Classification4.1 GeneralThis specification covers fiberglass sewerpipe defined by raw materials in the structural wall (type) andliner, surface layer material (grade), and pipe stiffness. Table 1list
19、s the types, liners, grades, and stiffnesses covered.NOTE 3All possible combinations of types, liners, grades, andstiffnesses may not be commercially available. It is acceptable to addadditional types, liners, grades, and stiffnesses as they become commer-cially available. The purchaser should deter
20、mine for himself or consultwith the manufacturer for the proper type, liner, grade, and stiffness ofpipe to be used under the installation and operating conditions that willexist for the project in which pipe is to be used.4.2 Designation RequirementsThe pipe materials designa-tion code shall consis
21、t of the standard designation, ASTMD3262, followed by type, liner, and grade indicated in Arabicnumerals, and pipe stiffness by a capital letter. Table 1 presentsa summary of the designation requirements. Thus a completematerial code shall consist of ASTM D3262, three numerals,and a capital letter.N
22、OTE 4Examples of the designation codes are as follows: (1) ASTMD3262-1-1-3-A for glassfiberreinforced aggregate and polyester resinmortar pipe with a reinforced thermoset liner and an unreinforcedpolyester resin and sand surface layer having a minimum pipe stiffness of9 psi (62 kPa). (2) ASTM D3262-
23、4-2-6-C for glassfiberreinforcedepoxy resin pipe with an unreinforced thermoset liner, no surface layer,having a minimum pipe stiffness of 36 psi (248 kPa).NOTE 5Although the Form and Style for ASTM Standards manualrequires that the type classification be roman numerals, it is recognizedthat few com
24、panies have stencil-cutting equipment for this style of type,and it is therefore acceptable to mark the product type in Arabic numbers.5.
