眼面防护 第4部分：生物危害防护

[中文适用范围]： 本文件规定了轻型护目设备的最低要求，旨在保护眼睛或眼睛及面部免受生物危害，如人类或其他动物体液中可能沉积在面部或眼睛上的致病性微生物。注1：典型使用场景包括医疗、零售和运输领域。本文件对一次性（可丢弃）和可重复使用（可消毒）的产品或组件均提出了要求。本文件适用于所有无焦（平光）和配镜护目设备及其组件。本文件不涵盖用于防护气溶胶的呼吸设备，此类设备可与这些护目设备配合使用，且应遵循其他相关标准。本文件不适用于以下情况：— 用于防护特定危害（如机械危害、有害的人工光学辐射、粉尘、熔融金属、热、火焰、高温固体、有害气体和蒸气）的护目设备（参考ISO 16321-1至ISO 16321-3），— 专门用于体育活动的护目设备（参考ISO 18527系列标准），— 用于激光防护的护目设备（参考ISO 19818-1），— 用于防护气溶胶的呼吸防护设备（参考ISO/TS 16975-4）。注2：附录A中提供了有关特定选择、使用和维护的指导。注3：当眼部和面部防护装置集成在防护装备中，如头罩、全脸呼吸器、动力空气净化呼吸器（PAPR）头罩和头顶部时，本文件中有关眼部和面部防护的组件要求仍适用。 [外文原描述]： This document specifies minimum requirements for light-weight protectors designed to provide protection for the eyes or eyes and face from biological hazards, such as pathogenic micro-organisms in human or other animal bodily fluids that can deposit onto the face or eyes. NOTE 1 Typical scenarios for use include healthcare, retail and transport settings. This document specifies requirements for both single-use (disposable) and re-usable (disinfectable) products or components. This document applies to all afocal (plano) and prescription lensed protectors and their components. This document does not cover the respiratory equipment required for protection against aerosols, which can be used in conjunction with these eye protectors, and for which other standards apply. This document does not apply to — protectors intended for protection from specific hazards, e.g. mechanical hazards, harmful artificial optical radiation, dusts, molten metals, heat, flame, hot solids, harmful gases, vapours (refer to ISO 16321-1 to ISO 16321-3), — protectors specifically for sports (refer to the ISO 18527 series), — protectors for lasers (refer to ISO 19818-1), and — respiratory protection against aerosols (refer to ISO/TS 16975-4). NOTE 2 Guidance related to the specific selection, use and maintenance is provided in Annex A. NOTE 3 Where eye and face protection is incorporated in protective equipment, such as a hood, full face respirators, powered air purifying respirators (PAPR) hoods and headtops, the relevant requirements of this document apply to the components providing eye and face protection.
