SEMI F18 - Guide for Determining the Hydrostatic Strength of, and Design Basis for, Thermoplastic Pipe and Tubing
This Standard was technically approved by the Liquid Chemicals Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on December 20, 2012. Available at www.semiviews.org and www.semi.org in April 2013; originally published in 1995.
To identify a test method for measuring the hydrostatic strength of thermoplastic pipe and tubing, a method for estimating long-term hydrostatic strength, and recommendations for developing design bases.
This Guide references the industry-recognized Standard Test Method for determining the time-to-failure of plastic pipe under constant internal pressure.
This Guide references the industry-recognized Standard Test Method for determining the long-term hydrostatic strength of plastic pipe in order to obtain the hydrostatic design basis of the pipe material.
This Guide references the Technical Report of policies and procedures for developing recommended hydrostatic design stresses for thermoplastic pipe materials from 23°C to 93.3°C (73°F to 200°F).
