This International Standard defines terms and
symbols relating to castors and wheels.
NOTE 1 “Castors and wheels” is the English expression;
in other languages the expression may be reversed, for
example in French “Roues et roulettes”.
NOTE 2 In addition to terms in English and French (two
of the three official ISO languages), this International
Standard gives the equivalent terms in German, Finnish,
Italian, Dutch and Swedish; these are published under the
responsibility of the member bodies for Germany (DIN),
Finland (SFS), Italy (UNI), Netherlands (NEN) and Sweden
(SIS). However, only the terms and definitions given in the
official languages can be considered as ISO terms and
definitions.
