3.1
Under test conditions, the air fed from benzene vapor containing benzene vapor flows through the activated carbon layer time.
3.2
Under the test conditions specified, containing ethyl chloride vapor fed from the air flowing through time ethyl chloride vapor activated carbon layer.
Principle 4
4.1 benzene vapor guard time measurement principle
Under test conditions, it will contain a certain concentration of benzene vapor continuous flow of air through the sample layer, until the benzene vapor through, the finger
Until the solution becomes pale yellow shows, this time as an activated carbon benzene vapor guard time.
