                                                   Cycle A

C.1 Salt fog test solution

Prepare the spray solution as described in Clause 5 by dissolving sodium chloride in water to give a concentration of (50±10)g/l .The PH of the solution shall be in the range 6 to 7.

 

C.2 Cycle

Set up the cabinet to perform the following cycle.

Go back to step 1

This makes a total cycle time of 8h from step1 to step3

 

Transtition time（ie time allowed to reach the temperature and relative humidity specified for a condition after changing to that condition）：

From salt spray to dry：within 30min

From dry to wet：within 150 min

From wet to salt spray：within 30min

The effect of the salt spray will，in principle，be instaneous。

For details of drying-air flow，see 6.4

NOTE  Set points and operational fluctuations can be listed either independently of each other or in the format：set point±operational fluctuations.The set point is the target condition for the sensor when used at the operational control point as programmed by the user.Operational fluctuations are deviations from the indicated set point at the control point indicated by the readout of the calibrated control sensor during equilibrium operation and do not include measurement uncertainty.At the operational control point , the user programmes that exat number . The operational fluctuations specified for that set point do not imply that the user is allowed to programme a set point higher or lower than the exact set point specified.

 

C3 Salt fog depsiton rate

The salt fog deposition rate shall be 1ml/h to 2ml/h,when the salt fog iscollected over a 24h period (see Clause 10)

C 4 Duration

Unless otherwise agreed，repeat the test cycle for 30 cycles(240h),60cycles(240h),90cycles(720h) or 180cycles(1440h)
