Not for Resal Price based on 1 page 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 ISO 3514 was drawn up by Technical Commitee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, and circulated to the Member Bodies in June 1974. It has been approved by the Member Bodies of the following countries : Austria Ireland Sweden Belgium Israel Switzerland Czechoslovakia Italy Turkey Denmark Mexico United Kingdom Finland New Zealand U.S.A. France U.S.S.R. Poland Germany Portugal India Romania No Member Body expressed disapproval of the document. @ International Organization for Standardization,1976 Printed in Switzerland Copyright International Organization for Standardization Not for Resale ISO 3514-1976 (E) INTERNATIONAL STANDARD Chlorinated polyvinyl chloride (CPVC) pipes and fittings Specification and determination of density 1 SCOPE AND FIELD OF APPLICATION 4 TEST PIECES This International Standard specifies a method for the Cut two test pieces from the pipe or fitting to betested, of a shape and size conforming to the requirements of the determination of the density of chlorinated polyvinyl chloride. (CPVC) pipes and fittings and lays down method chosen for the density determination. acceptable limits for this density. 5 PROCEDURE 2 REFERENCE Condition the test pieces for at least 1 h at the test temperature. ISO/R 1183, Plastics -- Methods for determining the Measure the density at 23 ± 0,1 °c, using a method which density and relative density (specific gravity) of plastics, will permit an accuracy of ± 0,002 g/cm3 to be obtained : excluding cellular plastics. preferably one of the methods described in ISO/R 1183. NOTE - The density determination may be carried out at another temperature, but the resuit thus obtained should be corrected to the 3 SPECIFICAT1ON reference temperature of 23 °c. The density at 23 °c of a chlorinated polyvinyl chioride (CPVC) pipe or fitting, P23, measured by the method 6 EXPRESSION OF RESULTS described in clause 5, shall be between the following limits : Take the arithmetic mean of the two measured values as P23 and express it two decimal places.
