14.1.4 CSA Z314:23
- Marking techniques used to identify instruments should be done according to the device MIFUs. Any method used to identify instrumentation shall not interfere with the integrity of the device or reprocessing method. Using marking tape or rings carries the possibility of retaining soil or residues that can harm the device or potentially increase resistance of covered micro-organisms, and it shall be inspected after each use for peeling, chipping, and soiling.
- Engraving shall not be used as it can weaken the surface of the device and allow for premature corrosion or product damage by removing the passivation (protective) layer of stainless steel.
Note: Many methods have been used to mark medical devices to facilitate traceability of instrument sets and to ensure that sets are kept together during reprocessing. Identification techniques include using tape, engraving, and sophisticated laser or acid etching. Of these methods, the use of laser or acid etching is preferred. Acid etching or laser marking can transfer a defined mark of a specified depth allowing for marking and preserving the finish protection; however, this technique might only be available from special providers or there might be an additional charge for reading these marks.
