1.1 本实践描述了工具的区别、识别和分类标准，既独特又更一般。物理标记应允许确定以下一项或多项:零件号、序列号、所有权、版本或符号，或其组合。 1.2 将描述构成工具系列的独特子类别的定义。这些子类别有助于区分用于标识、控制和记录保存的工具类别。 1.3 该做法旨在适用于持有工具的所有实体，无论其所有权或收购方法如何。本实践进一步提供了详细信息，以提供通用术语、识别和跟踪独特工具的灵活性。 1.4 本规程未涵盖但定义的项目包括但不限于:消耗品、特殊测试设备（STE）、工厂设备、通用或特殊机械设备以及消耗性工具。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 工具的分类和识别具有广泛的优势，有助于保持不间断、高效和连贯的业务实践。这些包括但不限于识别操作关键项、提高工具利用率，以及帮助分配资源和管理生产。 4.2 模具有着广泛的应用。该实践旨在澄清不同工具组之间的差异，并为跨行业的标准通信提供标识符号。 4.3 无论所有权或收购方法、工具类型、其内部分配和使用的细节或未来可能的要求如何，本实践中反映的独特工具的识别将提供对可用性的包容性和比较性见解。 这种识别组合使车间能够轻松识别制造过程中所需的工具系列，并轻松召回正确的工具以供使用。

1.1 This practice describes the differentiation, identification, and categorization criteria for tooling, both unique and more general in nature. The physical markings should allow for one or more of the following to be ascertained: part number, serial number, ownership, revision, or symbology, or combination thereof. 1.2 Definitions for the unique subcategories that make up the tooling family will be described. These subcategories help to differentiate tooling categories for use in identification, control, and record keeping. 1.3 This practice is intended to be applicable and appropriate for all entities that hold tooling regardless of ownership or acquisition methodology. This practice further provides the detailed information to provide the flexibility of common nomenclature, identification, and tracking of unique tooling. 1.4 Items not covered but defined by this practice include, but are not limited to: consumable property, special test equipment (STE), plant equipment, general or special machinery equipment, and expendable tools. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The categorization and identification of tooling has a wide range of advantages to assist in maintaining an uninterrupted, productive, and cohesive business practice. These include, but are not limited to, identifying operation critical items, increasing tool utilization, and helping to allocate resources and manage production. 4.2 Tooling has a wide range of applications. This practice is intended to clarify the differences between the different groups of tooling and provide identification symbolism for standard communication across industries. 4.3 The identification of unique tooling reflected in this practice will provide inclusive and comparative insight into the availability regardless of ownership or acquisition methodology, tooling type, specifics of its internal assignment and use, or possible future requirements. This identification combination allows the shop floor to identify readily the family of tools required in the manufacturing process and recall readily the correct tool for usage.
