The environmental chamber can realistically simulate environmental parameters such as temperature, humidity, ventilation frequency, and air flow rate on the surface of the pattern. Through the analysis and verification of the test data results, the amount of volatile toxic and harmful (VOC) substances contained in the pattern material can be measured and calculated. The impact of its release characteristics on the environment can in turn:
Determine the impact of environmental variables on the VOC release amount and release characteristics of test materials
Classify materials based on their VOC release characteristics
Development of pattern materials and verification of indoor air VOC release pollution characteristics
The time duration attenuation of VOC emissions from model materials in the natural environment
The assessment of indoor air quality will be predicted based on the detection data analysis.
