Ogni classe di merci pericolose in base alla loro proprietà fisico-chimiche, specie, e il grado di pericolo durante il trasporto sono divisi in sotto-classi, categorie e gruppi (secondo la classificazione ADR del contratto).
– absolutely pressure of vapours by the temperature 50 degrees.
– critical temperature less than 50 degrees.
– aerosol and compressed gas that are under action of special regulation.
CLASS 3 – highly inflammable liquid, mixes of liquids and liquids, contained rough substances in it and suspension, that release highly inflammable vapours, that has the temperature of flash in close capsule 61 degrees and lower.
Subclass 3.2. – highly inflammable liquids with average temperature of liquid flash in close capsule ranging from –18 to +23 degrees.
Subclass 3.3. – highly inflammable liquids with high temperature of flash-are liquids with temperature of flash ranging from 23 to 61 degrees, including in a close capsule.
Subclass 4.1. – highly inflammable rough substances, that can inflame because of external influence (such as spark, flame or friction) and actively burn.
Subclass 4.2. – self-ignitable substances, that in usual conditions of transportation can heat and inflame self-ignitable.
Subclass 4.3. – substances that in cooperation with water can emit inflammable gases.
Subclass 5.1. – oxidizing agents, that are not inflammable themselves, but promote the inflammination of other substances and emits oxygen while burning, that makes the flame more intensive.
CLASS 6 – toxic and infectious substances, that can be the reason of death, poisoning or deceases that while coming inside of the organism or while contact with skin and mucous tunic.
Subclass 6.1. – toxic substances, that can be the reason of poisoning while breathing the vapours or dust, hitting inside or in contact with skin.
Subclass 6.2. – substances and materials, containing pathogenic bacteria, that are dangerous for people and animal.
CLASS 8 caustic and corrosive substances, that damage the skin, damaging of mucous membrane of eyes and breathing passages, metal corrosion and damages of vehicles, buildings or cargoes; also can be the reason of flame while interaction with organic materials and several chemical substances.
Subclass 8.3. – different caustic and corrosion substance.
CLASS 9 substances with relative low level of dangerous while transportation, also substances, that are not referred to none of the previous classes, but that need special rules for transportation and storage.
Subclass 9.2. – Substances those become caustic and corrosive under special condition.
