Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

International Standard ISO 6302 was prepared by Technical Committee lSO/TC 127, Earth-moving machinery, Subcommittee SC 3, Operation and main tenance.

This third edition cancels and replaces the second edition (ISO 6302:1986), of which it constitutes a technical revision.

Earth-moving machinery - Drain, fill and level plugs

1 Scope

This International Standard establishes the types, shapes and sizes of the Parts of the plugs used in connection with the hand tools listed in ISO 4510-1 to permit easy removal and installation of plugs at the work-site. lt does not set requirements, i.e. dimensions and materials, for the manufacture of plugs.

This International Standard applies to the drain, fill and level plugs required on earth-moving machines for the changing of Iubricants, coolants, hydraulic oils and fuels.
