Abstract
The NIOSH Paint Spray Respirator Certification test was evaluated. Included in the evaluation were an assessment of the chamber flow paint spray nozzle, chamber paint concentration, paint aerosol penetration through the respirator cartridge, and paint aerosol particle size study in the chamber. Construction diagrams and specifications were provided, and a new paint and solvent mixture was employed. The paint concentration in the chamber was found to vary significantly, while the flows in the test region of the chamber were low, turbulent, and adequate. The particle size distribution of the paint aerosol was not easily controlled an was probably affected by the nozzle air supply pressure. Project protocol, comparison of various spray chamber dimensions, chamber flow diagrams, evaluation design, results of statistical analysis, construction of sample holder, and study of the NIOSH lacquer test are appended.
