The ISO 10012 standard on measurement management systems is about to be updated for the first time since 2003, with the new edition expected in early 2026. This update is more than just a technical refresh; it is widely viewed as an important milestone for industry. The revision is expected to increase the visibility and importance of measurement management systems, and many organizations, including suppliers in regulated or quality-critical sectors, may increasingly be required to demonstrate compliance with or even formal certification against ISO 10012 in the future.
The revision brings ISO 10012 in line with today’s management system structure and introduces a stronger, risk-based approach. It also adds valuable practical guidance on topics such as calibration interval optimization, measurement uncertainty, and decision rules. At the same time, the revision highlights the strategic role of measurement in ensuring confidence, compliance, and operational performance – not just in laboratories, but across entire organizations.
For calibration professionals, this means clearer requirements, improved alignment with standards like ISO 9001 and ISO 14001, and stronger tools to manage measurement-related risks in everyday work. The expected rise in certification activity may also elevate the status of measurement management as a core component of organizational quality systems.
Beamex has actively contributed to the development of this new edition, helping ensure that the practical needs of calibration professionals are represented.
In this article, we’ll explain what ISO 10012 is, why the update was needed, what’s new compared to the 2003 version, and – most importantly – what the changes mean in practice for people managing and performing calibrations.
This article also includes insights from one of the standard’s contributors, Alistair Norwood, along with a link to his detailed explanatory white paper.

ISO 10012: Measurement management systems – Requirements for measurement processes and measuring equipment is the international standard for managing measurement activities. Its purpose is to ensure that measurements made within an organization are reliable, traceable, and suitable for their intended use. In practice, it provides a structured approach to managing measuring equipment, calibration, and measurement processes.
Version history:
Since 2003, industry and management system standards have both evolved significantly. ISO 9001 (Quality Management Systems) and ISO 14001 (Environmental Management Systems) have moved to a high-level structure (Annex SL) and emphasized risk-based thinking. Technology, digitalization, and data-driven calibration methods have also changed the way organizations manage measurement processes.
Updating ISO 10012 makes it:
The 2003 edition had the following main sections:
The 2026 draft follows the modern Annex SL structure, with clauses 4–10:
Despite the new structure, the essence of ISO 10012 remains:
For quality and operations leaders:
For metrology managers:
For calibration technicians and engineers:
For procurement/supplier quality:
ISO 10012 is not a replacement for ISO 9001 or ISO 14001, but it supports them by ensuring reliable measurements that underpin quality and environmental performance.
The new edition of ISO 10012 adds valuable guidance on how to determine the most appropriate calibration intervals for measuring equipment. Instead of using fixed intervals (for example, every 12 months), organizations are encouraged to use a more analytical, data-driven approach. Several methods are highlighted:
Practical impact: By moving away from a one-size-fits-all approach, organizations can reduce the number of unnecessary calibrations and save costs while maintaining confidence in measurement results. This makes calibration programs more efficient and defensible during audits.
The standard offers concise guidance on how to calculate and apply measurement uncertainty in decision-making. Importantly, it emphasizes that pass/fail (conformity) decisions should not be made solely by comparing the measured value to the tolerance. Instead, the measurement uncertainty must be taken into account. This ensures that organizations properly manage the risk of false acceptance (declaring something in tolerance when it is not) and false rejection (declaring something out of tolerance when it is in fact acceptable).
One practical method is guard banding, where the acceptance limits are tightened by an amount related to the measurement uncertainty. This reduces the chance of false acceptance by ensuring only results that are clearly within tolerance are accepted.
Practical impact: Organizations can make better and more defensible decisions when results are borderline, avoiding both false confidence and unnecessary rejections.
Annex D provides detailed guidance on how to establish decision rules and manage risks such as false accept and false reject. Organizations are expected to define and document the decision rule they use, and the rule should clearly state how uncertainty is factored into conformity assessment.
The annex also emphasizes the use of the Test Uncertainty Ratio (TUR). TUR is the ratio of the tolerance of the item being calibrated to the expanded uncertainty of the calibration process. In practice, a higher TUR means greater confidence that a measurement result close to the tolerance limit is still reliable.
Beamex has been part of the ISO working group revising the standard, through the contribution of Christophe Boubay and Gautier Triboulloy, both working at Beamex France.
“The revision of ISO 10012 brings the standard in line with today’s management system practices and risk-based thinking. The aim has been to make it clearer and more practical for organizations that rely on accurate measurements in their operations. It brings metrology and calibration to the status they deserve, as a strong part of every industry’s quality system, supporting a safer and less uncertain world.”
“By adding guidance on topics like calibration interval optimization, uncertainty, and decision rules, the new edition gives calibration professionals stronger tools for managing risk and ensuring confidence in results.”

To help explain why the updated ISO 10012 is such a significant development, we asked Alistair Norwood, a long-standing contributor to the standard, to share his perspective. Alistair is a Committee Member of ISO 10012, a member of ISO QS3, Chair of BSI QS3 (quality standards) and BSI SS6 (statistical metrology), and works as a metrology Subject Matter Expert at Sellafield in Cumbria. Alistair is also a a long term user of Beamex calibration ecosystem.
“The new measurement standard ISO 10012 doesn’t prescribe the procedures behind how an organisation makes a measurement it goes much further and defines the thinking and the company structure that must go into making a measurement. A washing machine manufacturer and a military valve supplier will reach different answers, but both must follow the same disciplined approach to risk and measurement integrity.”
“The standard is one of the biggest shifts in how a company carries out measurement. In the updated ISO 10012 measurement is no longer seen as only a laboratory activity. Measurement becomes a company-wide exercise, involving the whole company from management and design to procurement to production. Each area within an organization has a role in ensuring measurement integrity.”
Alistair Norwood, Committee Member of ISO 10012, Metrology Subject Matter Expert, Sellafield

Do I need ISO/IEC 17025 if I follow ISO 10012?
Not necessarily. ISO/IEC 17025 is for testing/calibration laboratories, while ISO 10012 covers an organization-wide measurement management system.
Will certification become mandatory?
The standard itself doesn’t mandate certification, but the new edition makes third-party certification possible. Whether it becomes expected depends on industry requirements.
How do I set decision rules in practice?
You should define decision rules based on customer requirements, regulatory expectations, and acceptable risk levels. The annex provides guidance for doing this.
What data do I need for interval optimization?
You will need historical calibration data, drift analysis, and data on equipment usage patterns.
The new edition of ISO 10012 marks a significant step forward for calibration and measurement professionals. It makes the standard more relevant, more practical, and better aligned with modern management systems.
For organizations, the update is both a challenge and an opportunity: a challenge in terms of updating systems and processes and an opportunity to strengthen confidence in measurements, improve efficiency, and demonstrate competence.
