Activated Carbon - Low Density Skeleton

Substance description: A porous, amorphous, high surface area adsorbent material composed of largely elemental carbon, with a low skeletal density.

(Activated carbon with a low density skeleton is produced by activation with chemical activation agents such as phosphoric acid, of various raw materials such as wood and synthetic sources.)

Analytical identity:

Classification: Either one of the following classifications may apply:

- not classified

- classified as Self-heating (corresponding to transport class 4.2)

The producer/importer shall determine for his products which of these two possibilities apply, by testing the material and considering the packaging size.

If your substance is to be classified as self-heating category 2 needs to be determined based on test results of your particular substances as placed on the market. Figure 2.11.1 of the ECHA guidance on the application of the CLP criteria gives a flow scheme to determine if the substance needs to be classified as Self Heating, category 2 (http://echa.europa.eu/documents/10162/13562/clp_en.pdf).

Packaging group needs to be determined based on the test results for your substance. Figure 33.3.1.3.3.1 of UNECE document on the transport of dangerous goods, part III Classification procedures, test methods and criteria relating to class2, class 3, class 4, division 5.1, class 8 and class 9 provides a flow scheme to determine the packaging group for self-heating substances (http://www.unece.org/fileadmin/DAM/trans/danger/publi/manual/Rev5/English/03en_part3.pdf).
