Odor Test
Project Introduction
Preventing and controlling air pollution in the car and improving and purifying the air quality in the car are new issues facing the development of automobile technology at home and abroad. It is reported that the limit value standard of air pollutants in the car will be issued soon, and the problem of pollution in the car has become a hot topic of general concern to consumers. Sometimes there are some peculiar smells of unknown origin in the car, which cannot be identified even by instruments. Therefore, there is an industry test project in the automobile manufacturing industry-odor test.

Odor refers to all odors emitted by car interior parts, which can directly reflect the quality of car interior parts and is based on the subjective evaluation of human sense of smell and comfort. It should be noted that some gases with bad smells may not be harmful, and some gases with good smells may not be harmless. The odor in the car has now become a consideration for car buyers when choosing a car, so car manufacturers require their suppliers to conduct odor tests on materials and parts to ensure that the odor in the car does not cause disgust among consumers.

Standard Reference
The interior of modern cars contains many different materials, such as plastics. Among them, there are many chemical substances. Although most of these substances are "enclosed" in the materials, a small amount will still evaporate, forming the typical smell of new cars. Each of the world's leading automobile companies has developed its own corporate standards to monitor these substances and the odors they may create in the vehicle cabin. In order to create a healthy in-car and out-car environment for everyone, various companies have launched their own odor test standards, such as:
· Volkswagen vw50180
· Volkswagen PV3900
· Chery Q/SQR.04.103-2004
· GM GME60276
· Toyota TSM0505G
· German Association of the Automotive Industry VDA270
· Volvo VCS1027,2729
