DIN ISO 12219-3:2011-06 - Draft

This part of ISO 12219 describes a fast, qualitative and quantitative screening method for vapour-phase volatile organic compounds released from vehicle trim materials under simulated real use conditions using micro-scale test chambers. This method is intended for evaluating new car interior trim components but can, in principle, be applied to used car components also. The principle of the test is to determine the area (or mass) specific emission rate of VOCs emitted from automotive products. The test is performed in a micro-scale test chamber at a constant temperature and flow rate. The surface area (or mass) of the sample in the micro-scale test chamber is constant and by measuring the mass or vapour-phase concentrations of emitted compounds, the area (or mass) specific emission rates of VOCs from the product under test can be determined at a given time, t. 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 (2,4-DNPH) sorbent tubes followed by high performance liquid chromatography (HPLC) analysis with ultraviolet absorption for the determination of formaldehyde and other carbonyls (according to ISO 16000-3). This part of ISO 12219 is therefore complementary to existing standards and provides third party test laboratories and manufacturing industry with a cost-effective approach for: - monitoring and screening VOC emissions as part of routine quality control; - monitoring product uniformity / conformity in-between formal certification tests; - comparing emissions from products within a range (e. g. different colours/patterns); - evaluating prototype, "low-emission" materials/products during development.
