Following publication of the 1949 edition a demand developed for a stillighter wall pipe. A Schedule S was deter- mined cooperatively by representatives of chemical panies processing industries and manufacturers of welding fittingsThis was endorsed bythe American Standards Association (ASA)Chemical Industry Correlating Committee and theManufacturers Standardization Society of the Valve and Fitings IndustryThe new schedule was included in the revised standard that was approved by ASA [now American National Standards Institute (ANSI] on April 7 1952. In 1956 it was remended that the wall thickness of 12 in. 5S be lessened and a new revision of the standard was issued shortlyfteitsapproval byASAnFbruary271957.Inthis fourthdition dimensionswere expanedbeyond 12inipizebyinlsinfndrentAifiatn9hisevisiowasaprovedbyAn 29 1965.
