33、r water at 73.4F (23C) in units of 100 psi with any decimal figures dropped. Where the hydrostaticdesign stress code contains less than two figures, a zero is used before the number. Thus, a complete material designation codeshall consist of PE and four figures for PE materials. For example, PE2708

34、is a grade PE27 polyethylene with an 800psi designstress for water at 73.4F (23C). The hydrostatic design stresses for gas are not used in this designation code.3.7 dimension ratio (DR)the ratio of pipe diameter to wall thickness. It is calculated by dividing the specified outside diameterof the pip

35、e, in inches (mm), by the minimum specified wall thickness, in inches (mm). The standard dimension ratio (SDR) is acommon numbering system which is derived from the ANSI preferred number series R 10.3.8 toe-ina small reduction of the outside diameter at the cut end of a length of thermoplastic pipe.

36、4. Materials4.1 GeneralThe PE used to make pipe and fittings shall be PE or reworked PE (see 4.2 and 4.4) and shall have a Plastics PipeInstitute (PPI) long-term hydrostatic design stress and hydrostatic design basis rating.4.2 Rework MaterialClean rework material of the same commercial designation,

37、 generated from the manufacturers own pipeand fitting production shall not be used unless the pipe and fitting produced meet all the requirements of this specification. Theuse of these rework materials shall be governed by the requirements of 4.3 and PPI TN-30/2006. In pipe, rework materials shallbe

38、 limited to a maximum of 30 % by weight.NOTE 1The requirements for rework materials herein are intended to incorporate prudent specifications to ensure that the potential for contaminationin gas piping products, that meet this specification, is reduced to the extent possible. It is imperative to emp

39、hasize that rework materials have not beenidentified as the cause of any field failures. The requirements for rework materials were developed by the consensus of interested parties including productmanufacturers, gas utility companies, and regulatory agencies.4.3 DocumentationA documentation system
