Average		Standard deviation		Confidence interval		Lower limit		Upper limit
Operator 1	1.071		0.00317		0.008		1.063		1.079
Operator 2	1.07		0.00472		0.012		1.058		1.082

Conclusions:

The density of the reaction product was determined according to the French Norm NF T 20-050. The result can be expressed as follows:
density = 1.070 +/- 0.001 g/cm3.

Executive summary:

The study was performed in order to determine the density of test item according to Norm NF T 20-050.

The density of test item was determined to be 1.07 g/cm3 (relative density: 1.07).

Description of key information
