Renault D49 3027 Determination of Volatile Organic Emissions - Room Test

The “Renault D49 3027 Determination of volatile organic emissions - Room test” standard developed by the French automobile company Renault describes a test method for the analysis of volatile organic compounds (VOCs) produced from cabin parts.

VOC emission test chambers located in advanced laboratories enable the characterization of volatile organic compound emissions under sensitive testing conditions. They are fully compliant with the requirements of common European and international standards as well as specific manufacturers' standards. Used for high accuracy testing in the automotive industry, the 1 m3 VOC emission test chambers are fully compliant with ISO 12219-4 and VDA 276 standards and meet all requirements of various manufacturer standards, including the Renault D49 3027 standard.

In the "ISO 12219-4 Internal air of road vehicles - Part 4: Method for determination of emissions of volatile organic compounds from vehicle interior parts and materials - Small chamber method" standard developed by the International Organization for Standardization (ISO), real use conditions are simulated using small emission test chambers. describes a qualitative and quantitative analytical test method for vapor phase organic compounds (volatile and some semi-volatile) released from car wrapping materials. The small chambers are intended to provide a transfer function to vehicle-level emissions. This method is designed to evaluate new car interior trim components, but in principle it is also applied to used car components.

The standard "VDA 276 Determination of the proportion of high-source components in Ottockraft material by gas chromatography" developed by the German Automotive Industry Association (VDA) describes a test method for the determination of organic substances emitted from automotive interior products using a 1 m3 test cabin.

Target compounds in automobiles include volatile organic compounds (VOCs) and volatile carbonyl compounds such as formaldehyde. Volatile organic compounds are generally organic compounds in the volatility range of n-hexane to n-hexadecane.

The Renault D49 3027 standard provides third-party testing laboratories and the manufacturing industry with an approach to:

• Determining the impact of actual use conditions on specific volatile organic compound emissions data
• Comparison of emissions from various compounds in terms of specific volatile organic compound emissions
• Evaluation and classification of specific assemblies for specific volatile organic compound emissions data
• Provision of specific volatile organic compound emission data to develop and validate a correlation between material level methods and vehicle level method
• Evaluation of prototype, low-emission assemblies during development

Generally, the VOC emission test chamber size is one cubic meter. All relevant standards specify that the test chamber volume must be one cubic meter, but exact dimensions for width, depth and height are not given. Test chambers designed according to special requirements are mainly used to study the emission change rules of volatile organic compounds (VOCs) in wood products, furniture, floors, carpets, construction and decoration materials and related light industrial products. Meanwhile, the VOC emission chamber also detects the amount of formaldehyde and VOCs released in building materials, furniture, automobile interior accessories, electrical appliances and other products.

Generally, the VOC emission test chamber is controlled by color touch screen, which can realize the display, setting, modification, storage and other functions of equipment parameters. It is necessary to adjust the temperature in the test area, the relative humidity in the test area, the fresh air flow rate, the ventilation rate, the automatic start time and the cumulative operating time.

Among the numerous testing, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides room test services for the determination of volatile organic emissions within the scope of the Renault D49 3027 standard, with a trained and expert staff and advanced technological equipment.
