Accurate measurements are the backbone of reliable scientific work. But calibration isn’t just about precision — it’s critical for safety, compliance, and credibility. At DH Lab, our calibration services are accredited to ISO/IEC 17025, the international standard for laboratory competence. This gives you assurance that your results are technically sound and globally accepted — whether you’re operating in Northern Ireland or the Republic of Ireland.
- What does ISO/IEC 17025 accreditation mean?
ISO/IEC 17025 is the leading international standard for testing and calibration laboratories. It ensures that labs demonstrate technical competence, impartiality, and consistent operation.
DH Lab is accredited to ISO/IEC 17025 by UKAS (United Kingdom Accreditation Service), the UK’s sole national accreditation body. UKAS is a signatory to the European co-operation for Accreditation (EA) Multilateral Agreement (MLA). This means that certificates issued by UKAS-accredited labs are recognised and accepted across Europe — including Ireland — and internationally through ILAC (International Laboratory Accreditation Cooperation) agreements.
- The benefits of ISO/IEC 17025 accredited calibration
| Benefit | Why it matters |
| Confidence | Accreditation ensures results are accurate, impartial, and delivered by technically competent labs. |
| Reduced risk | Minimises chances of product failure, rework, or resource waste. |
| Global acceptance | ISO/IEC 17025 is internationally recognised, supporting cross-border compliance and trade. |
| Regulatory compliance | Meets rigorous requirements for legal, industry, and audit standards (ISO 9001, MHRA, aerospace). |
| Continuous improvement | Accredited labs undergo regular audits, driving quality and accountability. |
- What ISO/IEC 17025 accreditation includes
- Traceable, standardised measurement methods
- Qualified technicians and controlled testing environments
- Full traceability to national/international standards
- Independent audits and certified documentation
- Is non-accredited calibration enough?
Non-accredited calibration may appear cost-effective but lacks the assurance of internationally recognised procedures and impartial verification. In highly regulated industries — such as aerospace, defence, pharmaceuticals, diagnostics, and food safety — calibration must meet formal accreditation requirements. Without ISO/IEC 17025 accreditation, compliance — and confidence — may be compromised.
In Summary
Using an ISO/IEC 17025 accredited lab means:
- Greater confidence in the accuracy and reliability of your results
- Reduced compliance risks and operational delays
- International recognition — including across the island of Ireland
- A commitment to ongoing quality and best practices
At DH Lab, we deliver calibration services you can trust: accredited to ISO/IEC 17025, traceable to national standards, and supported by expert technical staff and full documentation.
