A washer-disinfector is built, tested and approved in accordance with the DIN EN ISO 15883 standard. This standard lists all requirements and parameters applicable to machine reprocessing, including the A0 value. It describes the temperature acting on the surface of the instruments over time and thus forms a benchmark for the bactericidal, virucidal and fungicidal effect of instrument reprocessing. It is essential that sufficient moist heat is used in the disinfection process within the appropriate time frame to successfully inactivate viruses and kill microorganisms. For example, an A0 value of 3000 applies to area of action B, in which even thermoresistant viruses such as hepatitis B are inactivated. For this detection, a washer-disinfector must continuously document the A0 value as well as the temperature curves.
