A batch code comprises a simple sequence of numbers, such as that produced from a labelling gun, or can be combinations
of a number sequence with codes for the date and the steam steriliser number (if the practice has several steam sterilisers).
As described in AS 4815 section 8.5.2.1, the batch control identification includes the steriliser identification number or
code (if there is more than one steriliser within the facility), the date of sterilisation, and the cycle or load number.
Batch information can be recorded on packs prior to steam sterilising using non-soluble permanent marker ink, or by using
adhesive labels applied with a labelling gun, provided that the inks and adhesives used can tolerate steam sterilising.
Several segmented (piggyback) adhesive label systems are available, where one part of the label is peeled off the pack
when setting up for the procedure, and placed directly under the day’s entry on the patient’s hard copy chart.
