reference standards
Authoritative measurement guides
Reference standards are specimens or substances with precisely known properties, used to calibrate instruments or validate measurements.
A laboratory might use a reference standard to ensure its equipment reads accurately: The pH meter was calibrated against certified reference standards.
In manufacturing, reference standards establish benchmarks for quality control—a color swatch, a weight, a chemical sample of guaranteed purity.
