DataTrace in Autoclaves
In the course of having your equipment calibrated, you may have heard the terms “As Found,” “As Received,” “Pre- and Post- Verification,” or “Before and After Data.” These expressions are used interchangeably, but what do they mean?
What is As-Found Data?
Here at Mesa we use the term “As Received Performance Data,” and we define it like this: As Received data records the performance of a logger when we receive it here at our lab. This is before any repairs, adjustments, upgrades, or calibrations take place. In short, we want to know how close to perfect the calibration is of your logger after you’ve used it. This data is often used to validate processes that have already taken place. As Received data helps you answer the question: “My loggers have been in some pretty rough conditions. Are they still in an acceptable range of calibration?”
How Do I Know If I Need It?
While this is by no means a universal rule, we have noticed that As Received Performance Data is required regularly in the medical and pharmaceutical industries, yet rarely in the food industry. It is almost universally required when humidity loggers have been used in EtO sterilization. This is a good guideline, but the need for this data will ultimately be determined by your specific internal requirements, or the requirements of the governing bodies to which you may be accountable. Some customers don’t require As Received Performance Data but they occasionally request it as a means of observing the effect of their process on their loggers’ ability to stay in calibration.
