29、Coating Test8.1 Determine the weight of zinc coating by a strip test inaccordance with Test Method A90/A90M. The total zinc oneach specimen shall be determined in a double strippingoperation.9. Test Specimens9.1 Test specimens for determination of weight of coatingshall be cut approximately 4 in. (1
30、02 mm) in length. Specimensof toprail and brace material shall be taken from the ends ofmill lengths. Specimens of post material shall be cut from thelength from which the post is to be cut. Under no circum-stances shall specimens of post material be taken after the postis cut from the mill length.9
31、.2 Tensile and yield samples shall be of sufficient length toprepare specimens for testing in accordance with Test MethodsE8.10. Number of Tests10.1 Two test specimens for the determination of weight ofcoating shall be taken, one from each end of one length ofgalvanized pipe, selected at random from
32、 each lot of 500lengths or fraction thereof of each size.10.1.1 For purposes of testing, a lot shall consist of not morethan 500 lengths of pipe of the same type, grade, size, andweight.10.1.2 For electric-resistance welded pipe, one tensile testshall be made on one length of pipe from each lot of 5
33、00lengths, or fraction thereof, of each size. A length is defined asthe length as ordered, except that in the case of orders for cutlengths shorter than single random, the term lot shall apply tothe lengths as rolled, prior to cutting to the required shortlengths.10.1.3 For continuous-welded pipe, o
34、ne tensile test shall bemade on one length of pipe from each lot of 25 tons, or fractionthereof, of pipe 1.900 in. (48.3 mm) OD and smaller, and fromeach lot of 50 tons, or fraction thereof, of pipe 2.375 in. (60.3mm) OD and larger.11. Retests11.1 If the weight of coating of any lot does not conform
35、 tothe requirements specified in Section 7, retests of two addi-tional pipes from the same lot shall be made, each of whichshall conform to the requirements specified.12. Standard Weights12.1 The standard weights with the corresponding wallthickness for pipe of various nominal outside diameters arep
36、rescribed in Table 1 and Table 2.NOTE 3A system of standard pipe sizes has been approved by ANSIas B 36.10 that dispenses with the double-extra-strong weight andreclassifies the standard and extra-strong weights, substituting, therefore,schedules of wall thicknesses based on minimum pressure-stress
37、ratios.Wall thicknesses corresponding to most of these now listed as standardweight and extra-strong are incorporated in Schedules 40 and 80,respectively, of B 36.10.13. Dimensions, Mass, and Permissible Variations13.1 WeightThe weight of the pipe covered by Table 1and Table 2 shall not vary by more
38、 than 610 % from thatprescribed.NOTE 4The weight tolerance of 610 % is determined from theweights of the customary lifts of pipe as produced for shipment by themill, divided by the number of feet of pipe in the lift. On pipe sizes over4.500 in. (114.3 mm) OD where individual lengths may be weighed,
39、theweight tolerance is applicable to the individual length.13.2 DiameterFor pipe 1.900 in. (48.3 mm) OD andunder, the outside diameter at any point shall not vary morethan164 in. (0.4 mm) over nor more than132 in. (0.8 mm) underthe standard specified. For pipe 2.375 in. (60.3 mm) OD andover, the out
40、side diameter shall not vary more than 61 % fromthe standard specified.13.3 ThicknessThe minimum wall thickness at any pointshall not be more than 12.5 % under the nominal wall thicknessspecified.14. Lengths14.1 Lengths of toprail may be of random lengths, forexample, 16 ft (4.9 m) to 24 ft (7.3 m),
41、 unless otherwisespecified. Post lengths shall be as noted in the purchase orderor producer plans and specifications with a tolerance of 61 in.(25.4 mm).15. Workmanship, Finish, and Appearance15.1 The finished pipe shall be galvanized and reasonablystraight and free of defects. Any imperfection that
42、 is deeperthan 1212 % of the wall thickness or violates the minimumwall shall be considered a defect. All burrs at the ends of thepipe shall be removed.15.2 The zinc coating shall be free of voids or excessiveroughness.15.3 End finish shall be plain end square cut.15.4 Posts and rails shall be one p
43、iece free of weldedsections.16. Inspection and Certification16.1 All tests and inspection shall be made at the place ofmanufacture prior to shipment, unless otherwise specified, andshall be so conducted as not to interfere unnecessarily with theoperation of the works.16.2 Responsibility for inspecti
44、on, unless otherwise speci-fied in the contract or purchase order, rests upon the producer.This includes performance of all inspection and test require-ments specified herein. Except as otherwise specified in thecontract order, the producer may use their own or any othersuitable facilities for the p
45、erformance of the inspection and testrequirements specified herein unless disapproved by the pur-chaser. The purchaser shall have the right to perform any of theinspections and tests set forth in this specification where suchinspections are deemed necessary to ensure that materialconforms to prescri
46、bed requirements.17. Rejection17.1 Each length of pipe received from the manufacturermay be inspected by the purchaser and, if it does not meet theF1083 103requirements of this specification based on the inspection andtest method as outlined in this specification, the length may berejected and the m
47、anufacturer shall be notified. Disposition ofrejected pipe shall be a matter of agreement between themanufacturer and the purchaser.17.1.1 Pipe found in fabrication or installation to be unsuit-able for the intended use, under the scope and requirements ofthis specification, may be set aside and the
48、 manufacturernotified. Such pipe shall be subject to mutual investigation asto the nature and severity of the deficiency and the forming orinstallation, or both, conditions involved. Disposition shall bea matter for agreement.18. Certification18.1 The producer or supplier shall, upon request, furnis
49、h tothe purchaser a certificate of inspection stating that the materialhas been sampled, tested, and inspected in accordance with thisspecification, and has been found to meet the requirements.19. Product Marking19.1 Except as allowed by 19.6 and 19.7, each length ofpipe shall be legibly marked in the following sequence byrolling, stamping, or stenciling to show:19.1.1 Manufacturers name or mark,19.1.2 Country of origin,19.1.3 Method of manufacture (electric-resistance weldedor furnace welded),19.1.4 Specification number (year
