Now that we are firmly entrenched in the electronic age, a new generation of engineers have had virtually no exposure to terminology or diagrams relating to analog and digital equipment which is still used in many plants and factories in the industries served by MCAA members. As an Association, we believe that information developed back in the 70s and 80s ought to be widely available even though new technologies are available today. Thus, In 2003 MCAA acquired the rights to a number of standards published by organizations formerly under the umbrella of the Scientific Apparatus Makers Association (SAMA), namely the "Recorder-Controller, Inc." which produced standards with an "RC" prefix and its successor the "Process Measurement & Control Section" which produced standards with a PMC prefix. MCAA is the new corporate identity for these two organizations.
SAMA had taken the standards out of circulation and declared that they were out of date. That organization will no longer permit its name to be associated with the documents. MCAA felt that several of the documents offered ongoing information guidance to individuals in the process measurement and control or automation industries and hence our acquisition of the rights. We have disclaimers and cautions as well:
MCAA provides these documents as reference guides only. None of them should be relied upon or used as a substitute for research or independent professional advice. MCAA offers these documents to the public as information guides only.
Terminology, techniques or technology mentioned in this document may no longer be applicable or up-to-date and the reader is cautioned to draw only limited inferences therefrom and should, at all times, bear in mind the length of time that has elapsed since the document in question was first developed.
