Protective Earthing
Impedance
The impedance between protective earthing point of the power input
faucet and protective earthing can be touched all metallic parts,
doesn’t over than 0.1Ω.
Successional Current
Leakage under Work
Temperature
a) Earth leakage current on the normal condition: ≤0.5mA, the single
blooey state: ≤1 mA
b) Crust leakage current on the normal condition: ≤0.1 mA, the single
blooey state: ≤0.5mA
Dielectric strength
with Working
Temperature
a) A-al: It should bear the sine wave test alternative voltage, 50Hz,
1500v, which between the web power input port and protective
earthing can be touched all metallic parts. It lasts 1min, and hasn’t the
phenomenon of breakage and flashover.
b) A-a2:It should bear the sine wave test alternative voltage, 50Hz,
1500v, which between the web power input port and the enclosure of
which isn’t be pretended earthing. It lasts 1min, and hasn’t the
phenomenon of breakage and flashover.
For all loads except hollow load A, the presence of saturated steam in
the usable space and the load is deemed to have been achieved
when, throughout the holding time, all temperatures measured in the
usable space and the load.
Attention: the theory of steam temperature is accounted by measuring
pressure, which can be considered the test temperature.
are not lower than the sterilization temperature.
are not more than 4 K above the sterilization temperature.
do not differ from each other by more than 2 K.
The usable place temperature during the no-load can not over than
the scope of highest temperature.
For hollow load A and B, in order to confirm the presence or absence
of saturated steam, discriminate whether the indication system
change in accordance with the system manufacturer predetermined
color.
Dryness, Solid and
Wrapped Load
For wrapped load, any remaining moisture should not lead to wet
packages and shall not result in detrimental effects on the sterilizer
load. Any remaining water droplets on the inner side of pouch should
evaporate within 5 min.
For solid load the moisture content should not exceed 0.2%.
