sensitivity to shock;
effect of heating under confinement;
effect of ignition under confinement;
sensitivity to impact;
sensitivity to friction;

The following total percentage (by mass) of flammable components may be provided, unless the aerosol is classified as Aerosol category 1 because it contains more than 1 % (by mass) flammable components or has a heat of combustion of at least 20 kJ/g and is not submitted to the flammability classification procedures (see the Note in Paragraph 2.3.2.2 of Annex I to Regulation (EC) No 1272/2008);
As regards pure gas, the C i (coefficient of oxygen equivalency) as per ISO 10156 ‘Gases and gas mixtures – Determination of fire potential and oxidizing ability for the selection of cylinder valve outlets’, or as per an equivalent method, may be provided;
As regards a gas mixture, the words ‘oxidising gas Category 1 (tested as per ISO 10156 (or as per an equivalent method))’ may be indicated as regards tested mixtures, or the calculated oxidising power as per ISO 10156 or as per an equivalent method;
As regards pure gas, critical temperature may be provided.
As regards gas mixture, pseudo-critical temperature may be provided;
When the substance or mixture is classified as flammable liquid, data on the boiling point and flash point do not need to be provided under this point as that data are to be indicated in accordance with the subsection 9.1. Information on sustained combustibility may be provided.
The following information may be provided:
burning rate, or burning time as regards metal powders,
statement on whether the wetted zone has been passed;
In addition to the indication of the SADT as specified in point (j) of subsection 9.1, the following information may be provided:

Information on whether spontaneous ignition or charring of filter paper occurs may be provided.
The following information may be provided:
statement on whether spontaneous ignition occurs when poured or within five minutes thereafter, as regards solids in powder form,
statement on whether pyrophoric properties could change over time.
The following information may be provided:
statement on whether spontaneous ignition occurs and the maximum temperature rise obtained,
results of screening tests referred to in section 2.11.4.2 of Annex I to Regulation (EC) No 1272/2008, if relevant and available;
The following information may be provided:
identity of the emitted gas, if known,
statement on whether the emitted gas ignites spontaneously,
gas evolution rate;
Information on whether spontaneous ignition occurs when mixed with cellulose may be provided.
