焊接和相关工艺的健康和安全.烟和气体取样的实验室法.第3部分:电弧焊时臭氧排放率的测定

[中文适用范围]： 本部分ISO 15011定义了使用集气罩技术测量电弧焊过程中臭氧排放率的实验室方法。该方法主要针对使用气体保护电弧焊工艺测量臭氧排放率，但也可用于其他工艺，例如自保护药芯电弧焊，前提是焊接可以在集气罩下自动进行。该方法可用于评估焊丝、焊接参数、工艺、保护气体、试件成分和试件表面状况对排放率的影响。 [外文原描述]： ISO 15011-3:2009 defines a laboratory method for measuring the emission rate of ozone during arc welding, using a hood technique. The method is directed primarily at measuring ozone emission rate when using gas-shielded arc welding processes, but it can also be employed with other processes, e.g. self-shielded flux-cored arc welding, provided that welding can be performed automatically under the hood.
