#quality control
- Areometry — A branch of metrology and applied physics dealing with the study of techniques, methods, and mathematical principles for measuring the density or specific gravity of liquids using hydrometers. In a structural-engineering sense, areometria is based on Archimedes' principle regarding the equilibrium of floating bodies, serving as an essential quality control factor in chemical, petroleum, food, and winemaking industries.
- Self-verification — The act of self-verifying and its result; an internal, automated, or conscious process through which an entity (IT system, machine, person) examines its own behavior, data, or performance for validation.
- Bacteriometry — A method or body of laboratory techniques utilized for counting, measuring dimensions, or determining the density of bacterial colonies within a given volume of a liquid, solid, or gaseous sample. Biochemically and industrially, bacteriometry includes direct methods (microscopic or culture plate counting) and indirect methods (nephelometry, turbidimetry, or flow cytometry) necessary for quality control.
