Three brief videos break down recently-revised standards terminology to help you understand the background behind the change, and the importance of correct usage.
Ensuring that everyone is speaking the same language is critical for communication between scientists in the laboratory. While precision and accuracy are generally understood, the relation of the term trueness can be a mystery. This video describes all three terms and their relationship to one another.
The term “trueness” has been used in other industries for some time. The ISO IWA 15 (ISO International Workshop Agreement, finalized in 2015) aligns liquid handling in life sciences with the rest of the world by providing a definition for trueness along with 49 other terms.
This video explains how the ISO IWA 15 applies current definitions from the international vocabulary of metrology (VIM) and adapts them for the specific case of automated liquid handling systems.
