德國DIN EN ISO11997-1循環腐蝕測試標準及復合鹽霧測試方法

Cycle A

C.1 Salt fog test solution鹽霧試驗溶液

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條所述的方法制備噴霧溶液，將氯化鈉溶解在水中，使溶液的濃度為（50±10）g/L，溶液的pH值在6～7范圍內。

C.2 Cycle

Set up the cabinet to perform the following cycle設置鹽霧箱執行以下循環

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
	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 從鹽霧到干燥：30min內 From dry to wet：within 150 min 從干到濕：150分鐘內 From wet to salt spray：within 30min 從濕到鹽霧：30分鐘內 The effect of the salt spray will，in principle，be instaneous。 For details of drying-air flow，see 6.4 鹽霧的效果在原則上是瞬時的。有關干燥空氣流量的詳細信息，請參見6.4

C.3 Salt fog depsiton rate鹽霧沉降率

The salt fog deposition rate shall be 1ml/h to 2ml/h,when the salt fog iscollected over a 24h period (see Clause 10)
當鹽霧在24小時內被收集時，鹽霧的沉積速率應該是1ml/h到2ml/h（見第10條）

C 4 Duration持續時間

Unless otherwise agreed，repeat the test cycle for 30 cycles(240h),60cycles(240h),90cycles(720h) or 180cycles(1440h)
除非另有約定，重復測試周期30周期（240h）、60周期（240h）、90周期（720h）或180周期（1440h）

Cycle B

C.1 Salt fog test solution鹽霧試驗溶液

C.2 Cycle

Set up the cabinet to perform the following cycle. 設置鹽霧箱執行以下循環。

Step	Time h	Temp ℃	Condition	notes
1	24	35±2	Salt fog
2	8	40±2	99%RH	Water condensing on test panels
3	16	23±2	（50±20）%RH
4	8	40±2	99%RH	Water condensing on test panels
5	16	23±2	（50±20）%RH
6	8	40±2	99%RH	Water condensing on test panels
7	16	23±2	（50±20）%RH
8	8	40±2	99%RH	Water condensing on test panels
9	16	23±2	（50±20）%RH
10	48	23±2	（50±20）%RH
11	Go back to step 1			This makes the total cycle time 7 days from step1 to step10.
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.

C 3 Salt fog depsiton rate鹽霧沉降率

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持續時間

Unless otherwise agreed，repeat the test cycle for 840 h
除非另有約定，重復測試周期為840小時。

Cycle C

C.1 Salt fog test solution鹽霧試驗溶液

Prepare the spray solution as described in Clause 5 by dissolving sodium chloride in water to give a concentration of (0.31±0.01)g/l and (4.1±0.01)g/l respectively .The PH of the solution shall be in the range 6 to 7.
按照第5條所述的方法制備噴霧溶液，在水中溶解氯化鈉，濃度分別為（0.31±0.01）g/L和（4.1±0.01）g/L，溶液的pH值在6～7范圍內。

2	210	40±2	Dry	Drying-air purge(see 6.4)
3	1470	40±2	（75±15）%RH	One method of achieving this conditon is to alternate the dry and humid cycles for suitable(short)time periods to keep the RH between the limits specified
4	102	30±2	Dry	Drying-air purge(see 6.4)
5	210	30±2	Salt fog
6	378	30±2	90% to 99%RH	Water condensing on test panel
