The Mark of Quality
The Institute utilizes a quality control program to verify its member foundries are manufacturing cast iron soil pipe and fittings, which are marked with the Institute’s collective trademark, meet the appropriate CISPI 301 and ASTM A74 standards. The Institute conducts unannounced inspections three times annually during the course of the year to the requirements found in the CISPI 301 and ASTM A74 standards.
Annex A1, found in both CISPI 301 and ASTM A74, details the requirements for third party certification for the manufacturing of cast iron soil pipe and fittings to the CISPI 301 and ASTM A74 standards.
Annex A1 requires that the third party inspector shall verify compliance with the standards’ manufacturing requirements for tensile strength testing, chemical analysis, the screening of ferrous material for radioactivity, and physical dimension requirements. Annex A1 also requires the third party inspector to physically measure 10 different sizes and configurations of pipe and fittings for each class of cast iron soil pipe and fittings manufactured at the location. In addition, CISPI 301 requires that third party inspector shall also verify coatings used shall not contain lead above 600 ppm.
