The System is comprehensive Environment Simulation Chamber, it is combined with one Simulation Chamber for Whole Automotive (5m³）,and two sets of different Test Chambers for Automotive Interior and Components (2 m³ of A and B each). In order to get accurate test data, we advise the system should be displayed in cleanliness room or standard environment chamber for whole vehicle.
Application about VOC Testing and Analysis System For Automotive
GB / T27630-2011 “Passenger Car Air Quality Evaluation Guide”, jointly issued by the Ministry of Environmental Protection and AQSIQ. The air quality inside the car has become a hot spot in the industry. How to control the air quality inside the car has become a key public relations issue for various OEMs. At present, the air quality control method in the car manufacturer is semi-reverse, that is, And tooling for VOC certification. If the vehicle VOC performance does not meet the national standard requirements, and then according to the host factory standard unqualified trim non-metallic parts for rectification, rectification and then load the vehicle VOC performance verification. So repeatedly, until the performance requirements so far. The method can only be carried out in the mid / late air quality control of the car, parts mold / material / technology has been identified, and then improve the more difficult / high cost / low efficiency. In response to the above issues, Ascend is also devoted to designing a car odor / VOC inspection system and applying the forward design method to overcome these shortcomings.
Ascent Automotive’s odor / VOC inspection system developed by Microelectronics is made of stainless steel plate, the surface is reduced by adsorption coating, the internal adsorption performance of the cabin is improved, the sunlight irradiation function module which simulates sunlight heating and temperature control and irradiance control by infrared ray is provided, All parameters simulate the vehicle status, reproduce the relevant parameters of auto parts release of harmful substances. Assess the contribution of each component to the car’s voc / scent under different conditions. Suitable for formaldehyde, particulate / voc / ozone / odor / nitrogen oxides / sulfur oxides and ammonia and other fields investigation test
The same can be used for bag method of formaldehyde, VOC test (using a heater inside the test chamber heating, or sample bag hot box environment heating)
The system can also be used for other industries smell / voc forward design, such as other vehicles / interior decoration furniture, air environment and other industries.
Second, Application Environment:
Performance is the ambient temperature +5 ~ +32 ℃, the voltage change allowed value is within ± 10% of the grid voltage. The allowable value of variation of the number of cycles is within ± 1% of the number of fixed cycles. The TVOC concentration of the setting place (air supply) is 500 ug / m3 or less, and there must be no significant change.
Third, the system consists of:
A. Environment Room Provide a constant temperature and clean environment of the test chamber, indirectly control the temperature / humidity in the test chamber to ensure the stability of the test Test jacket: the control of environmental temperature, humidity, cleanliness of the insulation chamber Buffer room: personnel / equipment / maintenance channel (optional) Temperature and humidity control system: jacket temperature control, indirect control of the temperature and humidity in the test chamber Exhaust system: temperature control jacket exhaust and test chamber exhaust illumination In and out: personnel, equipment, maintenance access
B. Test chamber (1 set of 5.25M3) for the whole part test C. Test Chamber (2 sets of 2M3) for parts testing D. Test with clean air system For test chamber formaldehyde, voc, odor test ventilation (or customer configuration clean gas source)
Fourth, test description: Design clean cabin (5.25m3 simulation of different specifications of the vehicle), as a test product test cabin Design clean room (2m3) as a screening compartment for single or unit component products.
Test chamber placed test article before the test, open the test chamber internal clean filtration system, cleaning test chamber
Close test chamber Internal cleaning system, test chamber run, test chamber odor / voc test.
The screening cabin odor / voc is tested after placing the parts or unit materials to be screened in the screening tank. One by one to examine the impact of vehicle odor and voc components or units, determine the main and secondary factors that affect vehicle performance, improve the design process.
Forward Design and the Problems in Toxicant VOC Troubleshooting
Question: how can we check the whole automotive and components simulation test?
Sample-bag Method: can’t test the automotive assembly, can offer group test and verification about VOC and Odor to Whole Automotive.
1m³ Chamber: can’t offer comprehensive test to whole automotive VOC and Odor.
