Publication of this edition has been sponsored by the Cast Iron Soil Pipe Institute to provide a reference book which fully meets the needs of those requiring information on the industry’s products. It was compiled and edited by the Technical Advisory Group of the Cast Iron Soil Pipe Institute, and the content has benefited from the collaborative effort of its members and their experience in the manufacture and application of cast iron soil pipe and fittings. This publication is subject to periodic revision, and the latest edition may be obtained from the Cast Iron Soil Pipe Institute.

The Cast Iron Soil Pipe and Fittings Handbook has been published to present useful information of technical and general nature on the subject of cast iron soil pipe. In recent years, the volume and diversity of this information has increased, primarily as a result of changes in the industry and its products. Technological changes in foundry practice have been introduced; conventional products have been improved; new products and new jointing methods have been developed, together with new installation procedures. Further, product standards and specifications have been revised. A handbook was considered an appropriate medium for outlining these developments and providing useful information.
