1.1本指南涵盖了计算机化材料性能数据库中金属和合金的识别。它建立了用于唯一识别和描述特定金属或合金样品以及识别给定金属或合金的属性的基本和理想数据元素。 1.1.1本指南不一定提供足够的数据元素来描述焊接金属、金属基复合材料或连接金属。 1.1.2本文中确定的数据元素并非与每个金属或合金组都密切相关。 1.1.3根据特定于该金属或合金组的条件或应用，也可在给定金属或合金组内应用不同的数据元素集。此外，在特定金属或合金组内，可以使用不同的数据元素集来识别特定的材料条件。 1.1.4关于推荐数据元素和特定数据元素值的表1见本指南末尾。 1.2本指南中的一些数据元素可能对其他目的有用。然而，本指南不试图记录用于任何目的的必要和可取的数据元素，除非在计算机化材料特性数据库中识别金属和合金。其他用途，如材料生产、材料采购和材料加工，每种用途可能有不同于本指南所涵盖的材料数据报告要求。一个具体的例子是合同要求的材料性能测试系列报告。此类报告可能不包含对特定计算机化数据库至关重要的所有数据元素；相反，本指南可能不包含合同测试报告所需的所有数据元素。 1.3作为采购过程一部分进行的材料测试的结果通常用于确定是否符合规范。虽然本指南包括许多测试结果数据元素，但此类数据元素仅用于材料识别。 1.4合同测试结果（如认证测试结果）的报告应遵循材料规范中所述的要求，或买方和制造商之间达成的协议。 1.5本指南包含与材料试验结果相关的数量有限的数据元素。这些数据元素用于材料识别目的，并不打算取代指南中列出的更详细的数据元素集，例如涵盖金属机械试验数据记录格式的指南E 1313。 出于材料识别目的，本指南中的数据元素包括通常从单个样本测试总体中得出的典型、标称或汇总特性。如果特定数据库系统的范围允许，该系统可以提供本指南中给出的材料识别数据元素与根据与特定测试方法对应的其他指南记录的单个样本测试结果之间的链接。 1.6材料类别——电弧焊接见ANSI/AWS A9.1-92，聚合物见指南E 1308，复合材料见指南E 1309，纤维、填料和芯材见指南E 1471。ASTM委员会E49正在为其他材料类别制定指南。

1.1 This guide covers the identification of metals and alloys in computerized material property databases. It establishes essential and desirable data elements that serve to uniquely identify and describe a particular metal or alloy sample as well as properties that identify a given metal or alloy in general. 1.1.1 This guide does not necessarily provide sufficient data elements to describe weld metal, metal matrix composites, or joined metals. 1.1.2 The data element identified herein are not all germane to every metal or alloy group. 1.1.3 Different sets of data elements may also be applied within a given metal or alloy group depending on conditions or applications specific to that metal or alloy group. Further, within a particular metal or alloy group, different sets of data elements may be used to identify specific material conditions. 1.1.4 Table 1 on Recommended Data Elements and on values for specific data elements appear at the end of this guide. 1.2 Some of the data elements in this guide may be useful for other purposes. However, this guide does not attempt to document the essential and desirable data element for any purpose except for the identification of metals and alloys in computerized material property databases. Other purposes, such as material production, material procurement, and material processing, each may have different material data reporting requirements distinct from those covered in this guide. A specific example is the contractually required report for a material property testing series. Such a report may not contain all the data elements considered essential for a specific computerized database; conversely, this guide may not contain all the data elements considered essential for a contracted test report. 1.3 Results from material tests conducted as part of the procurement process are often used to determine adherence to a specification. While this guide includes a number of test result data elements, such data elements are included in this guide only for the purposes of material identification. 1.4 Reporting of contracted test results, such as certification test results, shall follow the requirements described in the material specification, or as agreed upon between the purchaser and the manufacturer. 1.5 This guide contains a limited number of data elements related to material test results. These data elements are for material identification purposes and are not intended to replace the more detailed sets of data elements listed in guides such as Guide E 1313 covering data recording formats for mechanical testing of metals. For material identification purposes, the data elements in this guide include typical, nominal, or summary properties normally derived from a population of individual specimen tests. If warranted by the scope of a particular database system, the system might provide links between the material identification data elements given in this guide, and the individual specimen test results recorded in accordance with other guides corresponding to particular test methods. 1.6 Material Classes—See ANSI/AWS A9.1-92 for arc welds, Guide E 1308 for polymers, Guide E 1309 for composite material, and Guide E 1471 for fibers, fillers, and core materials. ASTM Committee E49 is developing guides for other material classes.
