New material vehicle reliability test, NVH test, HVAC test, EMC test, chemical analysis test, and vehicle road performance test

The vehicle testing project mainly includes six parts, which are vehicle reliability testing, NVH testing, HVAC testing, EMC testing, chemical analysis testing, and vehicle road performance testing. Next, let's introduce them one by one.

1.1 Vehicle reliability test

The vehicle reliability test mainly includes environmental adaptability test, sealing performance test, road durability test, indoor simulated collision and durability test, etc. The main experimental items are as follows:

1.2 NVH Test

NVH refers to Noise, Vibration, and Harshness, as well as issues related to the strength and lifespan of automotive components caused by vibration. What passengers perceive (auditory, tactile, and visual) is a comfortable driving or riding environment. The main experimental items are as follows:

1.3 HVAC Test

HVAC is Heating, The abbreviation for Ventilation and Air Conditioning is heating, ventilation, and air conditioning. HVAC testing, also known as heating, ventilation, and air conditioning testing, mainly includes emission and economy testing, vehicle air conditioning system testing, cooling system testing, instrument verification testing, temperature field testing, weather resistance testing, and other testing items. The main projects are as follows:

1.4 EMC Test

EMC testing, also known as electromagnetic compatibility (EMC), refers to the comprehensive evaluation of the interference level (EMI) and anti-interference ability (EMS) of electronic products in electromagnetic fields. It is one of the most important indicators of product quality, and the measurement of electromagnetic compatibility is composed of testing sites and testing instruments. The main test items for automotive EMC testing are as follows:

1.5 Chemical analysis test

The chemical analysis test mainly includes ELV vehicle disassembly testing, vehicle VOC testing, and odor evaluation. ELV testing refers to the detection of prohibited substances in automobiles, while VOC testing refers to the detection of volatile organic compounds in the entire vehicle.

1.6 Vehicle Road Performance Test

The vehicle road performance test mainly includes parameter measurement, inspection test, break in test, coasting test, power test, fuel economy test, braking test, smoothness test, handling stability test, and other contents. The main experimental items are as follows:
