Additional information

Read Across Statement

Fatty acids, vegetable-oil, Me esters (EINECS 273-606-8) is a typical Biodiesel product and is produced and specified according to DIN EN 14214. The DIN EN 14214 specifies all relevant physchem data. Not meeting these parameters the product cannot be placed to the market. Based on the raw material source the product can be named differently. The product used for this test, Fatty acids C16-C18 and C18-unsatd., Me esters (EINECS 267-015-4), is also a Biodiesel and fulfills the DIN EN 14214.

The auto flammability is not a standard endpoint of the DIN EN 14214. Therefore the test was performed with EC 267-015-4 and read across to EC 273 -606 -8.

The ignition delay observed at this temperature was 60 seconds and a Temperature increase at middle of the flask was 14°C. T
