Assigning of Load numbers:

For autoclave loads write as follows

  • For HPHV process AH250001,

where

 “AH” indicates the HPHV process,

“25” indicates the year and

“0001” Indicates the load number 1 and the sequence follows for the next cycle.

  • For “STANDARD PROCESS” process AS250001,

Where

“AS” indicates the standard process,

“25” indicates the year and “0001” Indicates the load number 1 and the sequence follows for the next cycle.

  • For “Bowie DICK TEST” process AB250001,

Where

“AB” indicates the Bowie Dick test,

“25” indicates the year and

“0001” Indicates the load number 1, and the sequence

follows for the next cycle. This test can be performed once in a month with a grace period of 3 days.

  •  For “VACCUM LEAK TEST” process AL250001,

Where

“AL” indicates the Vacuum leak test,

“25” indicates the year and

“0001” Indicates the load number 1 and the sequence follows for the next cycle.

Daily once can be done before the sterilization cycles.
