Y11 Waste carry residues arising from refining, distillation and any pyrolitic treatment.
Y12 Wastes from production, formulation and use of inks, dyes, pigments, paints, lacquers, varnish.
Y13 Wastes from production, formulation and use of resins, latex, plasticizers, glues/adhesives.
Y14 Waste chemical substances arising from research and development or teaching activities which are note identified and/or are new and whose effects on man and/or the environment are not known.
Y15 Wastes of an explosive nature.

List of hazardous characteristics:

H1 Explosive:

An explosive substance or waste is a solid or liquid substance or waste (or mixture of substances and wastes) which is in itself capable by chemical reaction of producting gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.

H3 Flammable liquids:

The word "flammable" has the same meaning as "inflammable". Flammable liquids are liquids, or mixtures of liquids, or liquids containing solids in solution or suspension (for example paints, varnishes, lacquers, etc., but not including substances or wastes otherwise classified on account of their dangerous characteristics) which give off a flammable vapour at temperatures of not more than 60,5 °C, closed-cup test, or not more than 65,6 °C open-cup test.

H4.1 Flammable solids:

Solids, or waste solids, other than those classed as explosives, which under conditions encountered in transport are readily combustible, or may cause or contribute to fire through friction.

H4.2 Substances or wastes liable to spontaneous combustion:

Substances or wastes which are liable to spontaneous heating under normal conditions encountered in transport, or to heating up on contact with airm and being then liable to catch fire.

H4.3 Substances of wastes which, in contact with water emit flammable gases:

Substances or wastes which, by interaction with water, are liable to become spontaneous by flammable or to give off flammable gases in dangerous quantities.

H5.1 Oxidizing:

Substances or wastes which, while in theme-selves not necessary combustible, may, generally by yielding oxygen cause, or contribute to, the combustion of other materials.

H5.2 Organic peroxides:

Organic substances or wastes which contain the bivalent-O-O-structure are thermally unstable substances which may undergo exothermic self-accelerating decomposition.

H6.1 Poisonous (Acute):

Substances or wastes liable either to cause death or serious injury or to harm human health if swallowed or inhaled or by skin contact.

H6.2 Infection substances:

Substances or wastes containing viable micro organisms or their toxins which are known or suspected to cause disease in animals or humans.

H8 Corrosives:

Substances or wastes which, by chemical action, will cause severe damage when in contact with living tissue, or, in the case of leakage, will materially damage, or even destroy, other goods or the means of transport; they may also cause other hazards.

H10 Liberation of toxic gases in contact with air or water:

Substances or wastes which, by interaction with air or water are liable to give off toxic gases in dangerous quantities.

H11 Toxic (Delayed or chronic):

Substances or wastes which, if they are inhaled or ingested or if they penetrate the skin, may involve delayed or chronic effects, including carginogenicity.

H12 Ecotoxic:

Substances or wastes which if released present immediate or delayed adverse impacts to the environment by means of bioaccumulation and/or toxic effects upon biotic systems.

H13 Capable, by any means, after disposal, of yielding another material, e.g., leachate, which possesses any of the characteristics listed above.


Potential hazards as regards certain waste products have still not been fully ascertained. Test procedures or methods for a quantification of the hazard degree do not exist. Further research is required to develop methods to define the potential hazards these waste products hold for humans and/or the environment. Standard test procedures have been developed as regards homogenous products. Many countries have developed individual test procedures that may be utilized with regard to products listed in Table 1, in order to ascertain whether these products contain some of the characeristics listed in Table 3.
