9、(This Foreword is not part of ASME A112.6.1M-1997.) Much of the design evolution of sanitary plumbingware has occurred during this century as water supply and waste systems gained universal acceptance as a basic necessity. About midway through this period, the desirability of off-the-floor water clo
10、sets and their inherent advantages in improving toilet-room sanitation was recognized. Wide use of this new concept, however, was delayed for many years. When the first off-the-floor closets were designed, the problems of supporting and connecting them to waste systems had not been anticipated; and
11、as a result there were damaged walls and partitions and leaking waste systems. Slowly, a few supporting methods were developed and marketed, but in many instances, installations of off-the-floor fixtures still presented problems. Then, subsequent to World War 11, with the introduction of the combina
12、tion waste fitting and supporting system for off-the-floor water closets, installation was simplified and problems were eliminated to the extent that now this sanitary approach to modem toilet room design has become commonplace. After such a long development period, the manufacturers of fixture supp
13、orts were keenly aware of the need for sound design and engineering practices. Accordingly, the benefits of basic design standards were apparent to them and a study was initiated as an industry effort in 1961. Prior to the completion of this work, ASA Sectional Committee A1 12 (subsequently designat
14、ed the American National Standards Committee AI 12, and currently the ASME Standards Committee A1 12, Standardization of Plumbing Materials and Equipment) was organized and Panel No. 6 of this Committee was assigned the responsibility of developing standards for fixture chair carriers and other supp
15、orts for off-the-floor fixtures. The original standard resulting from this assignment was granted approval by the American National Standards Institute on March 2, 1972, and issued as ANSI A112.6.1-1972.
