Classification4.1 GeneralPipe meeting this specification is classified bytype, grade, class, and hydrostatic design basis in accordancewith Classification D 2310, and by a secondary cell classifica-tion system that defines the basic mechanical properties of thepipe. These types, grades, classe

20、s, hydrostatic design basiscategories, and cell classification designations are as follows:4.1.1 Types: Type IICentrifugally cast pipe.4.1.2 Grades: Grade 1Glass-fiber-reinforced epoxy-resin pipe.Grade 2Glass-fiber-reinforced polyester-resin pipe.Grade 3Glass-fiber reinforced polydicyclopentadiene-r

22、rostatic Design BasisTwo methods of classify-ing the hydrostatic design basis of the pipe are provided. Pipemeeting this specification may be classified using either thecyclic test method or the static test method, or both, and thedesignations are shown in Table 1. Appendix X1 explains howto use the

23、 design basis categories shown in Table 1.4.1.5 Mechanical PropertiesTable 2 presents a cell clas-sification system for identifying the mechanical properties ofpipe covered by this specification.NOTE 5All possible combinations covered by the preceding classifi-cation system may not be commercially a

24、vailable.4.1.6 Designation CodeThe pipe designation code shallconsist of the abbreviation RTRP or RPMP, followed by thetype and grade inArabic numerals, the class and static or cyclichydrostatic design basis level in capital letters, and four Arabicnumbers identifying, respectively, the cell classif

25、ication desig-nations of the short-term rupture strength, longitudinal tensilestrength, tensile modulus, and pipe stiffness. Thus, a completepipe designation code shall consist of four letters, two numer-als, two letters, and four numerals.4.1.6.1 ExampleRTRP-21CA-1334. Such a designationwould descr

26、ibe a centrifugally cast, glass-fiber-reinforced,epoxy pipe having a nonreinforced epoxy liner; a long-termcyclic pressure strength level exceeding 2500 psi (17.2 MPa);a short-term rupture strength exceeding 4000 psi (27.6 MPa); alongitudinal tensile strength exceeding 16 000 psi (110 MPa);a longitu

27、dinal tensile modulus exceeding 1.5 by 106psi(10 300 MPa); and a pipe stiffness of 72 psi (496 kPa).NOTE 6Although the Form and Style for ASTM Standards manualrequires that the type classification be roman numerals, it is recognizedthat few companies have stencil-cutting equipment for this style of

28、type,and it is therefore acceptable to mark the product type in arabic numbers.5.
