Project Introduction

Preventing air pollution in cars and improving air quality in cars are new issues facing the development of automotive technology today. It is reported that the limit value of air pollutants in cars will be released soon, and the problem of internal pollution in cars has become a hot spot for consumers. Sometimes there are some unknown odors in the car, even the instruments can not be recognized, so there is an industry test project in the automobile manufacturing industry-odor test.

Odor (odor) refers to all the odors emitted by automobile interior parts, which can intuitively reflect the quality of automobile 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, while some of the more smelly gases are not necessarily harmless. The odor in the car has now become a consideration when buying a car. Therefore, the car manufacturer requires its suppliers to carry out odor tests on materials and parts to ensure that the odor in the car does not cause consumer annoyance.

Standard reference

The interior of a modern car contains many different materials, such as plastic. It also contains many chemical substances. Although most of these substances are "enclosed" within the material, a small amount will evaporate, forming the typical smell of new cars. Various world-renowned automobile companies have developed their own corporate standards to monitor these substances and their possible odor in the cabin. In order to create a healthy interior and exterior environment for everyone, companies have launched their own odor test 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
