眼睛和面部保护.太阳镜和相关眼镜.第3部分:跑步、骑自行车和类似活动生活方式用太阳镜

[中文适用范围]： 本文件适用于所有名义上的无焦点（平光动力）太阳镜，以防止跑步、骑自行车和进行类似的积极生活方式娱乐活动时的环境因素，例如太阳辐射、风、灰尘和雨水，但不适用于以下情况下的竞技体育活动：需要增强的抗冲击性。 该文件规定了额外的材料、设计、性能和标记要求。 ISO 12312-1 中给出了其他适用的要求。 这种类型的太阳镜旨在减少事故中佩戴者的二次危险，而不是提供大量的冲击保护，而这在眼镜形式中可能是困难的。 本文件不适用于： a) 用于防护人造光源辐射的眼镜，例如日光浴室中使用的眼镜； b) 用于特定运动的护目镜，例如滑雪护目镜或其他类型——参见 ISO 18527（所有部分）； c) 用于包括使用球、球棒、球棒、球拍或其他工具的运动的护目镜； d) 医学上规定用于减弱太阳辐射的太阳镜； e) 用于直接观测太阳的产品，例如用于观看日偏食或日环食，ISO 12312-2 适用于此； f) 用于职业眼睛保护的产品——例如，参见 ISO 16321（所有部分）。 [外文原描述]： This document is applicable to all nominally afocal (plano power) sunglasses for protection against environmental elements, such as solar radiation, wind, dust and rain when running, cycling and following similar active lifestyle recreational activities but not intended for competitive sporting activities where enhanced impact resistance is required. The document specifies additional material, design, performance and marking requirements. The other applicable requirements are given in ISO 12312‑1. This type of sunglass is designed to reduce secondary hazards to the wearer in an accident rather than to provide high amounts of impact protection which may be difficult in a spectacle format. This document is not applicable to: a) eyewear for protection against radiation from artificial light sources, such as those used in solaria; b) eye protectors intended for specific sports, e.g. ski goggles or other types – see ISO18527 (all parts); c) eye protectors for sports that include the use of a ball, stick, bat, racquet or other implement; d) sunglasses that have been medically prescribed for attenuating solar radiation; e) products intended for direct observation of the sun, such as for viewing a partial or annular solar eclipse, for which ISO12312-2 applies; f) products intended for occupational eye protection – for example, see ISO16321 (all parts).
