Executive summary:

Introduction

Hazardous physico-chemical properties of the test item have been determined.Methods employed are designed to be compatible with 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 withasurents being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. Testing was conducted using a procedure designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Results

No apparent change in the appearance of the test item was noted over the duration of the test.

The vapour pressure of the test item has been determined to be 9.0E-03 Pa at 25°C.

Description of key information

The vapour pressure of the test item has been determined to be 9.0E-03 Pa at 25 °C.
