ISO 12219-9:2019(E)
Introduction

Volatile organic compounds (VOCs) are widely used in industry and can be emitted by many every-day

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

on cabin 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. Therefore, it is important to get comprehensive and reliable information about the types of

organic compounds in the interior air of vehicles and also their concentrations.

This document outlines the sampling bag test method of volatile organic compounds (VOC),

formaldehyde and other carbonyl compounds which diffuse from vehicle interior parts into the air

inside road vehicles.

Measuring VOC 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.), chambers/bags that have sufficient volume to

house the complete assembly are employed. Meanwhile, to obtain diffusion data from representative

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

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

complementary approach.

the chromatogram in that analytical window to a nominal mass using the chromatographic response

factor for toluene (toluene equivalents)
[SOURCE: ISO 16000-6:2011, 3.4, modified —Note has been deleted.]
4 Principle

The test method specified in this document describes a procedure for calculating sampling bag values

of VOC, formaldehyde and other carbonyl compounds which can diffuse from vehicle interior parts.

Vehicle interior parts put in a sampling bag are heated at a specified temperature, and 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 bag blank concentrations, the sampling bag values of VOC,

formaldehyde and other carbonyl compounds diffusing from vehicle interior parts 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 volatile organic compounds

3 3

(VOCs) ranging in concentration from sub-µg/m to several mg/m . The method is applicable to the

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

6 16

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

3 3

determination of carbonyls within the concentration range of approximately 1 µg/m to 1 mg/m .

5 Apparatus and materials
5.1 General

Test apparatus and materials necessary for determining the sampling bag values of VOC, formaldehyde

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

— sampling bag;
— nitrogen gas or air (filling gas);
2 © ISO 2019 – All rights reserved
---------------------- Page: 7 ----------------------
ISO 12219-9:2019(E)
— thermostatic oven;
— pumps;
— integrating flow meter;
— analytical equipment is described in ISO 16000-3 and ISO 16000-6.
5.2 Large sampling bag
5.2.1 General

Large sampling bags used in this document shall be in accordance with 5.2.2, 5.2.3, 5.2.4 and 7.2.

They shall be low-emitting, low-permeable and low-sorption plastic bags having a capacity of 20 l to

2 000 l used for measuring VOC, formaldehyde and other carbonyl compounds which can emit from

vehicle interior parts. The size of the bag depends on the size of the part and is to be agreed upon

between the parties.
5.2.2 Material

Though no specification is set for the material of a sampling bag, the recommended materials are

fluorinated resin [vinyl fluoride (PVF), polyvinylidene fluoride (PVDF), 4 ethylene fluoride - 6 propylene

fluoride copolymer (FEP)], ethylene-vinyl alcohol copolymer (EVOH). Large sample bags made of just

a single layer of polyethylene terephthalate (PET) or polyolefins (PEHD) can have high permeation

through the bag material. Total film thickness should be above 20 microns.
5.2.3 Air tightness

The large sampling bag shall be sealed airtight using a sealing material such as a tape that will not

affect the test or by the heat seal method so that the gases inside are not mixed with any uncontrolled

outside air.
5.2.4 Bag blank concentration

The bag blank concentration generated by heating a large sampling bag filled with only nitrogen or

air shall be at such a low level as to not affect the test. Each target VOC, collecting 1 l on the sampling

tube, shall have a value less than 20 ng collected on each tube and for formaldehyde and/or any other

carbonyl compound, collecting 3 l on the DNPH cartridge, shall have a value less than 200 ng collected

on each cartridge.

Users should be aware that TVOC bag blank values from bags vary significantly depending on material,

age, cleaning procedure and analytical process. Report specific bag cleaning parameters and all

analytical conditions and calculation methods in order to interpret TVOC report values.

4 Principle

The test method specified in this document describes a procedure for calculating sampling bag values

of VOC, formaldehyde and other carbonyl compounds which can diffuse from vehicle interior parts.

Vehicle interior parts put in a sampling bag are heated at a specified temperature, and 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 bag blank concentrations, the sampling bag values of VOC,

formaldehyde and other carbonyl compounds diffusing from vehicle interior parts 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 volatile organic compounds

3 3

(VOCs) ranging in concentration from sub-µg/m to several mg/m . The method is applicable to the

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

6 16

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

3 3

determination of carbonyls within the concentration range of approximately 1 µg/m to 1 mg/m .

5 Apparatus and materials

Introduction

Volatile organic compounds (VOCs) are widely used in industry and can be emitted by many every-day

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

on cabin 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. Therefore, it is important to get comprehensive and reliable information about the types of

organic compounds in the interior air of vehicles and also their concentrations.

This document outlines the sampling bag test method of volatile organic compounds (VOC),

formaldehyde and other carbonyl compounds which diffuse from vehicle interior parts into the air

inside road vehicles.

Measuring VOC 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.), chambers/bags that have sufficient volume to

house the complete assembly are employed. Meanwhile, to obtain diffusion data from representative

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

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

complementary approach.

Part 9:
Determination of the emissions of volatile organic
compounds from vehicle interior parts — Large bag method
1 Scope

This document specifies a large bag sampling method for measuring volatile organic compounds

(VOCs), formaldehyde and other carbonyl compounds which are emitted from vehicle interior parts

into the air inside road vehicles. This method is intended for evaluation of large new vehicle interior

parts, and complete assemblies. This is a screening method to compare similar car components under

similar test conditions on a routine basis.

Evaluating VOC emissions of vehicle interior parts is an important aspect of the vehicle indoor air

quality.

This document is complementary to existing standards and provides test laboratories and the

manufacturing industry with a cost-effective evaluation of vehicle interior parts. This method is only

applicable to newly manufactured vehicle parts. This method is applicable to all types of vehicles, and

vehicle products which are used as parts in the interior of vehicles.
