4.1 Classification of organic peroxides

Organic peroxides according to their degree of danger divided into A ~ G type seven types, see GB 19521.12. Organic peroxide packet

Mounted only applies to B ~ F type wherein an organic peroxide.

a) A type organic peroxides, organic peroxide formulations, such as to detonate or deflagrate rapidly within a transport packaging container, particularly

According to GB 21178 determination, determined to A. It should be prohibited into the container of the present standard transportation regulations.

b) B-type organic peroxides, organic peroxide formulation having explosive properties, as neither transport in the packaging container detonating

Nor deflagrates rapidly, but may undergo a thermal explosion in that packaging containers, it should be labeled "EXPLOSIVE" subsidiary risk label. This organic

Number of peroxide in a container up to 25kg, but in order to exclude rapid deflagration or detonation in a packaging container is required

The highest number of the lower restricted number of persons except for specific determination based on GB 21178, it is determined that B.

c) C-type organic peroxides, organic peroxide formulation having explosive properties, such as transport containers (up to

Within 50kg) can not detonate or deflagrate rapidly or undergo a thermal explosion, not "EXPLOSIVE" subsidiary risk label transport, according to the specific

According to GB 21178 determination, determined to C.

d) D-type organic peroxides, organic peroxide formulation, if in laboratory testing.

1) partially detonation, deflagration not quickly, does not show any dramatic effect when heated under confinement;

2) does not detonate, a slow deflagration, do not show any dramatic effect when heated under confinement;

3) does not detonate or deflagrate showing a medium effect when heated in a closed condition;

Acceptable weight of not more than 50kg installed in a packaging container transport, particularly a determination based on GB 21178, it is determined that D.

e) E-type organic peroxides, organic peroxide formulation, as in laboratory testing, neither did not detonate explosive also did not

Burning, displayed only a weak or no effect when heated in a closed condition, does not exceed the acceptable fitted 400kg/450L packet

Container transport means, particularly based on a determination GB 21178, it is determined that E.

f) F type organic peroxides, organic peroxide formulation, in laboratory testing, the detonation of both not empty state

Never deflagration, show only weak or no effect when heated in a closed condition, and little or no explosive, may be considered

IBCs or tanks for the transport may be considered for IBC or transportation tanks, particularly based on a determination GB 21178, sentence

As F.

g) G organic peroxides, organic peroxide formulation, in laboratory testing, the detonation of both not empty state

Nor deflagrates, showed no effects and no explosive power shall be exempt from classified 5.2 when heated under confinement conditions

The formulation is thermally stable (self accelerating decomposition of the packaging container 50kg temperature of 60 °C or higher), so that the liquid formulation

Desensitized type A diluent. If the formulation is not thermally stable, with a diluent or desensitized type A other than diluents, particularly

Judged according to GB 21178, judged G.
