Classification4.1 GeneralPipe meeting this specification is classified bytype, grade, class, and hydrostatic design basis, and by asecondary cell classification system that defines the basicmechanical properties of the pipe. These types, grades, classes,hydrostatic design basis categories, and cel

19、l classificationdesignations 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-resin pipe.Grade 8Glass-fiber-reinforced polyester

20、-resin mortarpipe.Grade 9Glass fiber reinforced epoxy resin mortar pipe.4.1.3 Classes:Class ANo liner.Class BPolyester-resin liner, nonreinforced.Class CEpoxy-resin liner, nonreinforced.Class DPolydicyclopentadiene-resin liner, nonreinforced.NOTE 5For the purposes of this classification, polyester r

21、esin includesvinylester resins, but the purchaser should consult with the manufacturerto determine which resin is applicable for the specific conditions in whichthe pipe will be used.4.1.4 Hydrostatic Design BasisTwo methods of classify-ing the hydrostatic design basis of the pipe are provided. Pipe

22、meeting this specification shall 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 design basis categories shown in Table 1.4.1.5 Mechanical PropertiesTable 2 presents a cell clas-sificati

23、on system for identifying the mechanical properties ofpipe covered by this specification.NOTE 6All possible combinations covered by the preceding classifi-cation system may not be commercially available.4.1.6 Designation CodeThe pipe designation code shallconsist of the abbreviation RTRP or RPMP, fo

24、llowed by thetype and grade inArabic numerals, the class and static or cyclichydrostatic design basis level in capital letters, and fourArabicnumbers identifying, respectively, the cell classification desig-nations of the short-term rupture strength, longitudinal tensilestrength, tensile modulus, an

25、d pipe stiffness. Thus, a completepipe designation code shall consist of four letters, twonumerals, two letters, and four numerals.4.1.6.1 ExampleRTRP-21CA-1334. Such a designationwould describe a centrifugally cast, glass-fiber-reinforced,epoxy pipe having a nonreinforced epoxy liner; a long-termcy

26、clic 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 longitudinal tensile modulus exceeding 1.5 106psi (10 300MPa); and a pipe stiffness of 72 psi (496 kPa).NOTE 7Althou

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