Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 ℃ +68 ℉.
2) A typical sample applied with a supply voltage of 24 V, a distance of 100 mm 3.937 in from the front surface of the air flow outlet and a pressure of 0.25 MPa. (Measured on a sample left in the atmosphere at a relative humidity of 65 % RH or less for 24 hours or more.)
3) A typical sample applied with a supply voltage of 24 V, a distance of 300 mm 11.811 in from the front surface of the air flow outlet and a pressure of 0.25 MPa.
4) Dried clean air is the air passing through air dryer (dew point –20 ℃ –4 ℉ approx.) and air filter (mesh size 0.01 μm 0.0004 mil approx.)
5) "DSC" is an abbreviated name of "DISCHARGE".
6) Discharge halts when lights up.
