Although the Standards Comminee had not completed its assignment, the work,of one of its task forces resulted in the development of a de facto standard which was,published by the Manufacturing Chemists Association in 1962 as an American Voluntary,Standard. More than a dozen manufacturers of chemical process pumps have been marketing,pumps conforming with the AVS since that time.,In 1965 the Hydraulic Institute published a tentative standard similar in content to the,AVS, but updated certain portions. Although the Hydraulic Institute Tentative Standard,reflected more nearly the current practice of manufacturers and users, it was believed,necessary to publish a new document which would supersede both the original AVS and,the tentative standard, and which could incorporate the technical content of both documents,in addition to dimensional criteria and features generally accepted by manufacturers and,users. The January 1968 revision of the AVS was therefore approved as an American,National Standard under the existing standards method and published as ANSI B123J-197L,ANSI B73.L superseded ANSI B123.1-1971 and was first published in 1974. The 1974,edition brought to 15 the number of pump sizes covered by the standard. Since then, the,committee has continued to be active and has added five more sizes for a total of 20, and,made a number of revisions in the text of the standard.,Shortly thereafter, the American National Standards Committee B73 undertook to revise,the standard, and as a result, new information oa baseplate rigidity, bearing frame adapter,and bearing housing drain was introduced. The 1984 edition included, for the first time.,infbnnation that covered documentation of pump and driver outline drawing of the centrifugal,pump, data sheet, medianical seal drawing, stuffing box……
