Find standards around
the method you need to support.
Choose the regulatory, standard-method or QA/QC group that best matches your laboratory requirement to explore relevant reference-material applications and supporting manufacturers.
ISO / IEC 17025
Reference materials and quality-control materials supporting calibration, verification, method validation, traceability and proficiency-testing activities in accredited or accreditation-seeking laboratories.
Related ManufacturersASTM Methods
Reference standards for petroleum, oil, metals, alloys, sulfur, lubricants and industrial materials tested under ASTM-based laboratory workflows.

Related ManufacturersUSP / Pharmaceutical
Reference standards supporting pharmaceutical testing, residual solvents, impurities, assay, verification and analytical method-validation requirements.
Related ManufacturersAOAC Methods
Analytical standards for food, agriculture, pesticide residues, contaminants, nutrients and other compositional or food-safety testing applications.
Related ManufacturersMining / Geological QA
Reference materials for ore grade control, geochemical exploration, XRF and ICP validation, mining QA/QC and geological-analysis workflows.
Related ManufacturersA reference material should support the purpose of the method — not only contain the correct analyte.
Standard methods and quality frameworks define more than a test name. They can influence calibration, validation, traceability, matrix expectations, acceptance criteria and the documentation required to support reliable results.
The method scope defines the analytical problem.
Sample type, analyte, technique and measurement range should align with the actual method or laboratory procedure.
Quality systems may require documented traceability.
CRM certificates, uncertainty and reference values can become important evidence in calibration and validation activities.
Method validation requires fit-for-purpose evidence.
Accuracy, recovery, bias, precision and other performance characteristics can depend on the reference material used.
Routine quality control may need a different material from calibration.
Calibration standards, independent QC materials, CRMs and PT materials can serve different quality-control roles.
The method is the starting point — then the technical requirement becomes specific.
After the standard or quality requirement is known, reference-material selection should still be refined using the sample matrix, analyte, concentration range, instrument technique, preparation route and intended quality use.
ISO/IEC 17025, ASTM, EPA, USP, AOAC, mining QA/QC, internal method or another quality framework.
Water, petroleum, metal, ore, soil, food, pharmaceutical or another real sample type.
Element, compound, contaminant, residue, impurity, nutrient or another analytical target.
ICP, ICP-MS, XRF, OES, AA, GC, HPLC or another measurement technique.
Concentration level, calibration range and the associated sample-preparation workflow.
Calibration, validation, verification, routine QC, proficiency testing, audit or accreditation support.
Frequently asked questions about
reference materials by standard method.
Method-based navigation helps narrow the search, but final suitability still depends on the complete analytical and quality requirement.
Does ISO/IEC 17025 require laboratories to use CRM in every test?
Reference-material needs depend on the laboratory activity, method, calibration, validation, traceability and quality-control objective. The appropriate material should be selected around the specific use rather than assumed from the accreditation standard alone.
Can one reference material support both ASTM and internal laboratory methods?
Potentially, if its matrix, analytes, concentration range, certification and intended use are technically suitable for both applications. Suitability should be evaluated against each method requirement.
What information should I provide when selecting a standard for a specific method?
Useful information includes the method number or standard, sample matrix, target analytes, concentration range, instrument technique, preparation route and intended use such as calibration, validation or QC.
What if the required standard is not available from a usual manufacturer?
Alpha Prime Lab can help search alternative manufacturers and, where appropriate, evaluate matrix-matched or custom-reference-material options.
