For word

ISO ( the International Org anization for Stand rdization) is a worldwide

federation of national stand rds bodies ( ISO member bodies) The work of

prep ring International Stand rds is normal y car ied out throug h ISO tech ical

commit e s Each member bod interested in a subject for which a technical

commit e has be n esta lshed has the rig ht to be represented on that

commit e International org anizations, g ov ernmental and non-g ov ernmental,

in laison with ISO, also take p rt in the work ISO cola orates closely with the

4.2 Servic descriptions

The serv ice des ription shal be indicated as folows:

4.2.1 Load index

The loa index is a n merical code as ociated with

the ma imum loa a ty re can car y at the spe d

indicated b its spe d sy mbol, u der the serv ice

conditions specified b the ty re man facturer

The spe d sy mbol shal be as g iv en in Ta le 2 The

spe d sy mbol or spe d categ ory indicates the

reference spe d, defined as the spe d at which the

ty re can car y the loa cor esponding to its loa

index u der the specified serv ice conditions

5 Marking

The marking shal consist of

a) the desig nation of the dimensional and

constructional characteristic ac ording to

ISO10 9 -1;

b) the desig nation of the serv ice des ription ( loa

index and spe d sy mbol

The location of the marking of the serv ice

des ription ( loa index and spe d sy mbol shal be

distinct but in the v icinity of the marking of the

dimensional and constructional characteristic
