1.1本规程描述了设备控制等级（ECC）、设备控制等级（ECL）及其关系。 1.2本惯例适用于所有设备控股实体。 1.3本规程涵盖归类为设备的财产。术语E 2135中定义的设备 是指履行任务所需的非消耗性有形动产或对履行义务有用的非消耗性有形动产。 1.4本惯例可适用于单个设备项目、设备分组或实体设备的全部或子集。 1.5根据惯例E 2279的规定 ，该实践阐明并实现了对设备的有效控制和跟踪。 1.6 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本实践建立了一种标准的设备控制方法，以帮助需求确定和沟通，最终目标是发布安全、可靠、成本效益高、风险适当的控制和跟踪方法。 ECC根据设备的控制和跟踪要求为设备提供标准等级。 ECL为现有设备控制实践提供了标准名称和定义。 ECM将设备控制等级与设备控制等级相关联，为确定各类设备的安全、可靠、风险适当和经济有效的控制和跟踪提供了基线。 这种做法鼓励对设备的控制和跟踪进行全面的理解和沟通，并使对设备感兴趣的各方能够进行有意义的讨论。 本实践旨在促进和实现与这些术语和概念相关或基于这些术语和概念的其他标准实践。

1.1 This practice describes equipment control classes (ECCs), equipment control levels (ECLs), and their relationships. 1.2 This practice is intended to be applicable and appropriate for all equipment-holding entities. 1.3 This practice covers property categorized as equipment. Equipment as defined in Terminology E 2135 is non-expendable, tangible moveable property needed for the performance of a task or useful in effecting an obligation. 1.4 This practice can be applied to an individual item of equipment, to groupings of equipment, or to all or a subset of an entity's equipment. 1.5 In accordance with the provisions of Practice E 2279 , this practice clarifies and enables effective and efficient control and tracking of equipment. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This practice establishes a standard equipment control methodology to aid in requirements determination and communication with the end goal of the promulgation of safe, secure, cost effective, and risk appropriate control and tracking methodologies. The ECCs provide standard classes for equipment based on control and tracking requirements for the equipment. The ECLs provide standard names and definitions for existing equipment control practices. The ECM relates the equipment control classes to the equipment control levels, providing a baseline for determination of safe, secure, risk appropriate, and cost effective control and tracking of various classes of equipment. This practice encourages an inclusive understanding and communication of the control and tracking of equipment and enables meaningful discussion between parties with interest in the equipment. This practice is intended to foster and enable additional standard practices related to or based on these terms and concepts.
