Environmental chamber method for automotive VOC odor evaluation

Comprehensive environmental chamber

Comprehensive environmental chamber is a set of environment chamber, including a vehicle simulation cabin (5 m³) and two component testing chambers (A and, 2m³ ), in order to guarantee the accuracy of the test, the group environment chambers should be placed in the clean room (or vehicle standards in the cabin environment) to carry out the test.

Function of environmental chamber method for automotive VOC odor evaluation

Take parts A module as an example (complete vehicle and B module with the same function)

Function of environmental chamber

Advantage function

*Self-heating : 25℃, 60℃ and 65℃ temperature condition can be simulated;

*Sunlight simulation: It can simulate the VOC and smell of the vehicle in the sun of the parking lot;

*Pressure stability: The VOC sampling process can be automatically filled to ensure the stability and accuracy of the samples.

*Self-purification: Before testing, it can be cleaned (similar to the bag process) to ensure that the background is met.

*Automatic air stirring: Can automatic mixing cabin air before sampling, to ensure a uniform VOC concentration method (similar to the bag of film bag);

*Bulkhead with inert materials processing.

Conclusion: This environment holds the advantages of bag method and 1 m³ method, and has the function of combinatorial simulation verification, which improves the efficiency of the test and reduces the cost of the comprehensive test.

Simulation verification

By using A, B module and vehicle simulation cabin, we compare the similarity between the odor in the car and the cabin in the environment (Place the vehicle interior trim parts in the overall installation location of the vehicle or hang it in the integrated odor evaluation module)

R&D process

*To establish the comprehensive class method test and the standard of limit;

*The application of the integrated environment tank method was carried out in the early forward simulation design;

*The component verification gradually adopts the cabin method to replace the bag method and fills the evaluation blank of the parts of the assembly parts.

Mass production quality control process

*The VOC and odor production conformance control of the parts are gradually replaced by the method of the tank method and the method of smell evaluation;

*The bottle odor evaluation method will be used mainly for material level control;

*The odor source of the whole car is used to replace the traditional odor check method by means of integrated tank method.

Advantages of Simplewell Environmental chamber

The method reduces the adsorption capacity of the contact surface, greatly reduces the adsorption of a test object on the inner wall of the chamber and on the surface in contact with the test object of each component, so that the tested value of the samples taken from a sampling tube is closer to the actual value of the test object in the chamber, effectively improving the testing precision of the releasing chamber. EUROPEAN, USA, JAPAN PATENT OF (METHOD FOR TREATING SURFACE OF RELEASING CHAMBER IN CONTACT WITH TEST OBJECT).

The coated stainless steel wall improves the adsorption capacity of test chamber of high-boiling-point materials and polar compounds. The chamber emission gas recovery rate more than 80% of tetradecane and 4-phenyl-1-cyclohexene. It increased testing accuracy.
