Odor testing
Preventing and controlling air pollution and improving the air quality inside the vehicle are new topics of the development of automobile technology today and also become a hot spot for consumers.
Odor refers to all the odors emitted by automotive interior parts. It can intuitively reflect the quality of automotive interior parts based on the subjective evaluation of human sense of smell and comfort. It should be noted that some of the more unpleasant gases are not necessarily harmful as well ad some of the pleasant gases are not necessarily harmless. The smell in the car has now become a consideration when buying a car. Therefore, the car manufacturers require its suppliers to conduct odor testing on materials and components to ensure that the smell in the car does not make consumer disgusted.
The main source of odor inside the car:
- Dashboard
- sun-shading board
- Car canopy
- Door Trim Panel
- Coat rack assembly
- Luggage trim
- sealing strips
- Seat assembly
- Carpet assembly
- foot pad
- Steering wheel
QC can test the smell of the components and materials in the car according to different series of standards of each brand.
Involved standards: VDA 270, PV 3900, GMW 3205, SAE J1351, SMTC 5400012, BO131-03, TSM 0505G etc.
fogging testing
The fogging/condensate component is the condensation of volatile materials discharged from automotive interior components and materials onto the glass. Automotive interior materials such as leather, plastics, textiles and adhesives for bonding materials contain some volatile substances, especially under the illumination of sunlight, the temperature inside the car rises, which will accelerate volatilization and some volatile substances will harm human body. In order to properly control the production of volatile substances, it is necessary to conduct fogging testing on materials used in automotive interiors.If the fogging value exceeds the stipulated standard,it will not be used in automotive interiors.
QC can provide you with fogging testingg services according to the following standards and the test methods involved:

Asbestos testing
Asbestos is a harmful substance in the air pollutants of many car vehicles that has a relatively hidden but very harmful impact on human health. Asbestos is a material with high fire resistance, electrical insulation and thermal insulation, so it is an important fireproof, insulating and thermal insulation material. However, asbestos fibers can cause asbestosis, pleural mesothelioma and other diseases, that’s why many countries have chosen to ban the use of this dangerous substance.
In the production of automobiles, if the brake components are used with asbestos raw materials , it will release the asbestos fibers when the temperature increased by friction during the braking process , which not only pollutes the atmosphere, but also enters the human body through the respiratory tract, as a result it will eventually cause serious harm. At present, the requirements of domestic car companies for asbestos testing are very strict, and each car company also collates its own requirements to sort out the relevant testing standards as one of the access conditions for component suppliers.
According to the existing domestic and international standards and literature methods, asbestos testing can be divided into polarized light microscopy (PLM), X-ray diffraction (XRD), scanning electron microscopy / energy spectroscopy (SEM / EDS), phase contrast microscopy (PCM), Infrared spectroscopy (IR) etc. The relevant testing standards are mainly based on GB/T 23263-2009 and ISO 22262-1:2012.
QC can provide you with professional asbestos testing services according to different regulations or testing methods.
Reliability testing
The environmental testing targets the adaptability of the product to the expected working environment; The reliability testing is a test designed and improved according to reliability requirements under typical environmental conditions.
