Section: ArticlesTitle: "Worst case" aerosol testing parameters. II : efficiency dependence of commercial respirator filters on humidity pretreatment / Ernest S. Moyer and Gregory A. StevensAuthor: Moyer, Ernest S.Notes: Sumario: Previous studies have shown that relative humidity has a degrading effect on the performance of commercially available particulate air-purifying respirator filters. This study was done to evaluate the time-dependent effects of relative humidity pretreatment and the reduction of charge on filter penetration against a most penetrating "worst case" aerosol challengeRelated records: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 50, nº 5, May 1989 ; p. 265-270Materia / lugar / evento: Higiene industrialContaminación atmosféricaContaminantes químicosAerosolesControl de la contaminaciónMétodos de controlFiltrosHumedadOtros autores: Stevens, Gregory A.
