Certified Reference Materials (CRMs): Highest level of characterization and traceability (ISO 17034) with detailed documentation, suitable for regulatory QC and method validation.
Reference Materials (RMs) may not always meet the same strict certification as CRMs but are used in calibration and routine QA.
Pharmacopoeial Reference Standards (e.g., USP, EP, BP) are official primary standards used for compliance with pharmacopeial monographs.
