HISTORY OF PROJECT The Society of the Plastics Industry, Inc., requested the assistance of the Department of Commerce in establishing a Voluntary Product Standard for polytetrafluoroethylene (PTFE) plastic tubing. A proposed draft of the Standard was developed and in May 1971, the proposed Standard was approved by the Standard Review Committee. In July 1971, public announcement was made, and the recommended Voluntary Product Standard was widely circulated to the industry for acceptance. The response to this circulation indicated a consensus of acceptability within the industry as defined in the Procedures for the Development of Voluntary Product Standards. Accordingly, the Standard, designated PS 52–71, Polytetrafluoroethylene (PTFE) Plastic Tubing was approved for publication by the National Bureau of Standards to be effective November 15, 1971.
