It is calculated by dividing the specified outsidediameter of the pipe, in
34、inches (mm), by the minimum specifiedwall thickness, in inches (mm). The standard dimension ratio(SDR) is a common numbering system which is derived fromthe ANSI preferred number series R 10.3.8 toe-ina small reduction of the outside diameter at thecut end of a length of thermoplastic pipe.4. Materi
35、als4.1 GeneralThe PE used to make pipe and fittings shall bePE or reworked PE (see 4.2 and 4.4) and shall have a PlasticsPipe Institute (PPI) long-term hydrostatic design stress andhydrostatic design basis rating.4.2 Rework MaterialClean rework material of the samecommercial designation, generated f
36、rom the manufacturersown pipe and fitting production shall not be used unless thepipe and fitting produced meet all the requirements of thisspecification. The use of these rework materials shall begoverned by the requirements of 4.3 and PPI TN-30/2006. Inpipe, rework materials shall be limited to a
37、maximum of 30 %by weight.NOTE 1The requirements for rework materials herein are intended toincorporate prudent specifications to ensure that the potential for contami-nation in gas piping products, that meet this specification, is reduced to theextent possible. It is imperative to emphasize that rew
38、ork materials havenot been identified as the cause of any field failures. The requirements forrework materials were developed by the consensus of interested partiesincluding product manufacturers, gas utility companies, and regulatoryagencies.4.3 DocumentationA documentation system to allow fortrace
