Operating Condition

Remark

1. Environment Temp. : 5℃-35℃; 

2.Relative Humidity: ≤85%RH; 

3.Atmospheric Pressure：80kPa~106kPa

4. Away from strong vibration source

5.Powersource:

1. 380V AC,50Hz three phase, earthing resistance≤4Ω; Power capacity：7.0kw
2. Specimen power control connector adopt relay contact control method, （Contact closing when machine running normally, when machine under stop or fault ,contact switch power turn off ,run into protection state )
3. Frequency: 50Hz
4. Environment air quality requirement: without high density powder, easy firing, easy explosive air or powder, away from strong electromagnetic source
5. Avoid test or storage of easy firing, easy explosive, volatilization and corrosive specimens.
6. Standard specimen place requirement：
6.1 Specimen weight less than 80KG/m³
6.2 Whole specimen dimensionless than 2/5 of the chamber inner volume, each layer less the 2/5 area. Otherwise will seriously effect the chamber performance or the normal
operation.
