Centro de Documentacion de Fundación MAPFRE - NIOSH Method 7402-asbestos fibers (revision #1) : low-temperature ashing of filter samples

Notes: Sumario: As a result of experiments involving scanning electron micrograph (SEM) analysis of low-temperature ashed filters Method 7402 was revised to clarify these issues. Because Method 7402 is used to provide the fraction of optically visible asbestos fibers in a sample, the previously recommended low-temperature ashing step may cause an overestimate of the asbestos fractionRelated records: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 51, nº 11, November 1990 ; [2] p.Materia / lugar / evento: Higiene industrial Contaminantes químicos Amianto Fibras Muestreos Filtros Métodos de análisis Control de contaminantes Método N.I.O.S.H.
