Four major tests of automobile interior parts

Testing of automobile interior parts generally includes 4 items: odor level test, formaldehyde content test, fogging test, VOC test

Smell test:

Smell is a sensation caused by volatile substances in the central nervous system by stimulating the nerve olfactory of the human nasal cavity, which can directly reflect the car. the quality of interior rooms is based on a subjective assessment of smell and human comfort. Different substances produce different smells. Some flavors are pleasant and others are disgusting. Odor is a global sensation, characterized by the concentration of odor and the nature of odor. Therefore, many car manufacturers use the quality of smell to assess whether their parts will offend customers. From now on, all the major manufacturers have theirown odor detection methods and standards, such as: Volkswagen vw50180, Volkswagen PV3900, Chery Q/SQR.04.103-2004. General GME60276, Toyota TSM0505G, German Automobile Industry Association VDA270, Volvo VCS1027,2729

Formaldehyde content test

Formaldehyde is a It is a very powerful polymerizing agent, but formaldehyde has strong toxicity and is very harmful to the human body. Due to the widespread use of formaldehyde, formaldehyde has long been listed as a hazardous substance and has been controlled in various industries. European and American automakers have separate standards for measuring formaldehyde volatilization, while Japanese automakers started late to control harmful substances and included formaldehyde in the VOC testing method.

Atomization test:

Car interior decoration materials such as leather, plastics, textiles and adhesives for bonding materials, etc., all contain volatile substances, especially under the sun, the temperatureThe temperature inside the car will rise, which will worsen this volatilization. Volatile gases condense on car windows or windshields, causing poor vision and affecting the driver\'s eyesight and driving safety; some volatile substances are harmful to the human body and harm the health of drivers and passengers. In order to reasonably control the generation of volatile substances, it is essential to carry out fogging tests on materials used for automotive interiors. Materials whose fogging values ​​exceed the standard indicators cannot be used.for automotive interiors.

The general fog test adopts the gravimetric method or the gloss method, and each car manufacturer has its own internal implementation standards:

Volkswagen PV3015, Chery Q/SQR .04.097-2004, GM GMW3235, Toyota TSM0503G, Nissan NES M0161, British BS AU 168-1978, German DIN75201, American SAEJ1756, Shenlong D45 1727, Mitsubishi ES-X83217, National Standard GB2410

VOC and TVOC test

VOC: I is the English abbreviation of volatile organic compounds (volatile organic compounds), which has a huge impact on the human health. When the VOCs in the confined space reach a certain concentration, people will experience headache, nausea, vomiting, fatigue, etc. in a short time. Serious consequences such as memory loss.

TVOC: the abbreviation for Total Volatile Organic Components
