as the difference between the sum of all the elements analyzed
and 100 %.
5.2.1.1 When all the elements in the table in 5.1 are
analyzed, their sum shall be 99.8 % minimum. Standard Specification for Seamless Red Brass Pipe, Standard Sizes
6. Temper
6.1 All pipe shall normally be furnished in the O61 (an-
nealed) (see Classificiation B 601) condition.
6.2 In the O61 (annealed) temper, the degree of annealing
shall be sufficient to produce complete recrystallization with an
average grain size not in excess of 0.050 mm. The surface of
the test specimen for grain size determination shall approxi-
mate a radial longitudinal section and shall be prepared and
examined in accordance with Test Methods E 112.
6.3 The pipe is permitted to be furnished in the H58 (drawn
general purpose) temper, if agreed upon between the manufac-
turer and the purchaser. (See Table 1.)

test.
NOTE 1—The term “unaided eye,” as used herein, permits the use of
corrective spectacles necessary to obtain normal vision.
8.2 As an alternative to the expansion test for pipe over 4 in.
(102 mm) in diameter in the O61 (annealed) condition, a
section 4 in. in length shall be cut from the end of one of the
lengths for a flattening test. This 4-in. specimen shall be
flattened so that a gage set at three times the wall thickness will
pass over the pipe freely throughout the flattened part. The pipe
so tested shall develop no cracks or flaws visible to the unaided
eye (see Note 1) as a result of this test. In making the flattening
test the elements shall be slowly flattened by one stroke of the
press.
9. Mercurous Nitrate Test
9.1 Warning—Mercury is a definite health hazard and
therefore equipment for the detection and removal of mercury
vapor produced in volatilization is recommended. The use of
rubber gloves in testing is advisable.
9.2 When the test is required to be performed, the test
specimens, cut 6 in. (152 mm) in length, shall, after proper
cleaning, withstand an immersion for 30 min without cracking

10.1 The material shall be tested in the final size but is
permitted to be tested prior to the final anneal or heat treatment,
when these thermal treatments are required, unless otherwise
agreed upon by the manufacturer or supplier and purchaser.
10.2 Eddy-Current Test—Each piece of material from 1⁄8 in.
up to and including 21⁄2 in. nominal outside diameter or within
the capabilities of the eddy-current tester, shall be subjected to
an eddy-current test. Testing shall follow the procedures of
Practice E 243 except for determination of “end effect.” The
material shall be passed through an eddy-current testing unit
adjusted to provide information on the suitability of the
material for the intended application.
10.2.1 Notch-depth standards rounded to the nearest 0.001
in. (0.025 mm) shall be 10 % of the nominal wall thickness.
The notch depth tolerances shall be 60.0005 in. (0.013 mm).
Alternatively, when a manufacturer uses speed insensitive
equipment that allows the selection of a maximum imbalance
signal, a maximum imbalance signal of 0.3 % is permitted to
be used.

requirements of this test. Material with discontinuities indi-
cated by the testing unit is permitted to be reexamined or
retested, at the option of the manufacturer, to determine
whether the discontinuity is cause for rejection. Signals that are
found to have been caused by minor mechanical damage, soil
or moisture shall not be cause for rejection of the material
provided the dimensions of the material are still within
prescribed limits and the material is suitable for its intended
application.
10.3 Hydrostatic Test—When specified, the material shall
stand, without showing evidence of leakage, an internal hydro-
static pressure sufficient to subject the material to a fiber stress
of 6000 psi (41 MPa), determined by the following equation
for thin hollow cylinders under tension. The material need not
be tested at a hydrostatic pressure of over 1000 psi (6.9 MPa)
unless so specified.

where:
P = hydrostatic pressure, psi (or MPa),
t = wall thickness of the material, in. (or mm),
D = outside diameter of the material in. (or mm), and
S = allowable stress of the material, psi (or MPa).
10.3.1 For material less than 1⁄2 in. (12.7 mm) in outside
diameter and less than 0.060 in. (1.5 mm) in wall thickness, the
test is permitted to be made at the option of the manufacturer
by pneumatically testing to the requirements of 10.4.
10.4 Pneumatic Test—When specified, the material shall be
subjected to an internal air pressure of 60 psi (415 kPa)
minimum for 5 s without showing evidence of leakage. The test
method used shall permit easy visual detection of any leakage,
such as by having the material under water or by the pressure-
differential method. Any evidence of leakage shall be cause for
rejection.
11. Dimensions and Permissible Variations
11.1 For the purpose of determining conformance with the
dimensional requirements prescribed in this specification, any
measured value outside the limiting values for any dimensions
may be cause for rejection.
11.2 Standard Dimensions, Wall Thickness, and Diameter
Tolerances—The standard dimensions, wall thickness, and
diameter tolerances shall be in accordance with Table 2.
11.3 Length and Length Tolerances—The standard length of
red brass pipe is 12 ft (3.66 m) with a tolerance of 61⁄2 in. (13
mm).

11.5 Roundness—The roundness tolerance for straight
length tubes with a wall thickness to outside diameter ratio of
0.01 to 0.05 (inclusive) shall be 6 % of the nominal outside
diameter. For tubes with a wall thickness to outside diameter
ratio over 0.05, the roundness tolerance shall be 3 % of the
nominal outside diameter.
11.5.1 The measurement for roundness shall be made from
the outside diameter. The deviation from roundness is mea-
sured as the difference between the major and minor diameters
as determined at any one cross section of the tube. The major
and minor diameters are the diameters of two concentric circles
just enclosing the outside surface of the tube at the cross
section.
11.6 Straightness Tolerance—For pipe of H58 (drawn gen-
eral purpose) temper of Nominal Pipe Sizes from 1⁄4 to 12 in.
inclusive, the maximum curvature (depth of arc) shall not
exceed 1⁄2 in. (13 mm) in any 10-ft (3048-mm) portion of the
total length. For H58 temper pipe of other sizes, and for the
O61 (annealed) temper, no numerical values are established,
however, the straightness of the pipe shall be suitable for the
intended application.

14.1 Chemical Analysis—Samples for chemical analysis
shall be taken in accordance with Practice E 255. Drillings,
millings, etc., shall be taken in approximately equal weight
from each of the sample pieces selected in accordance with
13.1.2 and combined into one composite sample. The mini-
mum weight of the composite sample that is to be divided into
three equal parts shall be 150 g.
14.1.1 Instead of sampling in accordance with Practice
E 255, the manufacturer shall have the option of determining
conformance to chemical composition as follows: Conform-
ance shall be determined by the manufacturer by analyzing
samples taken at the time the castings are poured or samples
taken from the semi-finished product. If the manufacturer
determines the chemical composition of the material during the
course of manufacture, he shall not be required to sample and
analyze the finished product. The number of samples taken for
determination of chemical composition shall be as follows:
14.1.1.1 When samples are taken at the time the castings are
poured, at least one sample shall be taken for each group of
castings poured simultaneously from the same source of
molten metal.

X1. METRIC EQUIVALENTS
X1.1 The SI unit for strength properties now shown is in
accordance with the International System of Units (SI). The
derived SI unit for force is the newton (N), which is defined as
that force which when applied to a body having a mass of one
kilogram gives it an acceleration of one metre per second
squared (N = kg·m/s2). The derived SI unit for pressure or
stress is the newton per square metre (N/m2), which has been
named the pascal (Pa) by the General Conference on Weights
and Measures. Since 1 ksi = 6 894 757 Pa the metric equiva-
lents are expressed as megapascal (MPa), which is the same as
MN/m2 and N/mm2
