This document does not cover processing of single-use medical devices provided as sterile before use and textile devices.
NOTE 2        Manual cleaning steps before automated cleaning do not include steps that are considered point of use treatment that can be specified.
NOTE 3 Microbiocidal processes (sanitization, disinfection, sterilization) are not in the scope of the medical device cleaning classification categories.
