National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Comparison of Respirator Particulate Filter Test Methods.

PB83159335

Publication Date	1980
Personal Author	Reed, L. D.; Smith, D. L.; Mollman, T. C.; Frockt, I. J.
Page Count	29
Abstract	Four respirator particulate filters were evaluated. Penetration of monodisperse-dioctyl-phthalate (117817) (MDOP), silica (7631869), dust, lead (7439921) fumes, and sodium-chloride (7647145) (NaCl) aerosol was measured by light scattering and propane flame photometry. The effects of humidity and charge on NaCl penetration was also studied. The authors conclude detection might improve with a more sophisticated system using hydrogen flame, instead of propane flame photometry, and more refined electronic equipment.
