1.1本实践建立了一个定量过程，即资产优先级指数（API），用于在获取、利用和处置中对资产资源进行优先级排序，以向管理者提供一种基于预定义标准对资产资源进行优先级排序的方法。 1.2 API具有广泛的应用，包括但不限于用作资本投资策略、延迟维护方法、安全设计和分析、业务/风险分析的连续性和处置决策的基础。 1.3 API模型旨在适用于持有指定为资本资产的设备的实体。 1.4除了本惯例中定义的可移动和耐用资产的适用性外，本方法可全部或部分有效应用于无形财产、不动产和物资。 本规程提供了执行一个或多个特定操作的说明。本文件不能取代教育或经验，应与专业判断一起使用。并非本惯例的所有方面都适用于所有情况。本ASTM标准既不代表或取代必须根据其判断特定专业服务是否充分的谨慎标准，也不应在不考虑许多独特方面的情况下应用本文件。标题中的“标准”一词仅表示该文件已通过ASTM国际共识程序获得批准。 ====意义和用途====== API是一种指标，用于传达设备在任务关键性、安全性或对业务实体重要的其他措施方面的相对重要性。它提供了一种基于组织定义的判断/重要性因素对资产进行排序的方法，创建信息以证明投资、安全策略和处置计划的有力论据。 API还为确定和记录资产组合和业务目标之间的运营关系提供了定量基础资本投资策略、延迟维护方法、安全设计和分析、业务/风险分析的连续性和处置决策。 它使管理层能够识别关键资产并适当分配资源，因此应成为设备管理的一个完整过程。

1.1 This practice establishes a quantitative process, an asset priority index (API), for prioritizing asset resources in acquisition, utilization, and disposition to provide managers with a method to prioritize asset resources based on predefined criteria. 1.2 The API has a wide range of applications including, but not limited to, use as a basis for capital investment strategies, deferred maintenance approaches, security design and analyses, continuity of business/risk analyses, and disposition decisions. 1.3 The API model is designed to be applicable and appropriate for entities holding equipment designated as capital assets. 1.4 In addition to the applicability of moveable and durable assets as defined in this practice, this methodology may in whole or in part be effectively applied to intangible property, real property, and materiel. This practice offers instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is neither intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a projects many unique aspects. The word "Standard" in the title means only that the document has been approved through the ASTM International consensus process. ====== Significance And Use ====== The API is a metric used to communicate the relative importance of equipment in terms of mission criticality, security, or other measures important to the business entity. It offers a method for ranking assets based on judgment/importance factors defined by the organization, creating information to justify compelling arguments for investment, security strategies, and disposition plans. API also provides a quantitative basis for determining and documenting operational relationships between an asset portfolio and business objectives capital investment strategies, deferred maintenance approaches, security design and analyses, continuity of business/risk analyses, and disposition decisions. It enables management to identify critical assets and allocate resources appropriately and should therefore be an integral process in equipment management.
