Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
Due to the fact that under normal conditions, ethanedinitrile is a gaseous substance and therefore vapour pressure exceeds standard atmospheric pressure, none of the methods in Annex A 4, to Regulation No 440/2008 is suitable, as these methods are limited by the vapour pressure to 10 5 Pa.
GLP compliance:
no
Type of method:
static method
