Price based on 2 pages nal Oraanization for Standardization Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards institutes (Iso member bodies). The work of developing Inter- national 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 theIso Council. International Standard ISo759 was developed byTechnical Committee ISO/TC 47, Chemistry,andwascirculatedtothememberbodiesinDecember1979 It has been approved by the member bodies of the following countries : Australia France Poland Austria Germany, F. R. Portugal Belgium Hungary Romania Brazil India South Africa, Rep. of Bulgaria Italy Switzerland China Korea, Rep. of Thailand Czechoslovakia Netherlands United Kingdom Egypt, Arab Rep. of Philippines USSR No member body expressed disapproval of the document. This International Standard cancels and replaces ISO Recommendation R 759-1968, of which itconstitutes a technical revision. This International Standard has also been approved by the International Union of Pure and Applied Chemistry (IUPAC). International Organization for Standardization,1981 Printed in Switzerland Copvriaht International Oroanization for Standardization ISO759-1981 (E) INTERNATIONALSTANDARD Volatile organic liquids for industrial use - Determination of dry residue after evaporation on a water bath Generalmethod WARNING - Attention is drawn to the potential hazards associated with the volatility,flammability, reactivity or toxicity of many of the products to which this test can be applied. It is, therefore, essential that, before using the method, careful consideration is given to the precautions necessary to eliminate the potential hazards. Furthermore, all operations shall be carried out in a well-ventilated fume cupboard. Scope and field of application 4Apparatus This International Standard specifies a general method for the Ordinary laboratoryapparatus,and determination of the dry residue, after evaporation on a water bath, of volatile organic liquids for industrial use. 4.1 Dish, of platinum, silica or borosilicate glass, of capacity The method is applicable to products having dry residues about150ml. after evaporation greater than or equal to 10 mg/kg [0,001 % (m/m)]. 4.2 Water bath, maintained at a temperature appropriate to the boiling point of the product under examination. NOTES WARNING -- The heating system shall be designed so as For the determination of the non-volatile residue of fluorinated toavoid all possibilityofafirehazard. hydrocarbons for industrial use, see Iso 5789 2 For the determination of the residue on evaporation of aromatic 4.3 Electric oven, capable of being maintained at hydrocarbons,or other toxic volatile materials,having residues on 110 ±2oC evaporationofnotlessthan1mg/100mi,seeISo5277 Sampling2) 2References Iso758,Liquid chemical products for industrialuse-- Deter- specific to a particular productbeing exam
