What test does a qualified car need to go through before leaving the factory?
Huajun Tire Factory
Shanxi automobile inner tube manufacturersIt is said that the performance and processing technology of non-metallic materials are changing with each passing day, which makes it be applied to automobiles at an unprecedented speed. The average amount of non-metallic materials used in each car has increased from 68.4kg in 1981 to 150-180kg at present.
At the same time, the market has put forward higher requirements for the detection of the corresponding properties of such materials, such as the influence of the condensation of volatile substances of automobile interior materials on the windshield on the driving safety of drivers, the air permeability of plastic fuel tanks, inner tubes, and safety The barrier property of airbags and so on. In view of these problems, the corresponding detection methods, detection standards and detection instruments have been introduced and continuously improved.
Fogging detection of interior trim parts:
Shanxi automobile inner tube manufacturers said that automobile interior decoration materials, such as engineering plastics, textiles, leather, non-woven fabrics, etc., as well as various adhesives used to install these materials, under the action of high temperature, their easily volatile components will evaporate and form condensation on car windows or windshields, causing poor sight of drivers and seriously affecting driving safety. At present, foreign countries have this aspect of testing, follow the relevant test standards for IN75201, ISO6452, SAEJ1756 and so on. Some domestic automobile and interior parts manufacturers have also paid enough attention to relevant testing in order to improve product quality or develop overseas markets.
Shanxi automobile inner tube manufacturers said that there are two test methods for the atomization detection of interior trim parts: gloss test method and weight test method. The former is to measure the atomization characteristics of the tested sample by the change of the gloss of the glass plate before and after atomization; the latter is to obtain the quality of the atomized condensate by the change of the quality of the aluminum foil before and after atomization. In addition, the "fogging value" or "atomization-condensate quality" obtained by the test can also quantitatively obtain the volatilization of toxic and harmful substances in the sample; through the test of the atomization value of the front xenon lamp, it can also Test the degree to which the atomization phenomenon of the headlights will affect the illuminance.
