    ASTM E204

    Abstract

    These practices cover a data system comprising procedures for the identification of individual chemical substances using infrared absorption spectroscopy and band indexes of spectral data. Although this data system is in use world wide as the largest publicly available data base, it does not represent the optimum way to generate a new data base with the most modern computerized equipment. In addition, the use of these practices requires encoded data and appropriate data handling equipment. The index data, which are available on magnetic tape, include codes for spectral data of chemical substances, chemical-structure classification, empirical formula, melting or boiling point, and serial number reference. Codes on sample state, wavelength intervals of strongest bands, and no-data areas are included as well.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 These practices cover a data system generated from 1955 through 1974. It is in world-wide use as the largest publicly available data base. It is recognized that it does not represent the optimum way to generate a new data base with the most modern computerized equipment.

    1.2 These practices describe procedures for identification of individual chemical substances using infrared absorption spectroscopy and band indexes of spectral data. Use of absorption spectroscopy for qualitative analysis has been described by many (), but the rapid matching of the spectrogram of a sample with a spectral data in the literature by use of a band index system designed for machine sorting was contributed by Kuentzel (). It is on Kuentzel's system that the ASTM indexes of absorption spectral data are based.

    1.3 Use of these practices requires, in addition to a recording spectrometer and access to published reference spectra, the encoded data and suitable data handling equipment.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
