SRD must be compliant with rigorous critical evaluation criteria.

But at least using a template instead of just using a URL ensures that the links from Wikipedia are centralized and hopefully easier to fix. NIST provides 49 free SRD databases and 41 fee-based SRD databases. Note: There is always a risk that NIST may change the structure of the website and the query parameters. So a way of including just about everything would be to use a mask value of FFFF. The current meaning of this field is a hexadecimal number resulting from the sum of the following bits: 1 Gas phase thermochemical dataĨ00 Vibrational and/or electronic energy levels

mask this can be obtained from the URL and determines which sort of data is displayed. The NIST Uncertainty Machine is a web-based software application produced by the National Institute of Standards and Technology ( NIST) to evaluate the measurement uncertainty associated with a scalar or vectorial output quantity that is a known and explicit function of a set of scalar input quantities for which estimates and evaluations of. units either CAL (for calorie-based units) or SI. accessdate this can be useful because the WebBook could change as data is updated. If not present, the ID will be used as a name. name the name of the substance, used for the link name. (eds.) NIST Chemistry WebBook, NIST Standard Reference Database Number 69, National Institute of Standards and Technology, Gaithersburg (MD), (retrieved 2008) id the NIST id for the substance (can be obtained from the URL). Data in the WebBook system are organized by chemical species. The data provided in the site are from collections maintained by the NIST Standard Reference Data Program and outside contributors. An example using all available parameters is the following:Īmmonium chloride in Linstrom, Peter J. The NIST Chemistry WebBook provides users with easy access to chemical and physical property data for chemical species through the internet. To link to a specific substance, the id parameter needs to be supplied. (eds.)

By default, the template produces a generic citation to the WebBook: The NIST Chemistry WebBook was developed in part with funds from the Systems Integration for Manufacturing Applications (SIMA) program at NIST.
