INTERLABORATORY COMPARISONS – Proficiency Testing Provider
SA Quality for Metrology is an accredited Proficiency Testing Provider in the field of calibration.
In accordance with ISO/IEC 17043:2010 standards, we are accredited by the Italian body Accredia with PTP Accreditation Certificate PTP No. 0024P.
According to EA, IAF and ILAC Mutual Recognition Agreements we are authorized to operate at an international level.
Organization of Interlaboratory Comparisons
In order to consistently confirm their performance over time, any testing / calibration laboratory needs to participate periodically in Interlaboratory Comparisons (ILC) – also called Proficiency Testing (PT) – as required by ISO/IEC 17025 standards.
ILCs are effective tools used to assess the performance of specific tests or measurements, and allow for accurate and continuous monitoring. This enables the laboratory to validate its uncertainty statements and ensure the metrological traceability.
Furthermore, according to ISO/IEC 17025 standards, participation in ILCs is a mandatory requirement for obtaining and maintaining specific accreditations for testing or calibration procedures, and may also be requested by partners or customers / clients.
Regardless of the results, participating in ILCs is always advantageous. Positive results provide a guarantee of quality and reliability, instilling confidence in customers / clients. Unsatisfactory results prompt laboratories to improve their procedures and service efficiency.
Our key points of excellence
- Registration for Proficiency Testing is done through our Proficiency Testing Web Portal (PT Portal).
Information and documents are uploaded directly to the PT Portal, eliminating the need for numerous email exchanges with your provider.
- You will always have direct contact with the cycle coordinator.
- All cycle-related information is managed directly on the PT Portal, ensuring maximum transparency.
- We issue a report for each individual participating laboratory, allowing you to access simplified reports specific to your activities.
Organization of Bilateral Interlaboratory Comparisons
In addition to circuit-based tests, we also organize Bilateral Proficiency Testing. In this type of testing, a single participating laboratory is compared to a reference laboratory.
We organize Bilateral Comparisons upon request, when the requesting laboratory needs to obtain a specific accreditation or when there are no other laboratories performing the same type of calibration.
If you wish to request a Bilateral Comparison, please send us an email specifying:
- Type of instrument.
- Calibration methodology.
We will provide you with a quotation and information regarding participation methods.
Interlaboratory Comparisons program and registration
Below we present the updated ILCs calendar in which you can participate. By clicking on SHOW you can access the description card for the respective comparison, which includes technical information and participation methods. From each card you can also download the participation form, which shall be completed and uploaded to the PT Portal upon registration.
To register for an ILC, you will need to create an account that will grant you access to the reserved area of our website and the PT Portal. On the portal you can autonomously register for comparisons, with no need to send us requests or attached documents by email.
If you want to participate in a Bilateral Interlaboratory Comparison, please send us a request by email, specifying the type of instrument and calibration methodology involved in the comparison. We will provide you with a quotation and information regarding participation methods.
