JOURNAL OF PHYSICAL AND CHEMICAL REFERENCE DATA

The Journal of Physical and Chemical Reference Data (JPCRD) is published by AIP Publishing for the U.S. Department of Commerce National Institute of Standards and Technology (NIST). The journal provides critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. Critical reviews of measurement techniques may also be included if they describe the accuracy of available data in a technical area. Manuscripts reporting correlations of data or estimation methods are acceptable only if they are based on critical data evaluation and if they produce reference data—the best available values for the relevant properties. JPCRD does not publish original experimental measurements, such as those normally reported in the primary research literature, nor review articles of a descriptive or primarily theoretical nature. One source of journal contributions is The National Standard Reference Data System (NSRDS), established in 1963 to coordinate, on a national scale, the production and dissemination of critically evaluated reference data in the physical sciences. Under the Standard Reference Data Act (Public Law 90-396) NIST has the primary responsibility to provide reliable scientific and technical reference data. NIST coordinates several data evaluation centers, located in university, industrial, and government laboratories, as well as within NIST. These laboratories compile and evaluate numerical data on physical and chemical properties retrieved from the world scientific literature. The participants in this NIST-sponsored program, together with similar groups under private or government support, compose the NSRDS. The primary focus of the NSRDS is on well-defined physical and chemical properties of well-characterized materials or systems. An effort is made to assess the accuracy of data reported in the primary research literature and to compile critically evaluated data to serve as reliable and convenient reference sources for the scientific and technical community.
