Conclusions:

A gas comparison stereopycnometer was used for the determination of the density and relative density of Lowinox® 22IB46.
The density of the test item at 20°C was 1.16 g/cm3 (1.16 x 103 kg/m3).
The relative density was 1.16.

Executive summary:

The purpose of the study was to determine the physico-chemical properties for Lowinox® 22IB46.

 

The density (ρ) and relative density (D²⁰₄) of the test item were determined using a gas comparison stereopycnometer. With this method the volume of the test item is measured in helium gas in a calibrated cylinder. Study performed in accordance with the following guidelines:
