NIST Standard Reference Materials® (SRMs®) are used by industry, government, and academia to ensure the highest quality measurements. This catalog lists over 1300

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.

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 1 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+ %)

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

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

1 High level radiopharmaceutical SRMs are distributed through a program with the exception of technetium-99m.

This program includes:

Distribution of radioactivity Standard Reference Materials (usually a high level [107 Bq to 1010 Bq] and low level [106 Bq to 108 Bq] pair of sources), for quantification, to sponsoring participating companies ten times per year. Two "open" months per year when the sponsors have the opportunity to send in sources of their choice for calibration.

For the more information, please contact Daniel Golas, the program's Project Manager, at NIST (301) 975-5540. n Technetium-99m is also available to purchasers of low level radiopharmaceutical SRMs.

Radon Emanation Standard

This SRM is intended for the calibration of radon-222 measuring instruments. It consists of a small heat-sealed polyethylene cylinder containing approximately 0.35g of radium-226 solution. The SRM is calibrated in terms of the radium-226 activity and in terms of the emanation fraction of the radon-222 under specified conditions.
