Introduction
Improving the Confidence of the Laboratories Through ILCs!
This topic explains the purpose, process, and value of Interlaboratory Comparisons (ILCs) in demonstrating calibration competence and maintaining accreditation.You will explore different ILC types, evaluation methods (e.g. z-score, En-score), and real-world examples, including regional WMO-supported exercises. Emphasis is placed on how ILCs validate measurement consistency, identify weaknesses, and foster mutual confidence in global calibration networks.
