Test products: seat cover, seat foam, instrument panel skin, door panel skin, ceiling, carpet, soundproof cotton tape. Test items: Folding fastness, abrasion resistance, Martindale abrasion, softness, breathability, chemical resistance, scratch resistance, compression fatigue, low temperature flexibility, high temperature cooking.
Automotive polymer material testing
Automobile high-scoring materials test content includes the mechanical performance test, thermal performance test, aging performance test, component analysis, abrasion performance test, combustion performance test of plastic and rubber raw materials and their finished products.
Automotive ELV test
This test mainly tests lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers on vehicles, parts, and raw materials according to EU ELV Directive 2000/53 / EC or national standard GB / T 30512; Other regulations, such as REACH, test related harmful substances, such as asbestos and polycyclic aromatic hydrocarbons, to help build a green automotive industry chain.
Automotive VOC test
Automotive VOC testing mainly conducts comprehensive VOC tests on complete vehicles, assemblies, and materials to enable products to meet international, national, and corporate standards, thereby creating a green and safe riding environment. The main test items include vehicle, cabin method, bag method, odor, atomization, formaldehyde, total carbon, VDA.278, etc. Test standards such as international standards ISO 12219 series, VDA series, DIN series.
Automotive cyclic corrosion test
The cyclic corrosion test of automobiles effectively simulates the changes in atmospheric temperature and humidity, and adds severe weather factors such as simulated rainfall and high humidity and heat, so that daily-used coatings and coated products can withstand more severe corrosion erosion in a shorter period of time. , So as to better show the experimental results and performance results that fit the user's formal use conditions
Electromagnetic compatibility testing of automotive electronics
Through testing the electromagnetic compatibility parameters of more than 50 kinds of automotive electronic components such as automotive meters, air-conditioning controllers, car audio, navigation infotainment systems, body control modules, various types of lights, motors, etc., to ensure the Minimal interference.
Automotive coating plating material testing
Testing of automotive coatings and electroplating materials, including various surface properties and reliability tests of trim strips, painted parts and electroplated parts, for door panels, interior and exterior trim strips, interior and exterior trim frames, bumpers, deflectors, coating thickness-ISO 2808, Film Adhesion-ISO 2409, Linear Wear-ISO 105 X12, Scratch Resistance-ISO 1518-1, Crushed Stone Impact, Light-SAE J2412, Pencil Hardness-ISO 15184.
