Abstract: The keystone document in North American regulations governing the use of plastics gas distribution piping is ASTM D 2513, Standard Specification for Thermophstic Gas Pressure Pipe, Tubing and Fittings. The most frequently used gas piping is made from polyethylene (PE). Recent changes have been made to D 2513 that upgrade those PE material requirements related to durability and performance - specifically, resistance to weathering during prolonged storage and to oxidative degradation and slow crack growth (SCG) while in service. Research and experience have shown that high resistance to SCG is particularly important to resist failure under the complex stressing to which buried pipe is exposed. The new edition of D 2513 incorporates new requirements based on elevated temperature testing, which effectively exclude the use of materials with inadequate SCG resistance. The new D 2513 also includes new product and test requirements that enhance product quality. In addition, this standard now requires the use of a minimum in-plant quality control program in the production of plastics gas piping.
