德国DIN EN ISO11997-1循环腐蚀测试标准及复合盐雾测试方法

Cycle A

C.1 Salt fog test solution盐雾试验溶液

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.
按照第5条所述的方法制备喷雾溶液，将氯化钠溶解在水中，使溶液的浓度为（50±10）g/L，溶液的pH值在6～7范围内。

C.2 Cycle

Set up the cabinet to perform the following cycle设置盐雾箱执行以下循环
Step Time h Temp ℃ Condition Notes
1 2 35±2 Salt spray  
2 4 60±2 Dry：20-30%  
3 2 50±2 Wet：95%RH or over  
4 Go back to step 1 This makes a total cycle time of 8h from step1 to step3

从盐雾到干燥：30min内
From dry to wet：within 150 min
从干到湿：150分钟内

The effect of the salt spray will，in principle，be instaneous。
For details of drying-air flow，see 6.4
盐雾的效果在原则上是瞬时的。
有关干燥空气流量的详细信息，请参见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.
