So how do we know all those sanitizing gels and wipes actually work?  And how do we know they are safe for humans to use?  The products and components are tested by materials testing services such as NSL Analytical, using ASTM (American Society for Testing and Materials) or AOAC (Association of Official Analytical Chemists)  approved methods. 

There are different tests used to ensure the effectiveness of a chemical disinfectant which can tell general effectiveness against particular microbes.  When a new threat is posed, new tests y materials testing services can tell whether the products containing disinfectants will be effective.
