What Does SAL Stand For?

SAL stands for Sterility Assurance Level

Sterility Assurance Level (SAL) refers to the probability of a sterility failure in a sterilized product. It is a critical parameter in the validation of sterilization processes, indicating the level of assurance that products are free from viable microorganisms. SAL is typically expressed as a numerical value, often set at 10^-6, which signifies that there is a one in a million chance of a sterility breach. This metric is essential for ensuring the safety and efficacy of sterile medical devices, pharmaceuticals, and other products requiring aseptic conditions.
