Centro de Documentacion de Fundación MAPFRE - Comparison of alpha-quartz standard sikron F600 (HSE A9950) with the nist respirable alpha-quartz standard SRM 1878 for bulk and on-filter analysis

Notas: Sumario: A batch of alpha-quartz designated Sikron F600, and labelled A9950 by this laboratory, has been used as the calibration standard for the analysis of alpha-quartz both in bulk samples and in airborne dust collected on-filter since 1980. The results obtained on comparing this standard with SRM 1878, a respirable alpha-quartz standard for X-ray diffraction measurement certified 95.5-1.1% crystalline alpha-quartz, available from the National Institute of Standards and Technology U.S.A., are presented in this reportRegistros relacionados: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 2, April 1993 ; p. 167-179Materia / lugar / evento: Health and Safety Executive Higiene industrial Contaminantes químicos Cuarzo Métodos de análisis Normas Sikron F600 SRM 1878 Otros autores: Nagar, N.
