Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Inter-
national Standards is carried out through IS0 technical committees. Every member
body interested in a subject for which a technical committee has been set up has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council.
International Standard IS0 6012 was developed by Technical Committee ISOITC 127,
Earth-moving machinery. The first edition (IS0 6012-1978) had been approved by the
member bodies of the following countries :

Australia
Austria Germany, F.R. Spain
Israel Sweden
Belgium
Brazil Italy United Kingdom

This International Standard sets forth, for guidance, a list of
diagnostic instruments to check earth-moving machinery at the
work site.
The main purpose of this International Standard is to ensure 3 Types of checks, instruments and scales
that earth-moving machines be designed with proper ac-
cessibility and necessary connections in order to make it possi-
The table specifies for each check the corresponding in-
ble to perform these checks in an easy way, using portable in-
