NIST Standard Reference Materials® (SRMs®) are used by industry, government, and academia to ensure the highest quality measurements. This catalog lists over 1100

individual reference materials produced and sold by NIST, each with carefully assigned

values for chemical composition and physical properties. SRMs find use in calibrating instruments and in assuring the long-term integrity of quality assurance programs. They are also key mechanisms for verifying important measurement results and in developing new measurement methods. SRMs provide users with tools to assist in establishing traceability of measurement results to NIST.

Each SRM comes carefully packaged with documentation containing assigned values with stated

uncertainties and a material safety data sheet, if applicable. Details on use, stability, and NIST

analytical methods are also included.

Human Serum

NIST has a number of human serum based SRMs shown in the table below. These are intended to be used as accuracy

checks to determine if a measurement system is in control. If they are to be used as control materials or as calibrators, one must be sure that these materials are commutable with fresh serum in the measurement system. The SRMs in frozen serum are generally more commutable across the various commercial systems than are the lyophilized materials. However, the lyophilized materials may work as well as the frozen materials when analyzed with more robust field methods or with higher order reference measurement procedures.

Fine Gold Standards

These RMs are a series of fine gold and gold bullion products developed and certified by the Royal Canadian Mint (RCM),

Ottawa, Canada and distributed by NIST. The fine gold RMs are primarily intended for use as calibration standards

for the determination of trace elements by solid sample spectrometric methods; the gold bullion RMs are primarily intended for use as quality control check standards for fire assay There are five sets of RMs in the gold bullion series (RMs 8068-8082) available in three forms: disc (25 mm diameter x 20 mm); wire (2 mm diameter); and foil (35 mm x 40 mm x i mm). There are six sets of RMs in the fine gold series (RMs 8050-8067) available in three forms: block (25 mm x 25 mm x 2.5 mm); wire (2 mm diameter); and turnings (25 g).

Stoichiometric Standards

These SRMs are defined as primary, working, and secondary standards in accordance with recommendations of the Analytical Chemistry Section of the International Union of Pure and Applied Chemistry [Ref. Analyst 90, 251 (1965)]

.

These definitions are as follows:

Primary Standard: a commercially available substance of purity 100 % + 0.02 % (Purity 99.98-1- %)

Working Standard: a commercially available substance of purity 100 % ± 0.05 % (Purity 99- 95-i- %)

Secondary Standard: a substance of lower purity which can be standardized against a primary grade standard

a) SRMs 4971, 4972, and 4973 are intended for the calibration of radon-222 measuring instruments. They consist of small

heat-sealed polyethylene cylinders containing approximately 0.2 g of radium-226 solution. These SRMs are calibrated in terms of radium-226 activity and in terms of the emanation fraction of the radon-222 under specified conditions.

a) This SRM replaces SRM 4990, which has been in use in radiocarbon-dating laboratories since 1958. The material is part of a 450 kg lot of oxalic acid that was prepared by fermentation of French beet molasses from the 1977 spring, summer, and fall harvests. The ratio of the massic activity of SRM 4990C to that of SRM 4990, and the mass spectrometric ratios of carbon-13

to carbon- 12 in each, were measured by eleven international carbon-dating laboratories in an intercomparison organized by

L.M. Cavallo and W.B. Mann. See Proceedings of the 11th International Radiocarbon Dating Conference, M. Stuiver and R. Kra,
