EC number: 227-873-2
CAS number: 6018-92-4
self ignition temperature: 263 °Cnot self heating according to UN.4
The self ignition of Nickel hydrogencitrate was tested according to the
EU method A.16 using a cube with an edge length of 20 mm and heating up
from room temperature until the self ignition temperature was reached. A
very sharp increase in the temperature of the test item was observed at
an oven temperature of 263 °C, so this value could be stated as the
For CLP-classification as self-heating substance a test according
to the guideline UN.4 was performed. No increase of the temperature in
the test item of 60 °C above the oven temperature was observed by using
a cube with an edge length of 100 mm at a temperature of 140 °C and an
exposure period of 24 h. In addition, no signs of ignition were
detectable . Therefore, no other experiments were necessary and the test
item Nickel hydrogencitrate should be classified as no self-heating
