In the world of testing and calibration, the accuracy and reliability of results are non-negotiable. One key way to ensure quality and build trust is through ISO 17043 accreditation—a globally recognized standard that outlines the general requirements for Proficiency Testing Providers (PTPs). Whether you're a lab seeking credibility or a customer depending on accurate test outcomes, understanding ISO 17043 is essential.

What Is ISO 17043?

ISO/IEC 17043:2010 specifies the general requirements for the competence of providers of proficiency testing schemes. Proficiency testing involves multiple laboratories analysing the same samples, with the results compared to assess each lab’s performance.

The standard ensures that PT providers operate with a high level of technical competence and robust quality management systems. Accreditation is typically granted by recognized national or international bodies, confirming that the provider meets all necessary criteria.

Who Needs ISO 17043?
ISO 17043 is designed for a variety of organizations, including:
• Proficiency testing providers
• Calibration ...
... and testing laboratories (as participants)
• Reference material producers
• Regulatory agencies
• Accreditation bodies
Any organization involved in the quality assurance of test or calibration results can benefit from engaging with ISO 17043—either as a provider or participant.

Benefits of ISO 17043 Accreditation

Improved Credibility and Confidence: ISO 17043 Accreditation demonstrates a PT provider’s technical competence and enhances the credibility of the testing process. It reassures participants and stakeholders that results are valid, reliable, and unbiased.

Regulatory and Contractual Compliance: In many sectors, participation in ISO 17043-accredited PT schemes is a legal or contractual requirement. Accreditation helps organizations meet these obligations more efficiently.

Enhanced Quality Assurance: ISO 17043 helps identify inconsistencies or issues in laboratory performance, encouraging continuous improvement and better overall quality assurance.

Global Recognition: Because ISO 17043 is internationally recognized, accreditation supports international trade, compliance, and cross-border collaboration.

Competitive Advantage: Being ISO 17043-accredited distinguishes a provider in a competitive market, making them more attractive to clients and partners looking for trustworthy services.

Key Requirements of ISO 17043
To achieve ISO 17043 accreditation, PT providers must meet specific requirements in both management and technical areas:

• Management System: The provider must have documented procedures, policies, and a quality manual that support the consistent operation of PT schemes.
• Technical Competence: Personnel must be qualified, and facilities and equipment should be suitable for the scope of testing.
• Scheme Design: PT schemes must be carefully planned with clear objectives, test item homogeneity, and appropriate statistical analysis.
• Operation & Evaluation: The provider must ensure proper distribution of test items, data collection, evaluation, and reporting of results with confidentiality.

The ISO 17043 Accreditation Process
Achieving ISO 17043 accreditation involves several key steps, each critical to demonstrating the provider's capability.

Step 1: Gap Analysis and Preparation
Step 2: System Documentation
Step 3: Internal Audit and Management Review
Step 4: Application to Accreditation Body
Step 5: On-Site Assessment
Step 6: Corrective Actions
Step 7: Accreditation and Surveillance

ISO 17043 accreditation plays a critical role in maintaining trust, transparency, and quality within proficiency testing. For organizations offering PT schemes, accreditation not only validates your expertise but also enhances your standing in the global market.

For laboratories, participating in ISO 17043-accredited programs ensures you're benchmarking your performance against recognized standards—an essential part of delivering consistent, high-quality results.
