ADR 2027 Table A changes, Class 5.2, organic peroxides

Class 5.2 is the most uniform set in the amendments. Ten changes across ten UN numbers, one each, all of them in column 18, all of them insertions. No organic peroxide entry gains more than a single provision and none loses one. The provision is CV29 in every case, and the entries run without a gap from UN 3111 to UN 3120, every organic peroxide type B through F, liquid and solid, under temperature control.

This page carries only the Table A changes affecting organic peroxides, which are thermally unstable and often temperature controlled. 10 individual changes across 10 UN numbers. The amendments are adopted but do not enter into force until 1 January 2027, and ADR 2025 remains usable until 30 June 2027.

The most changed column in this class is column 18, with 10 of the 10 changes.
