Committee to develop three separate test codes on Condensing Apparatus,Feedwater Heaters,and Water Cooling Equipment.The resulting Test Code for Steam-Condensing Apparatus,after passing through the preliminary stages in the procedure prescribed by the Main committee,was printed in tentative form in the May 1924 issue of Mechanical Engineering and was presented to the Society for discussion at a public hearing held during the Spring Meeting in Cleveland in May 1924.At the December 1924 meeting of the PTC Supervisory Committee(now known as the Board on Performance Codes),it was approved in its final revised form and on October 5,1925,it was approved and adopted by the Council as a standard practice of the Society.Early in 1933 Committee No.12 decided to completely revise the Test Code for Steam-Condensing Apparatus.At the April 4,1938,meeting of the PTC Supervisory committee,this second version of the Code was approved and on July 15,1938,it superseded the previous one and was adopted as a standard practice of the Society by the Council.With the reorganization of PTC Committee No.12 on Condensers,Feedwater Heaters,and Deaerators in 1948,the main Power Test Codes Committee requested that the Test Code for Steam-Condensing Apparatus be brought up to date.This third edition of the Code was approved at the December 4,1953,meeting of the Power Test Codes Committee and adopted by the Council as a standard practice of the Society on March 9,1954.In January 1970 the PTC Supervisory Committee requested the Test Code for Steam-Condensing Apparatus be reviewed and updated.That fourth version of the Code was approved by the Board on Performance Test Codes on May 7 2,1981,and it became an Am
