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(nèi) From dry to wet:within 150 min 從干到濕:150分鐘內(nèi) From wet to salt spray:within 30min 從濕到鹽霧:30分鐘內(nèi) 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(shí)的。 有關(guān)干燥空氣流量的詳細(xì)信息,請(qǐng)參見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. |
Step | Time min | Temp ℃ | Condition | notes |
1 | 210 | 30±2 | Salt fog | |
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 |
