Classification4.1 GeneralThis specification

21、 covers fiberglass sewer andindustrial pressure pipe defined by raw materials in thestructural wall (type) and liner, surface layer material (grade),operating pressure (class), and pipe stiffness. Table 1 lists thetypes, liners, grades, classes, and stiffnesses that are covered.NOTE 3All possible co

22、mbinations of types, liners, grades, classes, andstiffness may not be commercially available. Additional types, liners,grades, and stiffnesses may be added as they become commerciallyavailable. The purchaser should determine for himself or consult with themanufacturer for the proper class, type, lin

23、er, grade, and stiffness of pipeto be used under the installation and operating conditions that will exist forthe project in which the pipe is to be used.4.2 Designation RequirementsThe pipe materials designa-tion code shall consist of the standard designation, ASTMD3754, followed by type, liner, an

24、d grade in arabic numerals,class by the letter C with two or three arabic numerals, and pipestiffness by a capital letter. Table 1 presents a summary of thedesignation requirements. Thus a complete material code shallconsist of ASTM D3754, three numerals, C.and two or threenumerals, and a capital le

25、tter.NOTE 4Examples of the designation codes are as follows: (1) ASTMD3754-1-1-3-C50-A for glass-fiber-reinforced aggregate and polyesterresin mortar pipe with a reinforced thermoset liner and an unreinforcedpolyester resin and sand surface layer, for operation at 50 psi (345 kPa),and having a minim

26、um pipe stiffness of 9 psi (62 kPa). (2) ASTMD3754-4-2-6-C200-C for glass-fiber-reinforced epoxy resin pipe with anunreinforced thermoset liner, no surface layer, for operation at 200 psi(1380 kPa) and having a minimum pipe stiffness of 36 psi (248 kPa).NOTE 5Although the “Form and Style for ASTM St

27、andards” manualrequires that the type classification be roman numerals, it is recognizedthat few companies have stencil-cutting equipment for this style of type,and it is therefore acceptable to mark the product type in arabic numbers.5. Materials and Manufacture5.1 GeneralThe thermosetting resins,

28、glass fiberreinforcements, fillers, and other materials, when combined asa composite structure, shall produce piping products that meetthe performance requirements of this specification.4Available from American Water Works Association (AWWA), 6666 W.
