Materials and methods

Test guideline
Qualifier:
no guideline required
Principles of method if other than guideline:
According to column 2 of REACH Annex VII study does not need to be conducted if substance is a gas. In this case, an estimation based on calculation shall be made from its molecular weight and the Ideal Gas Laws.
Based on document nr EH/228/10 the density calculated from molecular weight and the Ideal Gas Laws is 0,936 kg/m3.
GLP compliance:
no
Type of method:
other: estimated by calculation
