(II) Steel pipe of unknown or unlisted specification.
(II) (A) Bending properties.
For pipe 2 inches (51 millimeters) or less in diameter, a
				length of pipe must be cold bent through at least 90 degrees around a
				cylindrical mandrel that has a diameter 12 times the diameter of the pipe,
				without developing cracks at any portion and without opening the longitudinal
				weld.
For pipe more than 2 inches (51 millimeters) in diameter, the
				pipe must meet the requirements of the flattening tests set forth in ASTM
				Specification A53/A53M (as described in section
				10.3  of this Title), except that
				the number of tests must be at least equal to the minimum required in paragraph
				II-D of this Appendix to determine yield strength. .......
(II) (B) Weldability. A girth weld must be made in the pipe by
				a welder who is qualified under this Part. The weld must be made under the most
				severe conditions under which welding will be allowed in the field and by means
				of the same procedure that will be used in the field. On pipe more than 4
				inches (102 millimeters) in diameter, at least one test weld must be made for
				each 100 lengths of pipe. On pipe 4 inches (102 millimeters) or less in
				diameter, at least one test weld must be made for each 400 lengths of pipe. The
				weld must be tested in accordance with API Standard 1104 (as described in
				section 10.3  of this Title). If the
				requirements of API Standard 1104 (as described in section
				10.3  of this Title) cannot be met,
				weldability may be established by making chemical tests for carbon and
				manganese, and proceeding in accordance with section IX of the ASME Boiler and
				Pressure Vessel Code. The same number of chemical tests must be made as are
				required for testing girth weld.
(II) (C) Inspection. The pipe must be clean enough to permit
				adequate inspection. It must be visually inspected to ensure that it is
				reasonably round and straight and there are no defects which might impair the
				strength or tightness of the pipe.
(II) (D) Tensile properties. If the tensile properties of the
				pipe are not known, the minimum yield strength may be taken as 24,000 psi (165
				MPa) or less, or the tensile properties may be established by performing
				tensile tests as set forth in API Specification 5L. All test specimens shall be
				selected at random and the following number of tests must be performed:
Number of Tensile Tests-All
				Sizes
10 lengths or less .......
1 set of tests for each length.
11 to 100 lengths .......
1 set of tests for each 5 lengths, but not less than 10
						  tests.
Over 100 lengths .......
1 set of tests for each 10 lengths, but not less than 20
						  tests.
If the yield-tensile ratio, based on the properties determined
				by those tests, exceeds 0.85, the pipe may be used only as provided in section
				255.55(c)  of this
				Title.
(III) Steel pipe manufactured before November 12, 1970, to
				earlier editions of listed specifications. Steel pipe manufactured before
				November 12, 1970, in accordance with a specification of which a later edition
				is listed in section I of this Appendix, is qualified for use under this Part
				if the following requirements are met:
(III) (A) Inspection. The pipe must be clean enough to permit
				adequate inspection. It must be visually inspected to ensure that it is
				reasonably round and straight and that there are no defects which might impair
				the strength or tightness of the pipe.
(III) (B) Similarity of specification requirements. The edition
				of the listed specification under which the pipe was manufactured must have
				substantially the same requirements with respect to the following properties as
				a later edition of that specification listed in section I of this
				appendix:
(III) (1) Physical (mechanical) properties of pipe, including
				yield and tensile strength, elongation, and yield to tensile ratio, and testing
				requirements to verify those properties.
(III) (2) Chemical properties of pipe and testing requirements
				to verify those properties.
(III) (C) Inspection or test of welded pipe. On pipe with
				welded seams, one of the following requirements must be met:
(III) (1) The edition of the listed specification to which the
				pipe was manufactured must have substantially the same requirements with
				respect to nondestructive inspection of welded seams and the standards for
				acceptance or rejection and repair as a later edition of the specification
				listed in section I of this Appendix.
(III) (2) The pipe must be tested in accordance with this Part
				to at least 1.25 times the maximum allowable operating pressure if it is to be
				installed in a class 1 location and to at least 1.5 times the maximum allowable
				operating pressure if it is to be installed in a class 2, 3, or 4 location.
				Notwithstanding any shorter time period permitted under this Part, the test
				pressure must be maintained for at least 8 hours.
