Price based on 9 pages Copyright InternationalOrganizationfor Standardization Not for Resi Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (isO member bodies). The work of deveioping International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been authorized 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 ISO Council. international Standard ISO 7224 was developed by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, and was circulated to the member bodies in April 1982. It has been approved by the member bodies of the following countries: Australia Iran Portugal Austria Irag Romania Czechoslovakia Italy South Africa, Rep. of Egypt, Arab Rep. of Korea, Dem. P. Rep. of Spain France Korea, Rep. of Switzerland Germany, F.R.

These pumps are driven by motors, usually electric, the entire 3.3 power of the moto-pump group: Maximum power motor-pump forming a moto-pump group. absorbed by the motor driving the pump.
