Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study performed in accordance with GLP to a recognised standard
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC method MT 59 “Sieve Analysis”, CIPAC Handbook Volume F, Physico-Chemical Methods for Technical and Formulated Pesticides, 1995.
- GLP compliance:
- yes
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- Key result
- Percentile:
- other: not measured
- Remarks on result:
- other: 84.3% volume of the test substance was found to be > 2000 μm. 0.9% volume of the test substance was found to be < 100 um.
- Conclusions:
- The particle size distribution of Formaldehyde, oligomeric reaction products with acetone and diphenylamine was determined by sieving. The results are given in the table. In the receiver pan (i.e. the fraction < 100 μm), 0.9% test item was collected.
- Executive summary:
The aim of the test was to determine the particle size distribution of the formaldehyde, oligomeric reaction products with acetone and diphenylamine using sieve analysis (dry sieving). Study was conducted according test guideline:
CIPAC method MT 59 “Sieve Analysis”, CIPAC Handbook Volume F, Physico-Chemical Methods for
Technical and Formulated Pesticides, 1995.
In conclusion 84.3% volume of the test substance was found to be > 2000 μm
