NOTE 1—Testing at a pressure greater than 1000 psi may be performed upon agreement between purchaser and manufacturer provided that the
allowable fiber stress is not exceeded.
5.2.2 If any pipe or tube shows leaks during hydrostatic testing, it shall be rejected.
5.3 Nondestructive Electric Test:
5.3.1 Eddy Current Testing—Testing shall be conducted in accordance with Practices E426 or E571. The eddy current
examination reference in this specification has the capability of detecting significant discontinuities, especially of the short, abrupt
type.
5.3.1.1 Unless otherwise specified by the purchaser, the calibration standard shall contain, at the option of the manufacturer, any
one of the following discontinuities to establish a minimum sensitivity level for rejection.
5.3.1.2 Drill Hole—A hole not larger than 0.031 in. (0.79 mm) diameter shall be drilled radially and completely through the
wall, care being taken to avoid distortion of the material while drilling.
5.3.1.3 Transverse Tangential Notch—Using a round file or tool with a ⁄4 in. (6 mm) diameter, a notch shall be filed or milled

5.3.2 Ultrasonic Testing—Testing shall be conducted in accordance with Practice E213. The ultrasonic examination referred to
in this specification is intended to detect longitudinal discontinuities having a reflective area similar to or larger than the calibration
reference notches specified in 5.3.2.1. The examination may not detect circumferentially oriented imperfections or short, deep
defects.
5.3.2.1 For ultrasonic testing, longitudinal calibration notches shall be machined on the outside and inside diameter surfaces.
The depth of the notches shall not exceed 12.5 % of the specified wall thickness or 0.004 in. (0.10 mm), whichever is greater.

5.3.3.2 At least every four hours during testing.
5.3.3.3 At the end of each production run or lot.
5.3.3.4 After any suspected equipment malfunction or work stoppage.
5.3.3.5 If, during any check, the equipment fails to detect the calibration defects, the instrument must be recalibrated and all
material tested since the last satisfactory check shall be retested.
5.3.4 Acceptance and Rejection—Material producing a signal equal to or greater than the calibration defect shall be subject to
rejection.
5.3.4.1 Test signals produced by imperfections that cannot be identified or produced by cracks or crack-like imperfections shall
result in rejection of the pipe or tube, subject to rework and retest.
5.3.4.2 If the imperfection is judged as not fit for use, the tube shall be rejected, but may be reconditioned and retested providing
the wall thickness requirements are met. To be accepted, retested material shall meet the original electric test requirements.
5.3.4.3 If the imperfection is explored to the extent that it can be identified, and the pipe or tube is determined to be fit for use,
the material may be accepted without further testing, providing the imperfection does not encroach on minimum wall thickness
requirements.
5.4 When specified by the purchaser, a nondestructive electric test, in accordance with Practices E213, E426, or E571, may be
used for seamless pipe or tube, instead of the hydrostatic test.
5.5 Tension Test—Tension testing shall be conducted in accordance with Test Methods E8/E8M.
5.5.1 The material shall conform to the tensile properties prescribed in the individual product specification.
B829 − 04a (2017)
5.6 Hardness Test—Hardness testing shall be conducted in accordance with Test Methods E18.
5.7 Grain Size—The measurement of average grain size may be carried out by the planimetric method, the comparison method,
or the intercept method described in Test Methods E112. In case of dispute, the “referee” method for determining average grain
size shall be the intercept method.
5.8 For purposes of determining compliance with the specified limits for requirements of the properties listed in the following
table, an observed value or a calculated value shall be rounded in accordance with the rounding method of Practice E29:
Rounded Unit for Observed
Requirements
or Calculated Value
Chemical composition and nearest unit in the last right-hand place
tolerances of figures of the specified limit
Tensile strength and yield strength nearest 1000 psi (7 MPa)
Elongation nearest 1 %
Grain size
0.0024 in. (0.060 mm) or larger nearest multiple of 0.0002 in. (0.005 mm)
Less than 0.0024 in. (0.060 mm) nearest multiple of 0.0001 in. (0.002 mm)
6. Dimensions and Permissible Variations
6.1 Dimensions of pipe are shown in Table 1.
6.1.1 Permissible variations in outside diameter and wall thickness are shown in Table 2, Table 3, and Table 4.
6.2 Length—When material is ordered as cut-to-length, the length shall conform to the permissible variations prescribed in
Table 5. When material is ordered to random lengths, the lengths and variations shall be agreed upon between the manufacturer
and purchaser.
6.3 Straightness—Material shall be reasonably straight and free of bends and kinks.
6.4 Ends—Ends shall be plain cut and deburred.
7. Workmanship, Finish, and Appearance
7.1 The material shall be uniform in quality and temper, smooth, and free from imperfections that would render it unfit for use.
