ISO 17034 Standard
General Requirements for the Competence of Reference Material Producers
The ISO 17034 standard is the ultimate international benchmark that specifies the general requirements for the competence and consistent operation of reference material producers (RMPs). It is the core framework that ensures the Reference Materials (RMs) and Certified Reference Materials (CRMs) used to calibrate laboratory instruments, validate testing methods, and control quality are produced to the highest scientific standards.
1. Overview of the Standard
Developed by the ISO Committee on Conformity Assessment (CASCO), ISO 17034 outlines the quality and technical requirements that producers must meet to prove they can generate reliable reference materials. Reference materials act as the "golden yardsticks" of the scientific world. ISO 17034 places heavy emphasis on proving homogeneity (ensuring the material is uniform throughout), stability (ensuring the material doesn't degrade over time), and establishing metrological traceability with clearly calculated measurement uncertainties.
2. Target Sectors Served by the Standard
ISO 17034 is vital for organizations that manufacture the calibration and testing standards relied upon by accredited testing laboratories (such as those under ISO/IEC 17025). Key sectors include:
Chemical & Analytical Metrology: Producers of chemical solutions, pH standards, and pure organic/inorganic compound standards.
Pharmaceuticals & Lifesciences: Manufacturers of reference standards for drug purity, active pharmaceutical ingredients (APIs), and biological materials.
Clinical & Healthcare: Producers of reference materials for blood serum controls, toxicological standards, and medical diagnostic kits.
Environmental Analysis: Providers of certified matrix standards, such as soil or water samples with precisely known concentrations of pollutants or heavy metals.
Metallurgy & Materials Science: Producers of certified metal alloys, polymers, and minerals used to calibrate X-ray or spectroscopic instruments.
Food & Agriculture: Manufacturers of reference materials for pesticide residues, food allergens, and nutritional components.
3. Key Clauses of the Standard
The standard mirrors the high-level architecture of other conformity assessment standards, focusing on technical integrity during material production:
Clause 1: Scope: Sets out requirements for producing both certified and non-certified reference materials.
Clause 2: Normative References: Includes key underlying documentation (such as ISO Guide 30 and ISO/IEC 17025 principles).
Clause 3: Terms and Definitions: Clarifies vital terms like "Certified Reference Material (CRM)", "certified value", and "property value".
Clause 4: General Requirements:
Impartiality: Ensuring that commercial or organizational interests do not compromise production data or values.
Confidentiality: Safeguarding client data and internal formulation secrets.
Clause 5: Structural Requirements:
Defines the legal status of the producer, its organizational chart, and its management accountability.
Clause 6: Resource Requirements:
Personnel: Competence, training, and authorization of staff handling delicate formulations and measurements.
Subcontracting: Strict control and monitoring when an external laboratory is used to test or package the material.
Equipment & Facilities: Ensuring production areas prevent contamination and that measuring tools are highly accurate.
Clause 7: Technical and Production Requirements:
Production Planning: Comprehensive mapping of the lifecycle of the reference material.
Material Handling & Processing: Sourcing, synthesizing, and packing materials without degrading them.
Homogeneity Assessment: Scientifically testing to prove that every single vial or batch is identical.
Stability Assessment: Testing the material under various temperatures and time frames to determine its shelf-life and shipping conditions.
Characterization & Assignment of Values: Using scientifically sound methods to determine the exact value of the material's properties.
Certificates & Documentation: Issuing formal certificates that detail the property values, uncertainty margins, expiration dates, and traceability data.
Clause 8: Management System Requirements:
Outlines documentation controls, internal quality audits, management reviews, and corrective action systems tailored to continuous improvement.
