- Executive summary:
INTRODUCTION
Hazardous physico-chemical properties of the test material have been determined. Methods employed were those specified in Commission Regulation (EC) No 440/2008 of 30 May 2008, Part A: Methods for the determination of physico-chemical properties.Method
The vapour pressure was determined using a vapour pressure balance, with measurents being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. Testing was conducted using Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008.
