Grade 1 0.7≤D<1.0
Grade 2 0.3≤D<0.7
Grade 3 0≤D<0.3
5 Test method
5.1 Test conditions
The test conditions shall be as follows unless otherwise specified:
a) Ambient temperature: (23±2)℃;
b) Relative humidity: (55±5)%;
c) Supply voltage: rated voltage;
d) Supply frequency: (50±1) Hz;
e) Water temperature: (15±2)℃;
f) Inlet water pressure: (0.24±0.02)MPa.
Note: If the rated voltage of the test prototype is different from that of the national work order system, the test shall be conducted according to the nominal voltage of the power supply system.
