Our CRMs are produced from commercially available material analyzed by participating laboratories that are members of ARMI’s Inter-Laboratory Analysis Program (ILAP). The ILAP laboratories utilize ASTM standards to produce the analytical and statistical data used to calculate CRM certified values and 95% confidence intervals. As a result, we produce true CRMs of the highest quality yielding consistent, reproducible and reliable results for industry. Furthermore, ARMI’s Certificates of Analysis contain all of the required and necessary informational disclosures and evidence that the CRMs are traceable to NIST values.
We have produced Certified Reference Materials (CRMs) for the metals industry since 1984. Our CRM inventory includes the following matrices:
