This part describes the strength calculation of the autoclave for steam sterilization of medical devices waste according to the SIST EN 13445 standard. The working pressure of the autoclave is between -1 bar negative pressure up to 4 bar positive pressure, at a maximum working temperature of 110 㓦C. First, the theoretical foundations and a comparison between a stationary and a mobile autoclave are presented. This is followed by a detailed and structured recalculation of all the main components of the pressure vessel and then a numerical analysis of the comparison of the product made in accordance with ”good engineering practice”and the standardized one. A risk assessment was made for the entire autoclave assembly in accordance with the SIST EN ISO 12100 standard.
