焊接及相关工艺的健康与安全 用于弧焊工艺的透明焊接帘、条和屏

[中文适用范围]： 本文件规定了在进行弧焊的工作场所使用的透明焊接帘、条和屏的安全要求。 它们旨在为处于弧焊工艺附近但不参与焊接本身的工人提供针对有害水平的光辐射和飞溅的保护。 它们的目的是减少电弧带来的不适眩光，同时也提供足够的透光率，以允许看到后面的工作空间。 透明焊接幕也可用于其他应用，只要紫外线和蓝光发射少于电弧焊，并且透射红外辐照度低于适用的暴露限制。 它们设计为在距电弧至少 1 m 的距离处使用。 本文件中指定的焊接帘、条和筛网不能替代焊接过滤器。 为了有意观察焊接电弧，可使用其他保护措施，请参阅 ISO 16321-1 和本文件不适用于 ISO 19818-1 适用的激光辐射防护。 [外文原描述]： This document specifies safety requirements for transparent welding curtains, strips and screens to be used in workplaces where arc welding is taking place. They are intended to provide protection against harmful levels of optical radiation and spatter for workers who are in the vicinity of arc welding processes but not involved in the welding itself. They are intended to reduce the discomfort glare from the arc but also allow sufficient luminous transmittance to permit a view into the workspace behind. The transparent welding curtains can also be used in other applications as long as the UV- and blue-light emissions are less than in arc welding and the transmitted infrared irradiance is below applicable exposure limits. They are designed to be used at a distance from the arc of at least 1 m. Welding curtains, strips and screens specified in this document are not intended to replace welding filters. For intentional viewing of welding arcs, other means of protection are used, see ISO 16321-1 and ISO 16321-2. This document is not applicable to protection against laser radiation, for which ISO 19818-1 applies.
