2 Normative references

The following standards contain provisions which, through reference in this text, constitute provisions of this International

Standard. At the time of publication, the editions indicated were valid. All standards are subfrct to revision, and parties to

agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

ISO 5010:1992, Earth.moving machinery — Rubber-tyred machines — Steering requirements.

ISO 6165:1997. Earth-moving machinery — Basic types — Vocabulary.

ISO 9248:1992, Earth-moving machinery — units for dimensions, performance and capacities, and their measurement accuracies.

3 Definitions

For the purposes of this International Standard, the definitions given in ISO 6165 and the following apply.

turning centre

Point about which all turns of constant radius are made. (See figure 1.)

3.2

turning diameter

Diameter of the circular path described by the centre of tyre contact with the surface of the test site of the wheel describing the largest circle when the machine is executing its sharpest practicable turn under the test conditions described in dau1 or by

calculation for skid steer loaders.

3.3

turning radius

Half the turning diameter (as defined in 32). (See figure 1.)
