Price based on 2 pages 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 ISO 3603 was developed by Technical Committee IsO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, and was circulated to the member bodies in December 1974. It has been approved by the member bodies of the following countries : Austria Israel South Africa, Rep. of Belgium Italy Spain Canada Japan Sweden Finland Mexico Switzerland France New Zealand Turkey Germany Norway U.S.A. India Poland U.S.S.R. Ireland Romania The member bodies of the following countries expressed disapproval of the document on technical grounds : Denmark Netherlands United Kingdom Not for Resale Printed in Switzeriand ISO 3603-1977 (E) INTERNATIONAL STANDARD Fittings for unplasticized polyvinyl chloride (PVC) pressure pipes with elastic sealing ring type joints -- Pressure test for leakproofness 1 SCOPE AND FIELD OF APPLICATION polyvinyl chloride (PVC) pipe for which. the joint is designed. This International Standard specifies the method tor proof testing fittings with elastic sealing ring type joints The test temperature shall be 20 ± 2 °c. for unplasticized polyvinyl chloride (PVC) pressure pipes, The duration of the test shall be not less than 1 h, during under internal hydrostatic pressure which time the joint shall be free from leaks. It specifies the minimum requirements of the tested joint. The joint shall satisfy the test requirements when the spigot with a specified internal pressure higher than the nominal and socket conform to the extreme limits of the respective pressure for which the pipes are designed. tolerances (see clause 5). 2 PRINCIPLE 4 APPARATUS Exposure of a specimen consisting of a pipe and fitting 4.1 Suitable device, connected to the test specimen, assembly having at least one joint of this type to a specified capable of applying a constant internal water pressure of at internal hydrostatic load at a specified temperature. Checking of the joint tightness during the test period, when chloride (PvC) pipe for which the ftting is designed, for the pressure is higher than the nominal pressure for which not less than 1 h. the pipe is designed. 4.2 Suitable device, to compensate for the axial stresses 3 SPECIFICATIONS imposed by the application of internal hydrostatic pressure. Testing shall be performed unaer an internal pressure of at 4.3 Pressure gauge, having an accuracy of ± 2 %. Copyright International Organization for Standardization Not for Resale e from IHS
