Testing item
Request of standards
1
Exterior
The exterior of sterilizer should be tidy and mustn’t have
disfigurements, e.g.deflection, hollowness, collision, nick, sharp edge.
2
Cover plate
The cover plate should be assured to disassemble easily in order to
repair the equipment.
3
Digit and letter
The digit and letter in screen should be legible.
4
Electroplate
Component
The electroplate should accord with YYOO76-1992 class 2, which for
the request of aspect.
5
Printer Component
The printer components should accord with YY1055-1999 the class Ⅱ
which for the request of aspect.
6
Door Safe Lock
On the normal condition, if the sterilizer door hasn’t been locked
tightly, the program can not start.
7
Chamber Pressure
The sterilizer should ensure that the door can’t be opened when
chamber pressure is greater than 0.27kPa.
8
Safety Valve
The sterilizer must install a safety valve, safety valve opening
pressure 0.27kPa ± 0.01kPa, and automatically open when reaching
the set value.
9
Sterilizing Program
Sterilizer should have the pre-established program about 121℃ and
134℃, dressing and instruments.
10
Controlling System
The control system in sterilizer should limit the steam which in the
chamber be controlled at the highest average temperature in ±3℃ of
pre-establish station. And ensure the temperature value accords with
the pressure controlling value.
11
Timing Control
Able to timing control of the sterilization and drying, and the error
should not be greater than 10% of the preset value.
12
Button and Switch
Buttons and switches should be flexible and reliable on the sterilizer.
13
Indicator and Display
The indicators and displays of sterilizer should show the states of
every sterilizing procedure exactly. Under the normal situation,
sterilizer should indicate:
a) Chamber temperature
b) Chamber pressure
c) Sterilizer working state
d) Water level state
e) State of door
14
Quantum of Leakage
In the condition of the vacuum - 0.07Mpa, the sterilizer shouldn’t leak
0.13kPa/min.
15
Leakage Forbidden
The sterilizer can’t leak under the work pressure
