IEC 60300-3-14:20 24介绍了可支持性（和支持）的可靠性属性以及与可靠性、可维护性和可用性相关可靠性属性的关系。 该文档可在项目生命周期中的任何时候用于指导可支持性和支持活动的规划和实施，重点是实现性能、成本和风险的预期平衡。所有活动都可以根据物品的性质及其使用条件进行定制。 就如何在新设计的物品、可用于商业采购的现有物品或在其使用寿命期间的物品的任何生命周期阶段应用可支持性和支持活动提供了指导。 本文件通过正式管理与创建、操作、维护和翻新项目以实现其既定目的的活动的管理和交付相关的风险来考虑生命周期的影响。本文档描述了: -可支持性和支持的性质； -可支持性和支持在实现项目寿命期间的价值方面的作用； -与可支持性和支持相关联的权衡，以在物品的寿命期间实现成本、性能和风险的期望平衡； -必须使组织的结构与其目标保持一致，最终目的是提高效率和效力，以便提供所需的可支助性和支助。 这第二版取消并取代了2004年出版的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)与IEC TC 56编制的其他堆芯可靠性标准的一致性； b)扩展可支持性并支持可靠性方面的原则和活动。

IEC 60300-3-14:2024 introduces the dependability attribute of supportability (and support) and the relationship with related dependability attributes of reliability, maintainability and availability.
This document can be used at any time during an item’s life to guide the planning and implementing of supportability and support activities focused on achieving an intended balance of performance, cost and risk. All activities can be tailored to the nature of the item and its conditions of use.
Guidance is offered on how supportability and support activities can be applied at any life cycle stage for newly designed items, existing items available for commercial procurement, or for items during their operational life.
This document considers the life cycle implications by formally managing risks associated with the management and delivery of activities to create, operate, maintain and refurbish an item to achieve its stated purpose.
This document describes the:
- nature of supportability and support;
- role of supportability and support in achieving item value over its life;
- trade-offs associated with supportability and support to achieve desired balance of cost, performance and risk during the life of an item;
- importance of aligning the structure of an organization with its objectives, with the ultimate aim of improving efficiency and effectiveness in order to deliver the required supportability and support.
This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) consistency with the other core dependability standards prepared by IEC TC 56;
b) expansion of supportability and support principles and activities in dependability.
