8.2 Rockwell Hardness Requirement:
8.2.1 Product furnished from Alloy C63020 in TQ30 temper shallshould have a minimum hardness of 26 on the Rockwell C
scale when tested in accordance with Test Methods E18.
8.2.1.1 The approximate Rockwell hardness values given are for general information and assistance in testing and shall not be
used as a basis for product rejection. The test is optional.
NOTE 2—The Rockwell hardness test offers a quick and convenient method of checking for general conformity to the specification requirements for

9. Other RequirementsNondestructive Test
9.1 Nondestructive Testing:
9.1.1 Unless otherwise agreed upon between the supplier and the purchaser, the pipe or tube The tubes shall be tested for defects
either in the final drawn, annealed, or specified temper or in the drawn temper drawn tempers or as drawn before the final anneal.
Unless otherwise specified, the manufacturer shall have the option of testing the pipe or tube by one of the following tests:annealed
temper unless otherwise agreed upon between the manufacturer and the purchaser.
9.1.2 Electromagnetic Examination (Eddy Current)—(Eddy-Current Test): Each tube or pipe in nominal sizes from ⁄8 in. (3.2
mm) up to and including 2 ⁄2 in. (63.5 mm), regular and extra-strong, shall be subjected to an eddy-current test. Tests shall follow
the procedures of Practice E243 except for the determination of “end effect.” The pipe or tube shall be passed through an
eddy-current testing unit adjusted to detect an artificial defect of a size and shape defined as follows:
9.1.2.1 Each tube up to and including 3 ⁄8 in. (79 mm) in outside diameter shall be subjected to test.
NOTE 4—End effect is that length of the pipe or tube that travels through the coil until the testing unit has stabilized and is able to detect flaws. The
magnitude of the spike generated when an end passes through the test coils is such that it disrupts testing momentarily.
9.1.2.2 When tested in accordance with Practice E243, tubes which do not actuate the signaling device of the testing unit shall
be considered as conforming to the requirements of the test.
9.1.2.3 Artificial Defects—Round bottom-notch standards with a profile as defined in Practice E243, rounded to the nearest
0.001 in. (0.025 mm) shall be 10 % of the specified wall thickness. Notch-depth tolerances shall be 60.0005 in. (0.013 mm).
Alternatively, when a manufacturer uses speed-insensitive equipment that can select a maximum unbalance signal, a maximum
unbalance signal of 0.3 % shall be used.
9.1.2.2 Retesting—Pipes or tubes that do not activate the signaling device of the eddy-current tester shall be considered as
conforming to the requirements of this test. Lengths with discontinuities, indicated by the testing unit, at the option of the
manufacturer, may be reexamined or retested to determine whether the discontinuity is cause for rejection. Signals that are found
to have been caused by soil, moisture, or minor mechanical damage shall not be cause for rejection, provided the pipe or tube
dimensions are still within the prescribed limits and the pipe or tube is suitable for its intended application.
9.1.3 Pressure Tests—Each pipe or tube selected in accordance with 13.1.3 shall withstand the pressure test of either 9.1.3.1 or
9.1.3.2.
9.1.3.1 Hydrostatic Pressure Test—Each pipe or tube shall withstand, without showing evidence of leakage,When specified in
the contract or purchase order, each tube shall be capable of withstanding an internal hydrostatic pressure sufficient to subject the
material to produce a fiber stress of 7000 psi (48 mPa). The pipe orMPa) without leakage. The tube need not be tested atsubjected
to a hydrostatic pressure of gauge reading over 1000 psi (6.9 MPa) unless so specified. specifically stipulated in the contract or
B315 − 19
purchase order. At the option of the manufacturer, annealed pipe with wall thickness up to 0.083 in. (2.11 mm), inclusive, may be
tested in the drawn condition, before annealing. Fiber stress shall be determined by the following equation for thin, hollow
cylinders under tension:
P 5 2St/~D 2 0.8t! (1)
where:
P = hydrostatic pressure, psi (MPa);
t = thickness of pipe or tube wall, in. (mm);
D = outside diameter of the pipe or tube, in. (mm); and
S = allowable fiber stress of the material, psi (MPa).
9.1.3.2 Pneumatic Pressure Test—Each pipe or When specified in the contract or purchase order, each tube shall be pressurized
to a minimum of 60 psi (415 kPa), air for 5 s, without showing evidence of leakage. The test method used shall permit easy visual
detection of any leakage, such as by submerging the tube under water or by pressure differential method.capable of withstanding
an internal air pressure of 60 psi (400 kPa), minimum for 5 s without leakage.
10. Dimensions, Mass, and Permissible Variations
10.1 General:
10.1.1 The standard method of specifying wall thickness shall be in decimal fractions of an inch.
10.1.2 For the purpose of determining conformance with the dimensional requirements prescribed in this specification, any
measured value outside the specified limiting values for any dimension may be cause for rejection.
10.1.3 Tolerances on a given tube may be specified with respect to any two, but not all three, of the following: outside diameter,
inside diameter, wall thickness.
NOTE 3—Blank spaces Spaces that contain an ellipsis (.) in the tolerance tables indicate either that the product is not generally available or that no
