ISO 9241-304:2008提供了使用用户性能测试方法（与ISO 9241-305中给出的光学测试方法相反）评估显示技术视觉工效学的指南。它的使用将有助于确保，对于给定的使用环境，显示器满足最低视觉工效学要求。它只涵盖视觉属性，不涉及包含视觉显示的整个产品的人体工程学或可用性。 ISO 9241-304:2008的主要用户将是采购显示器或需要在产品开发期间测量显示器性能的人。其应用假定有行为科学背景。

ISO 9241-304:2008 provides guidance for assessing the visual ergonomics of display technologies with user performance test methods (as opposed to the optical test methods given in ISO 9241-305). Its use will help to ensure that, for a given context of use, a display meets minimum visual ergonomics requirements. It covers only visual attributes and does not address the ergonomics or usability of the whole product that houses a visual display. The main users of ISO 9241-304:2008 will be those who procure displays or who need to measure display performance during product development. Its application assumes a background in behavioural science.
