Materials and methods

Test guideline
Qualifier:
according to
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Principles of method if other than guideline:
The test was carried out in accordance with Test A15, refernce 6.1, using IEC 79-4, "Method of Test for Ignition Temperature", but
using 5°C increments rather than teh specified 2°C increments.

a 200ml Erlenmeyer flask of borosilicate glass is enclosed within a cylindrical furnace capable of maintaining teh surfaces of the flask at a uniform, constant temperature.
GLP compliance:
yes (incl. certificate)

Any other information on results incl. tables

Sample preparation: The test substance was warmed to 65°C to make it more mobile to permit the use of a syringe (without the needle) for injecting the material into the test flask.

The results shown in teh Table below represent the lowest ignition temperatures obtained from the five test series.
