ISO 17034 Accreditation Assessment: What Reference Material Producers Should Expect

Author : Accreditation consultancy | Published On : 23 Oct 2026

Reference material producers must demonstrate technical competence, reliable production practices, and consistent quality to gain confidence in their materials. An ISO 17034 accreditation assessment evaluates whether a producer can consistently manufacture reference materials that meet their intended purpose. Understanding the assessment process helps organizations identify gaps, organize technical evidence, and prepare for accreditation more effectively.

What Is an ISO 17034 Accreditation Assessment?

ISO 17034 specifies general requirements for the competence and consistent operation of reference material producers. It applies to producers of reference materials (RMs), including certified reference materials (CRMs).

During an assessment, the relevant accreditation body evaluates whether the producer has appropriate management systems, competent personnel, controlled production processes, and reliable technical methods. The assessment approach and additional requirements depend on the accreditation body's applicable procedures.

Key Areas Evaluated During the Assessment

1. Quality Management System and Documentation

Assessors review the documented management system and supporting records to determine whether applicable requirements are implemented effectively. Important documents may include quality manuals, procedures, work instructions, production records, internal audit reports, and management review records.

Documentation should reflect actual operations rather than simply exist for assessment purposes. Clear responsibilities, controlled records, and evidence of implementation help demonstrate compliance.

2. Technical Competence and Production Controls

Technical competence is essential for producing reliable reference materials. Assessors may examine production planning, material handling, equipment suitability, personnel qualifications, and the methods used to establish material properties.

Producers should maintain appropriate technical records showing how production activities are controlled and how decisions are supported by evidence.

3. Homogeneity, Stability, and Characterization

Reference materials must be suitable for their intended use. Depending on the material and its intended purpose, producers need appropriate evidence concerning homogeneity, stability, and characterization.

Assessors may review study designs, analytical results, statistical evaluations, and acceptance criteria. For certified reference materials, the producer must also address assigned property values, associated measurement uncertainty, and metrological traceability as applicable.

4. Internal Audits and Corrective Actions

Internal audits help identify weaknesses before the formal assessment. Producers should evaluate relevant management system and technical activities, record findings, and address identified nonconformities.

Corrective actions should address the underlying causes of problems, with follow-up evidence demonstrating whether the actions were effective. This approach supports continual improvement and better assessment readiness.

How to Prepare for an ISO 17034 Assessment

A structured preparation process can reduce avoidable delays and help teams identify areas requiring improvement.

  • Review applicable requirements: Identify the relevant ISO 17034 requirements and accreditation body criteria.
  • Conduct a gap analysis: Compare current practices with applicable requirements and prioritize gaps.
  • Organize technical evidence: Ensure production records, validation information, study results, and reference material certificates are complete and controlled.
  • Evaluate personnel competence: Maintain relevant training, qualification, and authorization records.
  • Complete internal audits: Review implementation, document findings, and verify corrective actions.
  • Prepare staff for interviews: Ensure personnel understand their responsibilities and can explain the procedures they follow.

The objective is to demonstrate effective implementation, not merely to prepare documents for an assessment visit.
