The following word and term shall, for the purposes of this chapter and as used elsewhere in this code, have the meanings shown herein.
ORGANIC PEROXIDE. An organic compound that contains the bivalent -O-O- structure and which may be considered to be a structural derivative of hydrogen peroxide where one or both of the hydrogen atoms have been replaced by an organic radical. Organic peroxides can present an explosion hazard (detonation or deflagration) or they can be shock sensitive. They can also decompose into various unstable compounds over an extended period of time.
Class I. Describes those formulations that are capable of deflagration but not detonation.
Class II. Describes those formulations that burn very rapidly and that pose a moderate reactivity hazard.
Class III. Describes those formulations that burn rapidly and that pose a moderate reactivity hazard.
Class IV. Describes those formulations that burn in the same manner as ordinary combustibles and that pose a minimal reactivity hazard.
Class V. Describes those formulations that burn with less intensity than ordinary combustibles or do not sustain combustion and that pose no reactivity hazard.
Unclassified detonable. Organic peroxides that are capable of detonation. These peroxides pose an extremely high-explosion hazard through rapid explosive decomposition.
