Reference Material (RM):
A reference material, or RM, is a material with a known grade and/or chemical composition that is typically used for alloy or grade identification.
Certified Reference Material (CRM):
A certified reference material, or CRM, is a material that has been thoroughly analyzed and characterized using multiple validated methods to determine its chemical composition. The results of these analyses are then used to establish certified values, along with associated uncertainties. CRMs are produced and certified by accredited organizations or laboratories following internationally recognized standards, such as ISO Guide 34 (ISO 17034).
