1、Designation: C1450/C1450M 04 (Reapproved 2010)Standard Specification forNon-Asbestos Fiber-Cement Storm Drain Pipe1This standard is issued under the fixed designation C1450/C1450M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, th
2、e year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers non-asbestos fiber-cement pipeintended for use in storm-water drainage of highways
3、, airports,farms, foundations, and other similar drainage systems.1.2 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore each syste
4、m shallbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.NOTE 1Experience has shown that the successful performance of thisproduct depends upon the proper selection of the pipe strength, the type ofbedding and backfill, care
5、 that the installation conforms to the construc-tion specifications, and provision for adequate inspection at the construc-tion site. This specification does not include requirements for bedding,backfill, the relationship between field load conditions and the strengthdesignation of the pipe, or dura
6、bility. These requirements should beincluded in the project specification.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine
7、 the applica-bility of regulatory limitations prior to use.2.

17、0, West Conshohocken, PA 19428-2959, United States.4. Classification4.1 The types of pipe shall be shown as Type I and Type IIcorresponding to the chemical requirements given in S3.NOTE 2There are no chemical requirements for Type I pipe. Type IIpipe is generally accepted as being unaffected by sulf
18、ates in groundwaterwhich cause matrix expansion and consequential pipe deterioration.4.2 Fiber-cement storm drain pipe furnished under thisspecification shall be designated as Class I, II, III, IV, and V.The corresponding strength requirements are prescribed inTable 1. The D load is the saturated cr
19、ushing test loadexpressed in pounds-force per linear foot per foot of diameter.The D1 load is the saturated crushing test load expressed inNewtons per linear metre per millimetre of diameter. The pipeshall be furnished in 4, 6, 8, 10, 12, 15, 18, 21, 24, 27, 30, 33,36, 42 and 48-in. 100, 150, 200, 2

21、la-tion methods.5. Composition and Manufacture5.1 CompositionFiber-cement drain pipes shall be com-posed of an intimate mixture of an inorganic hydraulic binder(see Specification C150) or a calcium silicate binder (seeSpecification C595) formed by the chemical reaction of asiliceous material and a c
22、alcareous material reinforced byorganic fibers, inorganic non-asbestos fibers, or both. Processaids, fillers, and pigments which are compatible with fiber-reinforced cement are not prohibited from being added.5.1.1 The manufacturer shall state the type of fiber used inthe pipe, and, where requested,
23、 provide the owner withdocumented evidence that the fibers employed are compatiblewith other materials of that manufacturer.5.2 ManufactureThe pipe wall shall be of laminar con-struction formed under pressure to be a homogeneous struc-ture, and cured either under natural or accelerated conditions,to
24、 meet the physical requirements of this specification.6. Dimensions, Mass, and Tolerances6.1 The nominal length for fiber-cement storm drain pipeshall be designated by the manufacturer. Unless otherwiseagreed by the Owner, furnish a maximum of 15 % of the totalfootage of any one size and type for an
25、y order, at themanufacturers option, in pipe lengths shorter than the nominallengths.6.2 The underrun in length of a section of pipe shall not bemore than18 in./ft 10 mm/m with a maximum of12 in. 12.7mm in length in any pipe.6.3 The average inside diameter shall not be less than thenominal size by m
26、ore than 0.25 in. 6 mm or 112 %ofthenominal size, whichever is greater in value.6.4 The manufacturer shall state the minimum wall dimen-sions of the product it produces that complies with theminimum crush loads presented in Table 1.7. Sampling7.1 All material tested under this specification shall be
27、tested in the saturated condition after immersion in water at anambient temperature above 41F 5C for a period of 21 to 28days immediately prior to testing.7.1.1 Employ sampling procedures providing an averageoutgoing quality limit (AOQL) of 6.5 %, except where specificsampling is required by particu
28、lar test procedures. AppendixX2 describes a sampling plan which provides an AOQL of 6.5%.7.1.2 The minimum sample size for sampling and accep-tance by attributes or variables shall be in Table 2.7.1.3 Pipes of different sizes or classes but of sequentialmanufacture in a continuous manufacturing proc
29、ess may besampled as being in the same inspection lot.7.2 For crushing tests sample the required number of fulllengths of pipe according to the inspection lot size. Cut one testspecimen no shorter than 6 inches 150 mm long from theunmachined end of each of the selected pipe lengths.(WarningIn additi
30、on to other precautions, when cuttingfiber-cement products minimize the dust that results. Prolongedbreathing or frequent breathing of significant airborne concen-trations of silica is hazardous. When such dust is generated,effective measures shall be taken to prevent inhalation.)NOTE 3When sampling
31、 from continuous production, these tests maybe conducted on dry, equilibrium, or saturated specimens, provided arelationship can be established between this testing and the specifiedvalues.NOTE 4A manufacturers process with an AOQL of 6.5 % indicatesthat better than 93.5 % of the inspected productio
32、n exceeds the specifi-cations for marginally accepted product. This type of specificationprovides the protection and confidence of a clearly defined lowerboundary. This would not be true if acceptance were based solely on theaverage value of the measured property. Examples of sampling schemeswhich m
33、ay be used can be found in documents such as MIL-STD- 105,MIL-STD-414, or ISO 390. Other sampling schemes may be used whichmaintain equally rigorous quality levels. Inspection by attributes consistsof determining, for every item of a sample, the presence or absence of acertain qualitative characteri
34、stic (attribute) with respect to the applicablespecification. It is, in essence, a pass-fail inspection which determines thenumber of items in a sample that do or do not conform to the specification.An attribute could be a dimensional measurement, or a flexural strengthvalue, or others that are desc
35、ribed in these test methods. Inspection byvariable consists of measuring a quantitative characteristic for each itemin a sample. Conformance with the applicable specification is determinedfrom the mean values of the measured properties and the statisticalTABLE 1 Minimum Crushing LoadPipe Class D Loa

Couplings8.1 Each standard, short, or random length of pipe shall beprovided with a coupling or joint for the purpose of maintain-ing alignment and to ensure close joints.8.2 Joints s
39、hall be of a design, and the ends of the pipesections so formed, that when the sections are laid togetherthey will make a continuous line of pipe with a smooth interiorfree of appreciable irregularities in the flow line and all will becompatible with the tolerances given in Section 6.9. Fittings9.1

Test Methods10.1 Crushing StrengthConduct crushing tests beforeshipment. No shorter than 6 in. 150 mm lengths of pipe cutfrom unmachined portions of the pipe
41、shall be tested inaccordance with the appropriate section of Test Methods C497.11. Inspection11.1 All material furnished under this specification shallconform to the requirements stated herein and shall be sub-jected to factory inspection and tests prescribed in this speci-fication. When specified i
42、n the purchase order (see AppendixX1), the manufacturer shall notify the purchaser of the timethat the inspection and testing will take place to allow thepurchaser to arrange for witnessing such tests and inspectionsat his own expense. Instead of such inspection, when re-quested, the manufacturer sh
43、all certify that his product con-forms to the requirements of this specification.11.2 Each pipe shall be inspected by the manufacturerbefore shipment for compliance with the standards for dimen-sions, tolerances, workmanship, and finish (see also Section 7).11.3 The manufacturer shall maintain a Qua
