Pipes Plastics Pipe Institute

ASTM and the Plastics Pipe Institute, a division of the Society of the Plastics Industry, have established identifications for plastic pipe in which the first group of letters identifies the plastic, the two following numbers identify the grade of that plastic, and the last two numbers represent the design stress in the nearest lower (0.7-MPa (lOO-lbfiin ) unit at 23°C (73.4°F). 

Further information on the design of thermoplastic piping can be found in the Plastics Pipe Institute s Technical Report TR-21.

An incorporated technical organization founded in 1937 and serving the needs of the entire plastics industry in the U.S. It establishes standards for the properties and selection of materials and for product design and engineering. Its two major publications are the Plastics Engineering Handbook and the Reinforced Plastics Handbook. With it are associated the Plastics Pipe Institute and the Reinforced Plas-tics/Composites Institute. It is located at 1801 K ST NW, Suite 600K, Washington DC 20006. Website http //www.socplas.org.
