ISO/IEC 29138-1:20 18本文件确定了不同用户对ICT系统的一系列用户可访问性需求，以使他们能够访问这些系统。每个用户可访问性需求可能是个人对系统的要求。不同的用户在不同的上下文中可以有不同的用户可访问性需求集。 虽然这套用户无障碍需求是为信通技术领域开发的，但这套用户无障碍需求中的许多也适用于其他领域。 本文档未提供用户无障碍需求申请和评估的要求或具体流程和方法。然而，它可以为此类要求的制定提供信息（见5.4）。 本文档不是为认证目的或监管或合同用途而设计的。 本文件中的用户无障碍需求旨在告知和鼓励负责无障碍的人员超越无障碍立法和法规的最低限度规定.

ISO/IEC 29138-1:2018 This document identifies a collection of user accessibility needs that diverse users have of ICT systems to make these systems accessible to them. Each user accessibility need might be required of a system by an individual. Different users can have different sets of user accessibility needs in different contexts.
While this set of user accessibility needs was developed for the domain of ICT, many of the user accessibility needs in this set also apply in other domains.
This document does not provide requirements or specific processes and methods for the application and evaluation of user accessibility needs. However, it could inform the development of such requirements (see 5.4).
This document is not designed for certification purposes or regulatory or contractual use.
The user accessibility needs in this document are intended to inform and encourage those responsible for accessibility to go beyond the minimum provisions of accessibility legislation and regulations.
