The F-value for steam sterilization (F0) is a measurement tool used to demonstrate accumulated lethality and must be used in both validation and routine monitoring of cycles to demonstrate that acceptance criteria for F0 has been met.
The F0 algorithm was first introduced in 1968 in the international practice of food industry, and proposed by FDA in 1976 for the pharmaceutical sterilization of Large Volume Parenterals: it is now officially included in most Pharmacopoeias.
F0 is a means for quantifying steam sterilization effectiveness by determining the equivalent sterilization time in minutes relative to a base temperature of 121 °C and a z-value of 10 °C ...
23 sty 2023 · To calculate the F0 value, average the temperature of each probe during the sterile hold and then average the different temperatures to get one single temperature. Use the formula shown in below to estimate the F0 value: Where, F0 Value = Equivalent Exposure Time. Δt = the time interval between two temperature readings.
This document discusses the application of the F0 concept to steam sterilization of aqueous preparations. It defines several key terms used in sterilization processes, including F0 value, D-value, Z-value, and inactivation factor.
22 mar 2022 · This article has procedure for autoclave validation including steam penetration, heat distribution and penetration, bio-challenge study, estimation of F0 value and acceptance criteria of steam sterilizer validation in pharmaceutical industry.
The F-value (sterilization intensity) is often used when sterilizing ready-made foods and canned foods. The F-value is a measure of the time required to kill microorganisms at a given temperature. Heating at 121°C for 1 minute is defined as F-value =1.
