28、st of the standard designation, ASTM D3262,followed by type, liner, and grade indicated in Arabic numerals, and pipe stiffness by a capital letter. Table 1 presents a summaryof the designation requirements. Thus a complete material code shall consist ofASTM D3262, three numerals, and a capital lette
29、r.NOTE 4Examples of the designation codes are as follows: (1) ASTM D3262-1-1-3-Afor glassfiberreinforced aggregate and polyester resin mortarpipe with a reinforced thermoset liner and an unreinforced polyester resin and sand surface layer having a minimum pipe stiffness of 9 psi (62 kPa). (2)ASTM D3

31、fewcompanies 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, glass fiber reinforcements, fillers, and other materials, when combined as a compositestructu
32、re, shall produce piping products that meet the performance requirements of this specification.5.2 Wall CompositionThe basic structural wall composition shall consist of a thermosetting resin, glass-fiber reinforcement,and if used, an aggregate filler.5.2.1 ResinA thermosetting polyester or epoxy re
