The Key to Internationally Valid, Reliable, and Scientific Testing

The TS EN ISO/IEC 17025 standard is an internationally recognized standard that defines the quality management systems and technical competence of testing and calibration laboratories. It ensures that both public and private laboratories operate in line with principles of accuracy, traceability, and reliability.

The accuracy, repeatability, and international acceptance of analyses conducted in laboratories are critically important for quality management systems. At this point, TS EN ISO/IEC 17025 serves as a cornerstone for testing and calibration laboratories. This standard provides a framework ensuring that laboratories operate according to universally accepted principles, strengthening scientific integrity in every step.
Why Is This Standard So Important?

⇒ Ensures Scientific Accuracy and Reliability

The validity of analyses is the foundation of laboratory success.

TS EN ISO/IEC 17025 guarantees that tests carried out by laboratories are scientifically valid, repeatable, and impartial. It ensures that every part of the process—from equipment used, methods applied, to personnel competence—is strictly controlled. As a result, measurement uncertainties are minimized, test results become repeatable, and conclusions are scientifically defensible. This means that outcomes confirming whether a product meets quality or safety criteria can be obtained with consistent reliability. This principle of accuracy is especially vital in sectors such as food, cosmetics, environmental science, and biotechnology, which directly impact human health

⇒ Provides International Recognition

Eliminates the need for redundant testing in foreign markets.

Test reports from a laboratory accredited with ISO 17025 are accepted globally thanks to mutual recognition agreements such as those under ILAC (International Laboratory Accreditation Cooperation). This spares companies from repeating tests in different countries, saving both time and money. This is a critical advantage for exporting companies, as products can be introduced to the global market without additional testing requirements.

⇒ Facilitates Legal Compliance

Ensures transparency and traceability in meeting regulations.

Authorities such as the Turkish Ministry of Health and the Ministry of Environment, Urbanization and Climate Change prefer laboratories accredited with ISO 17025 for product analysis. The standard’s required quality management system provides a robust foundation for compliance with both national and international regulations. Audits are conducted transparently, systematically, and with full traceability. Thanks to traceable records of analysis history, laboratories are protected during inspections. The accreditation process also contributes to reducing legal risks.

⇒ Boosts Customer Confidence and Brand Value

Establishes a transparent, impartial, and trustworthy laboratory structure.

Customers want to know that their product analyses are carried out by independent and competent laboratories. Working with a laboratory accredited with ISO 17025 provides strong assurance that the results are high-quality, reliable, and valid. This directly enhances brand value. The standard certifies that test results are not only technically accurate but also produced impartially. This increases customer loyalty and highlights the professionalism of the brand.

⇒ Promotes a Culture of Continuous Improvement

Brings dynamism to quality systems and reduces error risks.

The ISO 17025 framework requires that every operation be documented, reviewed, and improved when necessary. This allows laboratories to manage not just their current operations but also their future development. With internal audits, personnel competency checks, calibration monitoring, and thorough documentation processes required by the standard, laboratories continuously evolve. This systematic approach reduces error rates and boosts efficiency—fostering a competitive, modern, and innovative laboratory culture.

Frequently Asked Questions

Is ISO 17025 mandatory for every testing laboratory?
Not mandatory, but it offers significant advantages in terms of product safety, regulatory compliance, and customer trust.

How long does the ISO 17025 accreditation process take?
It depends on the laboratory's level of preparedness. For a lab with an established quality management system, the process typically takes 6 to 12 months.

Should we choose ISO 17025 or ISO 9001?
ISO 9001 covers general quality management, while ISO 17025 specifically addresses the technical competence of testing and calibration laboratories. For laboratories, ISO 17025 is the more specialized and appropriate choice.

At Cosming Laboratory, we provide the full confidence that comes with ISO 17025 accreditation.
