Classification4.1 GeneralThis specification covers fiberglass sewer andindustrial pres
21、sure 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 combinations of types, liners, grades, classe
22、s,and stiffness 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, liner, grade, and stiffness of pipeto be used
23、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 desig-nation code shall consist of the standard designation, ASTMD 3754, followed by type, liner, and grade in arabic numerals,class by the le
24、tter 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 D 3754, three numerals, C.and two or threenumerals, and a capital letter.NOTE 4Examples of the designation co
25、des are as follows: (1) ASTMD 3754-1-1-3-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 minimum pipe stiffness of 9 psi (62 kPa). (2)
26、 ASTMD 3754-4-2-6-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 Standards” manualrequires that the type c
27、lassification 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 resins, reinforcements, colorants, fillers,and other material
28、s, when combined as a composite structure,shall produce a pipe that shall meet the performance require-ments of this specification.5.2 Wall CompositionThe basic structural wall composi-tion shall consist of a thermosetting resin, glass-fiber reinforce-ment, and, if used, an aggregate filler.5.2.1 Re
