PART BU.K.Lexicon guide for establishing the alternative designations (generic names)
1.Introductory noteU.K.
The lexicon guide is based on the procedure for the classification of dangerous substances (division of substances into families) which appears in Annex I to Directive 67/548/EEC.
Alternative designations to those based on this guide may be used. However, in all cases the names chosen must provide enough information to ensure the preparation can be handled without risk and that necessary health and safety precautions can be taken in the workplace.
The families are defined in the following manner:
inorganic or organic substances whose properties are identified by having a common chemical element as their chief characteristic. The family name is derived from the name of the chemical element. These families are identified as in Annex I by the atomic number of the chemical element (001 to 103),
organic substances whose properties are identified by having a common functional group as their chief characteristics.
The family name is derived from the functional group name.
These families are identified by the conventional number found in Annex I (601—650).
Sub-families bringing together substances with a common specific character have been added in certain cases.
2.Establishing the generic nameU.K.
General principles
For the purposes of establishing the generic name, the following general approach, involving two successive stages, is adopted:
identification of the functional groups and chemical elements present in the molecule;
determination of the extent to which account should be taken of the most important functional groups and chemical elements.
The identified functional groups and elements taken into account are the names of the families and sub-families set out in point 3 in the form of a non-restrictive list.

4.Practical application:U.K.
After having conducted a search to see if the substance belongs to one or more families or sub-families on the list, the generic name can be established in the following way:
4.1.If the name of a family or sub-family is sufficient to characterise the chemical elements or important functional groups, this name will be chosen as the generic name.U.K.
Examples:
1,4 dihydroxybenzen
family 604:
phenols and derivatives
generic name:
phenol derivatives
butanol
family 603:
alcohols and derivatives
sub-family:
aliphatic alcohols

methacrylate
family 607:
organic acids and derivatives
sub-family:

4.2.If the name of a family or sub-family is not sufficient to characterise the chemical elements of important functional groups, the generic name will be a combination of the corresponding different family or sub-family names:U.K.
