The study entitled "Determination of Density and Specific Gravity of PolyPerin Y" was performed according to the Guideline OECD 109 (GLP).
Density and Specific Gravity of the test item was determined by Pycnometer method at 20.0 ± 1.0 °C. Water equivalent was determined prior to determination of density of test item at test temperature. Average Density of PolyPerin Y was determined as 1.4327 g/mL and the average Specific Gravity of PolyPerin Y was determined as 1.4352 at 20.0 ± 1.0 °C.

Applicant's summary and conclusion
- Conclusions:
- Based on the results obtained from the study, it was concluded that the cumulative percentage of PolyPerin Y was 99.23% and % dust fraction through 150 μm sieve in the receiver pan including the loss during the sieving of PolyPerin Y was 93.42%.
- Executive summary:
The study “Determination of Dry Sieve Test of PolyPerin Y” was performed according to Guidelines: CIPAC MT 59. A sample of the test item was poured in the nest of the test sieves of 200 mm diameter of aperture sizes: 150, 250, 355, 425, 500, 710 μm and 850 μm respectively. The mean apparent density of the test item was found to be 0.678 g/mL. The nest of sieves along with test item was shaken for period of 45 minutes and was allowed to settle for about 2 minutes. The mass of the test item from the nest of the 850 μm to 250 μm sieves, was collected together and weighed. The mass of the test item from 150 μm sieve and in the receiver pan was also weighed. From these weights loss of dust during sieving was calculated. The % loss of dust during sieving was found within acceptance criteria (< 0.25%) for both the determinations. The mean of cumulative percentage of two samples of test item was found to be 99.23% which was not within the acceptance criteria (4.4%) and the mean % dust fraction was found to be 93.42 % of test item through 150 μm sieve in the receiver pan including the loss during the sieving was not found within the acceptance criteria (1.1%). Based on the results obtained from the study, it is concluded that the cumulative percentage of PolyPerin Y was 99.23% and % dust fraction through 150 μm sieve in the receiver pan including the loss during the sieving of PolyPerin Y was 93.42%.
