Analytical Reference Materials International Metal Alloy Proficiency Testing Program (PTP)
ISO 17043:2010, Annex A Compliant, Model 2 Scheme
Our unique metal alloy Proficiency Testing Program (PTP) is the only program that measures analytical performance against a CRM’s “Assigned Value”, and has been used in the metals industry for more than 30 years. This PTP was developed as an alternative to typical round-robin style proficiency testing schemes, which only measure performance with non-certified materials. Our PTP is compliant with ISO 17043:2010, Annex A as a Model 2 scheme.
It is important to monitor the quality of your analytical results, as stipulated in the ISO/IEC 17025 laboratory accreditation process. Our PTP gives you that ability with an unbiased and confidential assessment of your analytical performance against peer performance. Whether you have a single-instrument or a multiple-instrument/multiple-technique environment, our PTP is a trouble-free QA program that is traceable to NIST values, and can be easily integrated into your lab processes.
Why choose the Analytical Reference Materials International PTP?
- Large library of materials—over 380 metal alloys and many aluminum alloys
- Participants data compared to assigned value (test samples are actual CRMs)
- Results are returned fast--within 72 hours
- Results presented in a one-page report with a single statistical graph
How it works:
- You select the date and frequency (monthly, quarterly, biannually or annually).
- You choose the type of material by matrix group and sample configuration (solids, chips or pins).
- We send you a blind sample from our stock of CRMs based on your selection.
- You analyze the blind sample, and email or fax your results to us.
- You receive your report within 72 hours. All results are confidential.
Available Matrix Groups:

Your report will include:
- A color-coded Certificate of Performance which compares your results to the actual benchmark data
- A color-coded Control Chart graphically depicting your data compared to the certified average for each element examined
- A Certificate of Analysis confirming that a CRM was used in the test
Value of participation in a proficiency testing program:
- Monitor & improve measurements
- Demonstrate analytical competence
- Develop and train analysts
- Method and instrument validation
