详细信息
品牌：德国Liebisch 型号：SKBWF1000A-TR 加工定制：否 工作室尺寸：1535x860x660 mm 温度范围：50 ℃ 温度波动度：0.5 ℃ 温度均匀度：1 % 腐蚀物沉降量：1-2 mL/80C㎡﹒h
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.

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)
Cycle B
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.
