Further,within
5、 a particular metal or alloy group, different sets of dataelements may be used to identify specific material conditions.1.1.4 Table 1 on Recommended Data Elements and Tables2-17 on values for specific data elements appear at the end ofthis guide.1.2 Some of the data elements in this guide may be use

However, this guide does not attempt todocument the essential and desirable data element for anypurpose except for the identification of metals and alloys incomputerized material property databases. Other purposes,such as material production, material procurement, and mate-ria

Aspecific example is the contractually required report for amaterial property testing series. Such a report may not containall the data elements considered essential for a specificcom

While this guide includes a number of

47、hat areindispensable for uniquely identifying a metal or alloy in acomputerized database. The purpose is to facilitate standard-ized storage and retrieval of the information with a computer,and allow meaningful comparison of data from differentsources.4.2 Many numbering systems for metals and alloys
48、 havebeen developed which are based on their chemical composi-tions. Separate systems have also evolved to describe thethermomechanical condition of metals and alloys in order tonarrow their description. It is the separation into logical dataelements from these complex, historically significant, and
49、overlapping systems of identification that is the challenge inthe identification of metals and alloys within computerizeddatabases.4.3 This guide is intended to provide a common startingpoint for designers and builders of materials property data-bases. This guide generally identifies the contents of thedatabase in terms of data elements, but does not recommendany particular logical or physical database design. A databasebuilder has considerable flexibility in designing a databaseschema, and it is intended that this guide support that flexibil-ity.4.4 It is
