NIST Standard Reference Materials® (SRMs®) are used by industry, government, and academia to ensure the higliest 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.

EPA: Organic Compounds Related to Water Analysis

These SRMs are intended primarily for the calibration of instrumentation and validation of methods for volatile or semivolatile organic compound determinations. Because of its miscibility with water, each SRM can also be used to fortify aqueous samples with known amounts of the organic compound. These SRMs were developed by the NIST Analytical Chemistiy Division (ACD) primarily to support the Chemical Calibration Providers of the Proficiency Testing Program

with support by the U.S. Environmental Protection Agency (EPA).

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 ram); wire (2 ram 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 coraraercially available substance of purity 100 % + 0.02 % (Purity 99-98-1- %)

Working Standard: a coraraercially 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) 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,
