AbstractThese 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.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.

4.1 Purpose—The approval of Guide E1384, concerned with the structure and content of the computer-based patient record, now includes a formal indexing of data elements and a cataloging of the minimal essential value set for these elements. Indexing of these data elements with a unique identifier keyed to its position in the logical structure of Appendix X1 of Guide E1384 now provides a means of cataloging the value sets representing each data element (see Guide E1384). Guide E1239 describes conventions for representing many of the data values for data elements that are included in the more comprehensive listing in Guide E1384. A comprehensive listing of all of the value sets associated with Guide E1384 has not yet been assembled. This specification begins to catalog the representation conventions for a number of these elements and in particular to list the coded values. It is important that this catalog consider the traditionally assigned representations for each of these elements, and it must resolve differences in a manner that introduces systematics and consistency into the representation. The catalog must establish both a global framework consistent with international standardization and with long-term growth, while at the same time maximizing familiar or traditional representations. This standard has been developed with input from many organizations, including government agencies and other standards bodies and professional associations, and as a result of the effort to achieve consistency and comprehensiveness among the data dealt with by various standards efforts.4.2 General Values—Early in the coordination of healthcare information standards an informal body, the Healthcare Information Standards Coordinating Committee (HISCC), identified certain common data element types and agreed upon conventions for representing these data element types in a standard manner. This set the stage for the development of the value sets for the CODED VALUE data type. The status of the standard noncoded data types, and their representations, agreed upon by the HISCC are:4.2.1 Person Names—Guide E1239, Practice E1715, Practice E1744, and HL-7 use the same representation for American and European forms.4.2.2 Addresses—Common format in Guide E1239, Practice E1715, and Practice E1744.4.2.3 Telephone Numbers—Guide E1239 currently uses the same representation with area code enclosed in parentheses and country code preceding the parentheses.4.2.4 Dates—Date and time represented as ANS X3.51-1986/ISO 8601-1988 with years in four digits; time not separated from date by “T” as permitted by ISO 8601.4.2.5 Numbers—Numbers are represented either as integers or fixed point numbers; exponential notation not presently accepted in Guide E1239 or HL-7. Units of Measure by ISO 2955-1983 or ANS X3.50-86.4.2.6 Strings—7-bit ASCII characters; multilingual character sets not yet defined.5AbstractThis specification covers all paper and automated systems related to the identification of the lexicons to be used for the data elements intended to unify the representations for: (1) primary record of care data elements; (2) the data elements identified in other standard statistical data sets; (3) data elements used in other healthcare data message exchange format standards, or (4) in data gathering forms for this purpose; and (5) in data derived from these elements in order that data recorded in the course of patient care be exchangeable and be the source of accurate statistical and resource management data.1.1 This specification covers the identification of the lexicons to be used for the data elements identified in Appendix X1 of Guide E1384. It is intended to unify the representations for: (1) primary record of care data elements, (2) the data elements identified in other standard statistical data sets, (3) data elements used in other healthcare data message exchange format standards, or (4) in data gathering forms for this purpose, and (5) in data derived from these elements in order that data recorded in the course of patient care be exchangeable and be the source of accurate statistical and resource management data. This specification is applicable to all paper and automated systems.
