Results

Table 1. Testing of impact sensitivity

                                                                                                                                

Mass of a drop weight [kg]	Height of falling of the drop weigh [cm]	Number of
		explosions	trials
10	40	0	6

 

From table 1. it can be seen thatin the test with the dropped weight of 10kg falling from the height of 40cm no explosion transformation of chelate Fe(III)IDHA has been recognized.

Table 2.Testing of friction sensitivity

                                                                                                                                

Stimulus [N]	Number of
	explosions	trials
360	0	6

From table 2. it can be seen thatin the test with the loading device No 9 attached to the lever on notch No 6 (stimulus 360 N) no explosion transformation of chelate Fe(III)IDHA has been recognized.

Table 3.Testing of thermal sensitivity

                                                                                                                             

Test No.	Diameter of the hole [mm]	Weigth of sample [g]	Time from beginning of heating to the end of decomposition, [s]	Confinement after test	Effect
1	6,0	31,83	154 ± 10	unchanged	O
2	2,0	31,10	210 ± 10	unchanged	O
3		30,38	139 ± 10	tube split into 2 fragments	E
4		15,14	147 ± 10	unchanged	O
5	1,0	32,41	85 ± 10	tube split into 2 fragments	E

From table 3.and presented above discussion, it can be seen thatin the test with the orifice plate diameter equal or bigger than 1.0mm no explosion transformation of chelate Fe(III)IDHA has been recognized.

Interpretation of results:

non explosive

Remarks:

Migrated information

Conclusions:

Chelate Fe(III)IDHA does not present a danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock or friction (sensitivity to mechanical stimuli).

Executive summary:

Determined sensitivity ofchelate Fe(III)IDHA to impact is over40J, to friction is over 360 N, and thermal sesnitivity, expressed by limiting diameter is less. According to Appendix to Regulation of Ministry of Health dated28.07.2003 on methods to determine the physico-chemical properties, toxicity and ecotoxicity of chemicals and preparates (Appendix to no 232 p. 2343, dated31 December 2003):

 

chelate Fe(III)IDHAdoes not presenta

danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock or friction (sensitivity to mechanical stimuli).

Description of key information

Chelate Fe(III)IDHA does not present a danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock or friction (sensitivity to mechanical stimuli).

Key value for chemical safety assessment

Explosiveness:
