Our standard
Known Matter gives people the information needed to understand what they are choosing, what a result means and what to do next.
Our products start with a practical question and focus on the information needed to make a useful decision.
Technical detail should support people, not hide the answer. We present results, specifications and instructions in plain language.
We state what a product or service does, what it does not do, and where a different test, tool or professional is more appropriate.
