CSA MSE-, Interim Certification Requirements for Rigid PVC Pressure Pipe, PVC Injection-Moulded Gasketed Pressure Fittings, and PVCO Pressure Pipe See Attachment 1 for affected Class Numbers. Who is affected? Manufacturers of rigid polyvinylchloride (PVC) pressure pipe, PVC injection-moulded gasketed pressure fittings, and molecularly oriented polyvinylchloride (PVCO) pressure pipe. What do you do? 1. This publication provides for new certification services that do not affect your currently certified product designs. 2. Please contact CSA technical staff if you have questions or need information concerning this publication and how it applies to you. 3. If you would like to take advantage of the new certification services, initiate a certification project by contacting our Client Services Centre at Please supply appropriate supporting documentation* and we will inform you of the samples required. *which includes technical information, company name, address, factory locations and CSA file number or master contract number (if assigned), and any other relevant documentation. Introduction: Technical Information Letter (T.I.L.) CSA MSE- (see Attachment 2) has been prepared to announce CSA s early adoption of approved requirements for rigid PVC pressure pipe, PVC injection-moulded gasketed pressure fittings, and molecularly oriented polyvinylchloride (PVCO) pressure pipe. Background and Rationale: The CSA Technical Coittee on Plastic Pressure Piping recently approved additional and updated requirements in CSA B137 for rigid PVC pressure pipe, PVC injection-moulded gasketed pressure fittings, and PVCO pressure pipe, as detailed in T.I.L. CSA MSE-. Industry has requested that CSA adopt these additional and updated requirements as the basis for Certification of these products as applicable, in advance of publication of the new requirements as part of new editions of the subject standards.
