Overview
IEC 63085:2021 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the technical performance requirements and testing methods for Raman systems used in the spectral identification of liquids. These systems operate based on the principle of inelastic (Raman) light scattering by molecules, allowing for non-destructive identification of liquids within transparent and semitransparent containers. The standard applies to both stationary and hand-held Raman analyzers, focusing on their functionality and operational reliability rather than design specifics such as geometry or mass.
This standard outlines criteria for substance identification testing, system verification, approval, and operational protocols. It is particularly relevant for applications in radiation protection instrumentation, security screening, medical solution inspection, and chemical analysis, ensuring that Raman systems meet rigorous benchmarks for accuracy, reproducibility, safety, and environmental resilience.
