DEFINITION

Classification: 264/40.1

(under the class definition) Processes include the step of sampling, audibly or chemically testing or inspecting, or otherwise physically or mechanically determining some variable condition in a shaped article, molding material, the mold or shaping surface.

(1) Note. Included herein are processes for determining imperfections or for determining completeness of a reaction or manipulation as well as determinations of undesired variations which activate correction mechanisms. Recitations of optimum or desired temperatures of pressures or proportions of ingredients are considered nominal only and are classified with the disclosed process on some other basis.
