Reference materials or standards are often referred to as actual chemical or physical materials called metrological standards.

The highest level of references is awarded to metrological standards that an authorized body must issue. Certified Reference Materials are considered to provide the highest level of accuracy, uncertainty and traceability to an SI unit of measurement. Reference Materials are a rung down from Certified Reference Materials though still must be
