如果工艺要求温度范围(设定温度为121℃,121℃-123℃),超过了123℃肯定是不行的。不过ISO 17665.2-2009只要求121-124℃,原文如下:
A.4.1.2 Acceptance criteria for the test are as follows.
a) The sterilization temperature band should have a lower limit defined by the sterilization temperature and an upper limit of +3 °C.
b) The equilibration time should not exceed 15 s for sterilizer chambers up to 800 l usable space and 30 s for larger sterilizer chambers.
c) During the plateau period the temperature measured above the test pack should not exceed the temperature measured at the reference measurement point of the sterilizer chamber by more than 5 °C for the first 60 s and 2 °C for the remaining period.
d) Throughout the holding time the temperature measured at the reference measurement point of the sterilizer chamber, any temperature measured at the same instant within the test pack and the respective saturated steam temperature calculated from the chamber pressure should be within the sterilization temperature band and not differ from each other by more than 2 °C (see 6.1.2).
e) The holding time should be not less than 15 min, 10 min and 3 min for sterilization temperatures of 121 °C, 126 °C and 134 °C respectively. |
