An assessment must be made of the health effects that the use of a substance or a preparation might entail. For that purpose the dangerous health effects have been subdivided into:
acute lethal effects;
non-lethal irreversible effects after a single exposure;
severe effects after repeated or prolonged exposure;
corrosive effects, irritant effects;
sensitizing effects;
carcinogenic effects, mutagenic effects, toxic effects for reproduction.
The systematic assessment of the dangerous health effects is expressed by means of concentration limits, expressed as weight/weight percentage except for gaseous preparations (Tables A) where they are expressed as a volume/volume percentage and in conjunction with the classification of a substance.
The classification of the substance is expressed either by a symbol and one or more risk phrases or by categories (category 1, category 2 or category 3) also expressed by risk phrases when substances are shown to be carcinogenic, mutagenic or toxic for reproduction. Therefore it is important to consider, in addition to the symbol, all the phrases denoting specific risks which are assigned to each substance under consideration.
1.1 The concentration limits fixed in Table 1 determine the classification of the preparation in relation to the individual concentration of the substance(s) present whose classification is also shown.
| Classification of the substance | Classification of the preparation | ||
|---|---|---|---|
| T+ | T | Xn | |
The R phrases denoting risk shall be assigned to the preparation in accordance with the following criteria:
| |||

The R phrases denoting risk shall be assigned to the preparation in accordance with the following criteria:

(*) According to the approved classification and labelling guide (paragraph 57) when a substance or preparation is classified as corrosive and assigned the risk phrase R34 or R35, the risk phrase R41 does not need to be included. Consequently, if the preparation contains corrosive substances with R35 or R34 below the concentration limits for a classification of the preparation as corrosive, such substances can contribute to a classification of the preparation as irritant (R41) or irritant (R36). Therefore when the formulae of paragraphs 11(b) and 13(b) of Part I of this Schedule are applied the following concentration limits must be used, unless different values are fixed in the approved supply list.
