTE The selection of sampling points for representative sampling is described e.g. in ISO 9096 and EN 15259.
7.4 Data collection
The values measured with the calibrated NDIR analyser under operating conditions of the waste gas shall be
recorded by an internal or external data-logging system and averaged in accordance with the measurement task.

ISO 13199:2012(E)
7.5 Calculation
The TVOC mass concentration at standard conditions is the quotient of the mass of TVOCs to the volume of
the dry gas under specified reference conditions of temperature and pressure (273 K, 1 013 hPa), normally
expressed in milligrams per cubic metre (mg/m ) which is calculated as carbon. Results of the measurement
shall be expressed as mass concentrations at reference conditions of water vapour (dry gas).
If the TVOC concentration is provided as a volume concentration, Equation (1) shall be used to calculate the
mass concentration at standard conditions of temperature and pressure (273 K, 1 013 hPa):

8 Quality assurance and quality control procedures
8.1 General
QA/QC are important in order to ensure that the uncertainty of the measured TVOC values is kept within the
limits specified for the measurement task.
Two different applications of the automatic measuring system require distinction:
— AMS for intermittent measurements;
— permanently installed AMS for continuous monitoring.
8.2 Frequency of checks
Table 2 shows the minimum required frequency of checks. The user shall implement the relevant standards for
determination of performance characteristics or procedures described in Annex C.
The user shall implement a procedure to guarantee that the zero gases and span gases used meet the
uncertainty requirement specified in Annex B, e.g. by comparison with a reference gas of higher quality.
8.3 AMS for intermittent measurements
8.3.1 General
AMS for intermittent measurements shall be adjusted and checked in accordance with 8.3.2 at the frequencies
specified in Table 2.
The results of the QA/QC procedures shall be documented.
8.3.2 Adjustments and functional tests
8.3.2.1 Instrument adjustment
Instrument adjustments with zero and span gases shall be carried out at least at the beginning of each
measurement series. Appropriate safety procedures shall be followed.
ISO 13199:2012(E)
The zero and span gas shall be introduced under the same flow and pressure conditions using the sample port
of the instrument or according to the manufacturer’s instructions when using individual zero and span ports.
The adjustment procedure shall be carried out as follows:
a) feed zero gas into the NDIR analyser and set the zero;
b) feed span gas and adjust the instrument accordingly;
c) feed zero gas into the NDIR analyser once more and check the reading returns to zero.
Steps a) to c) shall be repeated if the reading does not return to zero.
