This part of ISO 1122 concerns the part of the

international vocabulary of gears which is devoted

solely to geometrical definitions.

It gives, for each of the geometrical terms relative to

gears, a standard definition which will be valid

internationally, the corresponding term in each

language being chosen as far as possible in such a

way as to directly reflect the meaning of the

definition.

NOTE — Since the choice of corresponding terms can

only be partially fulfilled in any particular language, due to

the necessity of respecting certain established

conventions, it is advisable, as far as translation into other

languages is concerned, to refer always to the meaning of

the definition itself, rather than to a simple transposition of

the original term.
