Description
Summary:Methods for the controlled generation and characterization of fumes from flux coated rod and metal inert gas welding processes are given. The design of equipment for the exposure of experimental animals to atmospheres containing known uniform concentrations of fume materials for more than 5 h is described. Physical characteristics of particulates in the fume which are related to inhalation toxicology, such as surface topography, solubility, and particle size have been established.
