Our 17025 Accreditation

ISO 17025 Accreditation

What Is ISO/IEC 17025 Accreditation?

ISO/IEC 17025 accreditation is an internationally recognized verification that a laboratory has demonstrated the technical competence, quality systems, and measurement capabilities required to perform accurate and reliable calibrations and testing.

Transcat Pipettes is an accredited laboratory, certified by the ANSI National Accreditation Board (ANAB). Pipettes.com calibration competency is verified by our accreditation to all the industry standards, including:

ISO/IEC 17025:2017

ISO/IEC 17025 is the global standard for testing and calibration laboratory competence. It establishes requirements for technical competency, quality management, equipment control, measurement traceability, uncertainty analysis, and continuous improvement. Accreditation to ISO/IEC 17025 helps ensure that calibration results are accurate, reliable, and recognized worldwide.

ISO 8655:2022

ISO 8655 is the international standard that specifically defines the requirements and test methods used for calibrating piston-operated pipettes and related liquid handling instruments. The standard establishes procedures for verifying pipette performance, environmental controls, testing conditions, maximum permissible errors, and measurement uncertainty requirements. Compliance with ISO 8655 helps ensure accurate and repeatable liquid handling measurements.

ANSI/NCSL Z540.3

ANSI/NCSL Z540.3 is a measurement assurance standard that establishes requirements for calibration systems used throughout industry. The standard emphasizes measurement risk management, traceability, uncertainty analysis, and decision rules for determining compliance. Organizations operating in regulated industries often use ANSI/NCSL Z540.3 to strengthen confidence in measurement processes and calibration results.

USP Chapter <41> Balances

USP Chapter <41> establishes requirements for the use and performance verification of balances within pharmaceutical and laboratory environments. Because gravimetric analysis is the primary method used for pipette calibration, balance performance is a critical component of calibration accuracy. Compliance with USP requirements helps support reliable mass measurements used during calibration activities.

What does ISO/IEC 17025 measure?

  • Individual competence of staff to perform.
  • Use of proper equipment and its maintenance and calibration.
  • Having in place sufficient quality assurance and quality control processes.
  • Sampling in place to the appropriate degree.
  • Procedures in place for their inspection/testing/calibration.
  • Validated methods for obtaining data.
  • The ability to report and record accurate data.
  • Traceability to national standards whenever appropriate.
  • Proper environmental conditions to perform testing/calibration/inspection

What evidence does an accredited laboratory have to prove its accreditation status?

Accredited laboratories have both a Certificate of Accreditation (stating ISO/IEC 17025 accreditation has been granted) and they have a “Scope of Accreditation”, this scope is determined by the laboratory, and assessment activities will be focused on those processes that affect this scope.

ISO/IEC 17025 vs. ISO 9001

ISO 9001 is applicable to many businesses and industries, while ISO 17025 is specifically valuable for testing and calibration.

Even though labs can be certified and audited (or registered) to internal management systems such as ISO 9001 (the standard typically used in manufacturing and service type organizations for managing the quality of their product or services) – ISO 9001 DOES NOT evaluate technical competence – this means that evaluation of ISO 9001 won’t ensure that the testing/calibration/inspection data provided is accurate, competent, or reliable. ISO/IEC 17025 Accreditations fill the “gap” of technical competence not addressed by ISO 9001.

Where ISO 9001 covers the facility, ISO/IEC 17025 specifically covers methods or functions detailed in each laboratory’s “Scope of Accreditation”.

Frequently Asked Questions About Pipette Calibration Accreditation

What is ISO/IEC 17025 accreditation?
ISO/IEC 17025 accreditation is an internationally recognized standard that demonstrates a laboratory's technical competence to perform calibration and testing activities. Accreditation verifies that a laboratory operates according to documented quality procedures, uses validated methods, maintains traceability to recognized standards, and can produce accurate, reliable, and repeatable measurement results. For calibration laboratories, ISO/IEC 17025 is considered the benchmark for technical competency and measurement quality.
Can you calibrate both manual and electronic pipettes?
Yes. Our technicians service a wide range of both manual and electronic pipette models.
Why is ISO 17025 important for pipette calibration?
ISO/IEC 17025 accreditation helps ensure that pipette calibration results are accurate, traceable, and technically defensible. Accredited laboratories must demonstrate staff competency, validated calibration methods, controlled environmental conditions, measurement uncertainty analysis, and ongoing quality assurance. This provides confidence that calibrated pipettes are performing within specification and that measurement data can be trusted for critical laboratory applications.
What is the difference between ISO 17025 and ISO 9001?
ISO 9001 focuses on the effectiveness of a company's quality management system and customer satisfaction processes. ISO/IEC 17025 goes further by evaluating the technical competence of a laboratory to perform calibration and testing activities. While ISO 9001 helps ensure consistent business operations, ISO/IEC 17025 specifically verifies that a laboratory can generate accurate, reliable, and traceable measurement results.
How does ISO 17025 improve measurement accuracy?
ISO/IEC 17025 improves measurement accuracy by requiring laboratories to follow validated calibration procedures, maintain calibrated equipment, control environmental conditions, calculate measurement uncertainty, and demonstrate staff competency. These requirements reduce measurement variability and help ensure that calibration results remain consistent, repeatable, and traceable to recognized standards.
What proof of accreditation should a calibration provider provide?
An accredited calibration provider should be able to provide a current Certificate of Accreditation and a Scope of Accreditation. The certificate confirms that accreditation has been granted by an approved accrediting body, while the scope defines the specific calibration services, measurement ranges, and uncertainties for which the laboratory has been assessed and accredited. Customers should review both documents when evaluating a calibration provider.
Is Transcat Pipettes ISO/IEC 17025 accredited?
Yes. Transcat Pipettes operates ISO/IEC 17025 accredited laboratories and maintains Certificates and Scopes of Accreditation that document the calibration capabilities assessed by its accrediting body. Accreditation verifies that Transcat Pipettes has demonstrated the technical competence, quality systems, and measurement processes required to provide accurate and reliable calibration services.
Industry Standards Supporting Calibration Quality
Transcat Pipettes maintains a quality program built around internationally recognized calibration and measurement standards. Each standard serves a different role in ensuring the accuracy, reliability, and traceability of laboratory measurements.
