VOC Pretreatment Room
Pretreatment room can provide standard temp.,humidity and voc clean
environment.After temp. humidity,pressure and voc of testing
materials are released in balance,pollutant release rate and
release properties of material and products will be tested.
Place materials and products or their samples in the pretreatment
room, and adjust indoor temperature,relative humidity,wind
speed,pressure,indoor voc cleanliness conditions and other
environmental conditions,so that temperature and humidity of test
samples can reach consensus,and internal and external pressure of
them in balance.Meanwhile,crossed contamination of test samples
should be avoided (crossed contamination of TVOC release and
crossed contamination of single unit VOC)
Range of temp. and humidity:
45~50%R.H.±5%,wind speed under 0.3m/s
VOCS is required to be air intake volatility.
Organic concentration should nor exceed the following indexes
1. No pollutant source in the surrounding environment.
2. Power:AC380V 20KW(this power is set for one set of machine
unit,and general power shall accumulate if the inner volume is
relatively big and 2 or 3 machine units are adopted.)
