A Brief Analysis of the Four Major Tests of Automotive Interiors

Brief Analysis of the Four Major Tests of Automotive Interiors

Automotive interior testers include many types, and the general inspection of automotive interior parts generally includes 4 items: odor level test, formaldehyde content test, atomization test, VOC tests, these four commonly used test items can be divided into many subtle test items. This article summarizes a simple analysis of the four main categories.

Fog test

Automotive interior decoration materials such as leather, plastic, textiles and adhesives for bonding materials, etc. ., all contain volatile substances, especially under the sun, the temperature inside the car will rise, which will aggravate this volatilization. Volatile gases condense on car windows or windshields, causing poor vision and affecting sight and vision.a driver’s 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 perform fogging tests on materials used for automotive interiors. Materials whose fogging values ​​exceed standard indicators cannot be used for automobile interiors.

Generally, the atomization test uses the gravimetric method or the gloss method. 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 GB241 0.

Smell test

Odor is a sensation caused by substancesbvolatile substances in the central nervous system which stimulates the olfactory nerve of the human nasal cavity, which can directly reflect the car interior parts quality is based on subjective evaluation of human sense of smell and comfort. Different substances produce different smells. Some flavors are pleasant and some 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. Now, all major manufacturers have their own odor detection methods and standards, such as: Volkswagen vw50180, Volkswagen PV3900, Chery Q/SQR.04.103-2004.

Formaldehyde content test

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

VOC and TVOC Test

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

TVOC: short for Total Volatile Organic Components
