 Measurement  #1  #2  #3  Average
 Density (g/cm3)  1.03  1.04  1.04  1.04
Conclusions:
The density determination was carried out using a Micromeritics model 1310 automatic pycnometer. OECD 109 test methods guidelines were followed. An amount of sample is added to completely fill a sample holder and the weight as measured by difference is recorded before placing the sample holder in the pycnometer sample chamber. The sample weight is input into the pycnometer and testing started. The automated pycnometer determines the sample volume and calculates density based on the sample weight inputted into the instrument.

Three measurements were made and the average density for RD 14156 was 1.04 g/cm3
