- Executive summary:
The density of L-TEE was determined in accordance with EU Method A.3 (Relative Density) by using a gas comparison pycnometer.
The relative density of L-TEE was established from 5 determinations of density. The relative density was determined to be 1.2223 at 20°C with a standard deviation of 0.0025.
Reference
The relative density of L-TEE was established from 5 determinations of density. The mens density was determined to be 1.2223 at 20°C with a standard deviation of 0.0025.This is equivalent to a relative density of 1.2223
