Motidization of automotive interior parts refers to the condensation of volatile substances discharged by car interior parts and materials on the glass. Car interior decorative materials such as leather, plastic, textiles, and adhesives that contain some volatile substances. Under the sun, the temperature in the car increases, which will exacerbate this substance volatilization. The volatile gas condenses on the car window or windshield, causing poor sight and affecting the driver's sight. Therefore, in order to ensure driving safety, it is necessary to perform atomization tests for materials used for car interior.
This issue of Shanghai QINSUN will take a look at the atomization test of the car interior part of the car.
As early as the 1970s, some large auto manufacturers in Europe have begun to study the fog characteristics of the interior parts of the car. The combined formation of the fog working group was systematically studied for the reproduction of the test method and method of fog, and in 1992, the corresponding standard DIN75201 Determination of the Windscreen Fogging Characteristics in Motor Vehicles was released. Subsequently, the American Motor Vehicle Engineer Association and the International Standardization Organization made some modifications on the basis of DIN 75201 and issued relevant standards ISO 6452 and SAE J1756. Based on the above -mentioned standards in the world's major automobile manufacturing companies, they have promulgated the corporate standards of fogging, and have put forward relevant requirements for the fog characteristics of automobile interior parts.
At present, the international and domestic auto interior material atomization test standards involve three test methods: the gloss method, weight method, and misty method, as shown in the table below:
The luster method, weight method
sae j1756 sae j1756The glossy method, weight method
The luster method, weight method Weight method
Misty method, weight method
The two test methods of the glossy method and the misty degree method are relatively close. They are the optical properties of the glass board. These two test methods are used. The impact of the sight; the weight of the weight method is to focus on the test sampleIn the content of the hair material, the experimental uses this method is often more concerned about the impact of harmful ingredients in volatile objects on human health.
Materials that exceed the standard indicator of the fog will not be used for car interior.Shanghai QINSUN can perform atomization tests such as PV 3015 Volkswagen atomization experiments such as PV 3015 Volkswagen atomization experiment and Nissan NES M0161.
