Reduce risk, improve processes, and capture the accurate and precise data you need with ASTM International Reference Materials.
With access to a wide variety of petroleum products at multiple levels, our reference materials provide highly accurate reference values and very low uncertainty estimates based on test results from labs all over the world.
Reference materials from ASTM International provide a cost-effective solution without sacrificing analytical accuracy – a must for any lab and equipment manufacturer or distributor.
Reference materials are used in the industry for method validation, calibration, and quality control. The use of high-quality and properly matched referenced materials can help you reduce risk, improve processes, validate other QC materials, and capture accurate and precise data to meet business needs.
ASTM Reference Materials are characterized through the use of test results from a network of competent laboratories. In most cases this will range from 20 to over 100 different laboratories.
With access to a wide variety of petroleum products at multiple levels, our reference materials provide highly accurate reference values with very low uncertainty estimates based on test results from laboratories around the world.
Characterization of reference materials is necessary to assign property values to the material. There are a number of approaches that can be taken for characterization including:
Our primary approach to order fulfillment is to establish each customer’s reference material needs in terms of matrix and level allowing ASTM to provide reference materials that meet each customer’s individual needs. These bespoke materials can help you:
The reference material should have a matrix as close as possible to the matrix of the material that will be subjected to the measurement process. For Example — If a laboratory wishes to validate vapor pressure in motor gasoline, then the reference material should be motor gasoline, not another matrix such as crude oil.
The reference material should have properties at the level(s) appropriate to the level at which the measurement process is intended to be used. For Example — Concentration
Quantity and Container Suitability
The quantity of the reference material, the container type, and the container capacity should be in accordance with the test method requirements and include some reserve if necessary. For Example — ASTM D5191 specifies that the only valid container for obtaining samples is 250 mL or 1L containers. ASTM D3606 requires 25mL of reference material.
Acceptable Uncertainty of the Certified Value
The smaller the acceptable uncertainty value is, the more accurate the ARV is under equivalent confidence intervals.
