Price based on 1 page 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 International Standards is carried out through IsO 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 Iso Council. International Standard tSO 4346 was developed by Technical! Committee ISO/TC 105, Steel wire ropes, and was circulated to the member bodies in August 1975. It has been approved by the member bodies of the foilowing countries : Australia Italy Switzerland Austria Japan Turkey Bulgaria Netheriands United Kingdom Czechoslovakia New Zealand U.S.A. Finland Poland U.S.S.R. France Romania Yugoslavia Germany South Africa, Rep. of India Spain The member body of the foliowing country expressed disapproval of the document on technical grounds : Belgium @ International Organization for Standardization, 1977 Printed in Switzerland Copyright International Organization for Standardization Not for Resa ISO 4346-1977 (E) INTERNATIONAL STANDARD Steel wire ropes for general purposes --- Lubricants --- Basic requirements 1 SCOPE AND FIELD OF APPLICATION 2.2 Special requirements This International Standard specifies the nature and proper- 2.2.1 The non-volatile base materiat may be dissolved in a ties of lubricants used in the manufacture of wire ropes for solvent, but if solvents are used they shall not contain general purposes.
