ISO 33401:2024 - Reference Material Certificates & Documentation

Reference materials — Contents of certificates, labels and accompanying documentation

ISO 33401:2024 offers a comprehensive framework for documentation requirements accompanying reference materials (RMs), including certificates and labels. Meticulously detailing mandatory, recommended, and optional information categories, this standard enables reference material producers (RMPs) and users to ensure fitness for purpose, regulatory compliance, and effective traceability in all analytical processes.

Scope and main features:

• Certificate Structure: Mandates key data points (title, unique identifier, property value and uncertainty, intended use, storage, period of validity, etc.) for product information sheets and reference material certificates
• Traceability: Requires explicit statements on metrological traceability and measurement uncertainty for certified reference materials (CRMs)
• Labels: Details minimum requirements to ensure unique identification and prevent mix-up or misuse
• User Guidance: Clarifies roles of documentation for controlling quality, assisting method validation, and facilitating auditing

Who should comply?

• Reference material and CRM producers
• Analytical and calibration laboratories
• Regulatory authorities and accreditation bodies
