Key value for chemical safety assessment

Additional information

The pure dried solid test item ETA Lösung 181 / TRISODIUM EDTA SOLUTION 20% indicated self-ignition at atmospheric pressure starting at a temperature of 230 °C. Due to the high onset temperature in the Grewer Oven, it can be assumed that the UN Test N.4 using the 25 mm cube sample at 140 °C is negative. The test item is not self-heating.
