Description (English):

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.

Abstract

Overview

ISO 12219-9:2019 - Interior air of road vehicles - Part 9 defines the large bag method for measuring emissions of volatile organic compounds (VOCs), formaldehyde and other carbonyl compounds from vehicle interior parts. Intended as a routine screening method, it evaluates large new parts and complete assemblies (e.g., instrument panels, seats) by enclosing them in a low-emitting sampling bag, heating under controlled conditions, sampling the bag air and calculating emitted concentrations (sampling bag values). The method is applicable to all vehicle types and provides a cost‑effective complement to other emission test methods.

Key topics and technical requirements

Scope and purpose: Screening evaluation of new vehicle interior parts and assemblies to assess contribution to vehicle indoor air quality.
Target analytes: VOCs (non‑polar and slightly polar, n‑C6 to n‑C16 range), formaldehyde and other carbonyl compounds.
Principle: Place part in a large sampling bag, heat under specified conditions, collect a fraction of the bag gas, subtract bag blank values and calculate sampling bag values for target compounds.
Sampling bags: Bags must be low‑emitting, low‑permeable and low‑sorption, with capacities typically 20 L to 2 000 L - size chosen relative to the test specimen.
Apparatus: Thermostatic oven (for controlled heating), clean filling gas (nitrogen or air), pumps and integrating flow meter, analytical equipment per referenced standards.
Analytical methods:
- VOCs: Sorbent tubes (e.g., Tenax TA), thermal desorption and gas chromatography per ISO 16000‑6.
- Formaldehyde/carbonyls: DNPH sorbent tubes and HPLC/UV per ISO 16000‑3.
Quality assurance: Bag blank monitoring, recovery checks and reporting requirements are specified to ensure reproducibility and comparability.

Applications and users

Automotive OEMs and suppliers for material selection, supplier evaluation and production quality control.
Independent test laboratories performing routine emissions screening or client testing.
Indoor air quality specialists and regulators assessing cabin air safety and compliance.
Use cases include comparing similar components under standardized conditions, screening production batches, and pre‑selection of low‑emitting materials for vehicle interiors.

Related standards

ISO 16000‑6 - Determination of VOCs in indoor and test chamber air (Tenax TA, thermal desorption + GC).
ISO 16000‑3 - Determination of formaldehyde and other carbonyls (active sampling, DNPH + HPLC).
ISO 12219 series - other parts cover alternate methods and related definitions for vehicle interior air testing.

Keywords: ISO 12219-9:2019, large bag method, VOC emissions, vehicle interior, formaldehyde, carbonyls, sampling bag, automotive emissions testing, indoor air quality.
