ISO
6194
defines
technical
terms
and
nomenclature,
in English and French, usad in relation to rotary
shaft lip seals, and gives the equivalent terms in Russian,
German, Swedish, Japanese and Italian.
The terms apply to the types, the various parts of sealing
devices, the tolerances and fits, the storage, handling and fitting, the visual variation and failure of seals, and the general
performance test procedure of rotary shaft lip type seals.
NOTE
–
In addition
to terms and definitions
used in two of the three
official ISO languages (English and French), this part of ISO 6194 gives
the equivalent terms in the Russian, German, Swedish, Japanese and
Italian languages; these are published under the responsibility of the
member bodies for the Soviet Union (GOST), Germany (DIN), Sweden
(S1S), Japan (J ISC), and Italy (UNI). However, only the terms given in
the official languages (English, French and Russian) can be considered
as ISO terms.
