Science - Chemistry; Chem Sci/Eng / MSDS | | English term or phrase: Size-Weighted Respirable Fraction | | DIN 33898, 1.9.2010, SWeRF (Size Weighted Respirable Fraction) and SWeRFcs (Size Weighted Respirable Fraction of Crystalline Silica). |
| | | vdechovatelná frakce vážená rozměrem (částic) - SWeRF | Explanation:
Jedná se o parametr, který vyjadřiuje pravděpodobnost vdechnutí částic podle rozdělení jejich velikostí.
The difference is that the particle of 1 μm has,
according to European standard EN 481, a probability of 97.1 % of reaching the alveoli, as compared to only 1.3 % for the particle of 10 μm.
By applying a greater weighting to the finer particles, it is possible to express the difference in potential health hazard. The SWeRF of a particulate material is calculated by combining the amount of particles of a certain size, with their probability of reaching the alveoli when inhaled. |
