1.1 资产优先级指数（API）建立了一个定量过程，用于在获取、利用和处置中对资产资源进行优先级排序。 1.2 除了本实践中定义的可移动和耐用资产的适用性外，该方法同样用于分析建筑物和建筑系统的投资（见实践） E1765 ). 1.3 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标准既不代表也不取代必须根据其判断给定专业服务的充分性的谨慎标准，也不应在不考虑项目的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。 1.4 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====== 5.1 API是一种指标，用于传达资产在任务关键性、安全性或对实体重要的其他措施方面的相对重要性。它为评估资产资源的优先级奠定了基础。 5.2 API提供了一种基于实体定义的判断/重要性因素对资产进行排序的方法，创建信息以确定投资、安全策略和处置计划的优先级。 5.3 API为确定和记录资产组合和实体资本投资策略、维护方法、证券设计和分析、业务/风险分析的连续性和处置决策之间的运营关系提供了定量基础。 5.4 API使实体能够识别关键资产并适当分配资源。 5.5 API模型适用于持有对实体任务有重大影响的资产的实体。

1.1 The asset priority index (API) establishes a quantitative process for prioritizing asset resources in acquisition, utilization, and disposition. 1.2 In addition to the applicability of moveable and durable assets as defined in this practice, this methodology is similarly used in the analysis of investments in buildings and building systems (see Practice E1765 ). 1.3 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 nor 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 project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM International consensus process. 1.4 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 ====== 5.1 The API is a metric used to communicate the relative importance of assets in terms of mission criticality, security, or other measures important to the entity. It establishes a basis for evaluating prioritization of asset resources. 5.2 API offers a method for ranking assets based on judgment/importance factors defined by the entity, creating information to prioritize investments, security strategies, and disposition plans. 5.3 API provides a quantitative basis for determining and documenting operational relationships between an asset portfolio and entity capital investment strategies, maintenance approaches, security design and analyses, continuity of business/risk analyses, and disposition decisions. 5.4 The API enables entities to identify critical assets and allocate resources appropriately. 5.5 The API model is designed to be applicable and appropriate for entities holding assets with a material impact on the entity’s mission.
