LEVOC
Auto Interiors Emission Test Chamber LEVOC
Application
The auto interiors LEVOCemission test chamber can provide a standard test environment (such as specified temperature,relative humidity,air exchange rate and airflow rate, LEVOC) or simulate a real indoor environment to test rate and release rate and release properties of pollutants from various interior materials and products.
From the test results,users will Determine the impact of environmental variables on material and products release rates and release characteristics.
Product Details
- Classify the materials and products grade according to their release characteristics.
- Develop,verify and predict models of indoor air pollution.
- Evaluate indoor air quality (IAQ) according to indoor pollutant data or predicted model.
Test principle
- Air is compressed by air compressor,and the solid particles,formaldehyde,volatile organic compounds in the air are removed.Then the purified air is released into the test chamber.
- The climate box adopts a jacket.The temperature of the test chamber is indirectly adjusted through controlling the temperature of jacket.
- Dew point method is applied to adjust humidity of the climate chamber and humidity inside the test chamber.The method is simple and effective.

Model LEVOC-1000A LEVOC-1000B LEVOC-2000 Environment temperature 5℃~35℃ Environment humidity ≤90%R.H Environmental cleanliness requirements There is no pollution source in the surrounding environment.TVOC≤500ug/m³ Climate chamber volume (mm) D1580×W800×H800 D900×W1000×H1100 D910×W2000×H1100 Temperature adjustable range 20℃~100℃ High temperature cleaning 250℃ or above Humidity adjustable range 40~70%R.H.(20~30)℃,when it is in line with ADA276,humidity is 5% 65℃ Pressure 10±5pa Temperature fluctuation ±0.3℃ Temperature deviation ±0.5℃ Humidity fluctuation ±2.5%R.H Humidity deviation ±3% Air exchange rate 0.2~5time/h±5%(Optional exchange rate specifications Power supply AC 380V/50Hz/3-phase power supply 5-wire system Start power 25kw 25kw 30kw Running power 12kw 12kw 13kw LEVOC background concentration Single LEVOC concentration less than 2ug/m³;TVOC concentration less than 20ug/m³ Recovery rate The recovery rate of toluene,dodecane or tetradecane is more than 80% Clean air system Standard configuration Technical advantage
The coated stainless steel inner wall improves the adsorption capacity of LEVOC substances with high boiling point and polar compounds.The recovery of tetradecane,4 phenyl cyclohexene is more than 80%.
The patent is about how to deal with the connection surface LEVOC emission chamber and the testing object.The technology helps to reduce the surface adhesive force,largely reducing LEVOC’s adhesiveness on chamber’s interior adhesiveness on chamber ,and the testing precision of emission chamber is largely improved.
