Environmental test |
High temperature: put the product in（60±2）℃ for 168h, then back to normal temperature for 2h. After that, water level change of each gear is within ±15mm |
|
|
Low temperature: put the product in (-20℃±2℃)for 168h, then back to normal temperature for 2h. After that, water level change of each gear is within ±10mm |
||
|
Humidity resistance: Put the product in (40℃±2℃, RH90%～95%)for 168h, then dry all water from the product, back to normal temperature for 2h. After that, water level change of each gear is within ±15mm |
