GENERAL NOTES:(a) For P-Numbers, see QW/QB-422; for F-Numbers, see QW-432.(b) The dimensions of the test jig shall be such as to give the bend test specimen a calculated percent outer fiber elongation equal to at least that

of the base material with the lower minimum elongation as specified in the base material specification.

percent outer fiber elongation p100tA + t

The following formula is provided for convenience in calculating the bend specimen thickness:

thickness of specimen (t) pA � percent elongation

[100 − (percent elongation)]

(c) For guided-bend jig configuration, see QW-466.2, QW-466.3, and QW-466.4.(d) The weld and heat-affected zone, in the case of a transverse weld bend specimen, shall be completely within the bend portion of the specimen

after testing.(e) For materials with less than 3% elongation, a macro-etch specimen shall be used in lieu of bend test at each bend test location. Acceptance

criteria shall be in accordance with QW-183(a).

QW-466.2 GUIDED-BEND ROLLER JIG

Notes (1), (2)

Note (3)

Notes (4), (5)

GENERAL NOTE: See QW-466.1 for jig dimensions and general notes.

NOTES:(1) Either hardened and greased shoulders or hardened rollers free to rotate shall be used.(2) The shoulders or rollers shall have a minimum bearing surface of 2 in. (50 mm) for placement

of the specimen. The rollers shall be high enough above the bottom of the jig so that thespecimens will clear the rollers when the ram is in the low position.

(3) The ram shall be fitted with an appropriate base and provision made for attachment tothe testing machine, and shall be of a sufficiently rigid design to prevent deflection andmisalignment while making the bend test. The body of the ram may be less than the dimen-sions shown in column A of QW-466.1.

(4) If desired, either the rollers or the roller supports may be made adjustable in the horizontaldirection so that specimens of t thickness may be tested on the same jig.

(5) The roller supports shall be fitted with an appropriate base designed to safeguard againstdeflection and misalignment and equipped with means for maintaining the rollers centeredmidpoint and aligned with respect to the ram.

QW-466.3 GUIDED-BEND WRAP AROUND JIG

GENERAL NOTES: (a) See QW-466.1 for jig dimensions and other general notes.(b) Dimensions not shown are the option of the designer. The essential consideration is to have

adequate rigidity so that the jig parts will not spring.(c) The specimen shall be firmly clamped on one end so that there is no sliding of the specimen

during the bending operation.(d) Test specimens shall be removed from the jig when the outer roll has been removed 180 deg from the starting point.
