1.  The classification of a mixture shall not be affected where the evaluation of the information indicates any of the following:
(a) that the substances in the mixture react slowly with atmospheric gases, in particular oxygen, carbon dioxide, water vapour, to form different substances at low concentration;
(b) that the substances in the mixture react very slowly with other substances in the mixture to form different substances at low concentration;
(c) that the substances in the mixture may self-polymerise to form oligomers or polymers, at low concentration.
2.  A mixture need not be classified for explosive, oxidising, or flammable properties as referred to in Part 2 of Annex I provided that any of the following requirements are met:
(a) none of the substances in the mixture possesses any of those properties and, on the basis of the information available to the supplier, the mixture is unlikely to present hazards of this kind;
(b) in the event of a change in the composition of a mixture, scientific evidence indicates that an evaluation of the information on the mixture will not lead to a change in classification.
