Key result
Percentile:
other: 6.76 %
Mean:
< 100 µm
Remarks on result:
other: The percentage of test item having an inhalable particle size of less than 100 μm was determined to be 6.76%. The test item has been considered to be essentially non-inhalable.
Remarks on result:
not measured/tested
Conclusions:
The percentage of test item having an inhalable particle size of less than 100 μm was determined to be 6.76%. The test item has been considered to be essentially non-inhalable.
Executive summary:

The general physico-chemical properties of Formaldehyde, reaction products with aniline, 4,4'-methylenebis[phenol] have been determined.

Particle Size Distribution. The proportion of test item having an inhalable particle size of less than 100 μm was determined by a sieve method to be 6.76%, particle size data was acquired, using a procedure designed to be compatible with the European Commission Technical Guidance Document EUR 20268 Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of Chemical Substances (2002)
