Price based on 17 pages Copyright International Organization for Standardization Not for Resale Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards institutes (IsO member bodies). The work of developing Inter- 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 ISo Council. International Standard Iso 4008/2 was developed by Technical Committee ISO/TC 22, Road vehicles, and was circulated to the member bodies in October 1980. It has been approved by the member bodies of the following countries : Austria Italy Sweden Belgium Korea, Dem. P. Rep. of Switzerland Czechoslovakia Korea, Rep. of United Kingdom Egypt, Arab Rep. of Netherlands USA USSR France Romania Germany, F.R. South Africa, Rep. of Iran Spain The member bodies of the following countries expressed disapproval of the document on technical grounds : Brazil Japan @ International Organization for Standardization, 1983 Printed in Switzerland Copyright Intemational Organization for Standardization ensefromIHS Not for Resale INTERNATIONAL STANDARD ISO 4008/2-1983 (E) Road vehicles - Fuel injection pump testing Part 2 : Static conditions Preamble 2.2 No distinction is made between test benches used for dif- ferent applications, for example, laboratories, manufacturers of International Standard ISO 4008 aims to achieve correct setting fuel injection equipment or service stations. and adjustment of fuel injection pumps for compression igni tion'engines by providing standardized conditions for testing. 3 References This part of IS0 4008 deals with the test bench static elements The following International Standards are essential to the total concerned with the supply and control of calibration fluid to the application of this part of Iso 4008 : pump under test and with the measurement of its performance.
