Introduction

Volatile organic compounds (VOCs) are widely used in industry and may be emitted by many everyday

products and materials. They have attracted much attention in recent years because of their impact on indoor

air quality. After homes and workplaces, people spend a lot of time in their vehicles. It is important to determine

the material emissions of interior parts and to reduce them to an acceptable level, if required. Therefore it is

necessary to obtain comprehensive and reliable information about the types of organic compounds in the

interior air of vehicles and also their concentrations.

This part of ISO 12219 outlines the sampling bag test method for the screening of VOCs, formaldehyde and

other carbonyl compounds which diffuse from vehicle interior parts into the air inside road vehicles.

Measuring VOCs from vehicle interior parts can be performed in several ways and the approach selected

depends upon the desired outcome and the material type. For example, to obtain diffusion data from complete

assemblies (e.g. instrument panel, seat etc.) it is necessary to employ chambers / bags that have sufficient

volume to house the complete assembly. Meanwhile, to obtain diffusion data from representative samples of

homogeneous vehicle interior materials, the micro-scale chamber method can be chosen.

Each measurement method such as bag/micro-scale chamber/small-chamber sampling offers a

complementary approach.

and quantified by converting the total area of the chromatogram in that analytical window to toluene equivalents

NOTE Adapted from ISO 16000-6:2011, 3.4.
4 Principle

The test method specified in this part of ISO 12219 is a procedure for calculating sampling bag values of VOCs,

formaldehyde, and other carbonyl compounds which may diffuse from vehicle interior parts.

One or multiple test specimens put in a sampling bag are heated to a specified temperature, then a fraction of the

gas in the sampling bag is collected to measure the test concentrations. By comparing the test concentrations

with the corresponding blank concentrations, the sampling bag values of VOCs, formaldehyde, and other

carbonyl compounds diffusing from one test specimen can be calculated (see Clause 10).

The analytical part of the overall measurement procedure is based on the use of sorbent tubes with subsequent

thermal desorption and gas chromatographic analysis for VOCs (according to ISO 16000-6) and the use of

2,4-dinitrophenylhydrazine (DNPH) sorbent tubes, followed by high performance liquid chromatography (HPLC)

analysis with ultraviolet absorption for the determination of formaldehyde and other carbonyl compounds

(according to ISO 16000-3).

The specified analytical procedure is valid for the determination of VOCs ranging in concentration from sub-

microgram per metre cubed to several milligrams per metre cubed. The method is applicable to the measurement

of non-polar and slightly polar VOCs ranging in volatility from n-C to n-C .

The specified analytical procedure for formaldehyde and other carbonyl compounds is valid for the determination

3 3

of carbonyl compounds within the concentration range of approximately 1 µg/m to 1 mg/m .

5 Apparatus and materials

5.1 General. The test apparatus and materials necessary for determining the sampling bag values of VOCs,

formaldehyde and other carbonyl compounds diffusing from vehicle interior parts are mainly as follows:

4 Principle

The test method specified in this part of ISO 12219 is a procedure for calculating sampling bag values of VOCs,

formaldehyde, and other carbonyl compounds which may diffuse from vehicle interior parts.

One or multiple test specimens put in a sampling bag are heated to a specified temperature, then a fraction of the

gas in the sampling bag is collected to measure the test concentrations. By comparing the test concentrations

with the corresponding blank concentrations, the sampling bag values of VOCs, formaldehyde, and other

carbonyl compounds diffusing from one test specimen can be calculated (see Clause 10).

The analytical part of the overall measurement procedure is based on the use of sorbent tubes with subsequent

thermal desorption and gas chromatographic analysis for VOCs (according to ISO 16000-6) and the use of

2,4-dinitrophenylhydrazine (DNPH) sorbent tubes, followed by high performance liquid chromatography (HPLC)

analysis with ultraviolet absorption for the determination of formaldehyde and other carbonyl compounds

(according to ISO 16000-3).

The specified analytical procedure is valid for the determination of VOCs ranging in concentration from sub-

microgram per metre cubed to several milligrams per metre cubed. The method is applicable to the measurement

of non-polar and slightly polar VOCs ranging in volatility from n-C to n-C .

5.2 Sampling bag.

5.2.1 General. Sampling bags used in this part of ISO 12219 shall be in accordance with 5.2.2, 5.2.3,

5.2.4 and 7.2.

5.2.2 Material and capacity. The sampling bag material shall be inert, impermeable, and non-sorbing [e.g.

fluorinated resins, such as poly(vinyl fluoride) (PVF) or perfluoro(ethylene/propylene) plastic] and shall meet the

performance characteristics specified in 7.2. The bag capacity shall be at least 10 l.

5.2.3 Airtightness. Sampling bags shall be sealed securely with low-emitting tape or heat bonded so as to

be isolated from the uncontrolled ambient air.

5.2.4 Blank concentration. Blank concentrations (background artefacts) which are observed when a

sampling bag is heated to test temperature (65 °C) without any sample present, shall be as low as possible (e.g.

below 0,075 µg/bag for formaldehyde and other carbonyl compounds and below 0,05 µg/bag for VOCs) so that

they do not interfere with the test results.

5.3 Purity of the gas. The nitrogen gas or air introduced to the sampling bag shall be pure and dry. The

concentrations of VOCs, formaldehyde and other carbonyl compounds shall be as low as possible so that they

do not adversely affect the test results.

The purity of the gas or air shall fulfil the requirements of ISO 16000-3 and ISO 16000-6.

5.4 Thermostatic oven. Temperature shall be controlled in an oven which is capable of maintaining a

constant and homogeneous temperature.

The thermostatic oven where a sampling bag is heated shall be capable of uniformly controlling temperatures

within ±1 °C.

5.5 Pumps. Vacuum pumps or other apparatus which can be used to evacuate sampling bags sufficiently

quickly shall be used.

5.6 Integrating flow meter or gas meter. The volume of sampled gases or other gases shall be measured

and adjusted to standard conditions (23 °C and 101,3 kPa) with an integrating flow meter or a gas meter (V ±

0,1 l, where V is volume).

5.7 Gas analyser. VOC analysis shall be performed according to ISO 16000-6 using thermal desorption

(TD) and a gas chromatograph equipped with a mass spectrometer (GC–MS) and an optional flame ionization

detector (FID). A high performance liquid chromatograph (HPLC) shall be used for the analysis of formaldehyde

and other carbonyl compounds.
