Additional information

According to Regulation (EC) No.1907/2006, Annex XI, Section 1, the testing regime may be adapted because testing does not appear scientifically necessary. Data exists on the melting point of potassium cyanide, equal to 634.5 degrees C. According to Regulation (EC) No. 440/2008, this test method on solids is intended as a preliminary screening test on self-heating properties which can lead to self-ignition. The test involves heating the solid substance to a temperature of 400 degrees C in an oven. The melting point of NaCN is higher than 400 degrees C, with no indication that self-heating at 400 degrees C occurs. This test is not scientifically justified.
