In Title 49 of the Code of Federal Regulations, Parts 178 to 199, 
revised as of October 1, 2012, in Sec.  178.68, on page 80, paragraph 
(i)(2) is correctly reinstated and on page 81, paragraph (l)(2) is 
revised to read as follows:


Sec.  178.68  Specification 4E welded aluminum cylinders.

* * * * *
    (i) * * *
    (2) If the weld is at midlength of the cylinder, the test may be 
made as specified in paragraph (i)(1) of this section or must be made 
between wedge shaped knife edges (60[deg] angle) rounded to a \1/2\ 
inch radius. There must be no evidence of cracking in the sample when 
it is flattened to no more than 6 times the wall thickness.
* * * * *
    (l) * * *
    (2) Guided bend test. A bend test specimen must be cut from the 
cylinder used for the physical test specified in paragraph (j) of this 
section. Specimen must be taken across the seam, must be a minimum of 
1\1/2\ inches wide, edges must be parallel and rounded with a file, and 
back-up strip, if used, must be removed by machining. The specimen 
shall be tested as follows:
    (i) The specimen must be bent to refusal in the guided bend test 
jig as illustrated in paragraph 6.10 of CGA C-3 (IBR, see Sec.  171.7 
of this subchapter). The root of the weld (inside surface of the 
cylinder) must be located away from the ram of the jig. The specimen 
must not show a crack or other open defect exceeding \1/8\ inch in any 
direction upon completion of the test. Should this specimen fail to 
meet the requirements, specimens may be taken from each of 2 additional 
cylinders from the same lot and tested. If either of the latter 
specimens fails to meet requirements, the entire lot represented must 
be rejected.
    (ii) Alternatively, the specimen may be tested in a guided bend 
test jig as illustrated in Figure 12.1 of The Aluminum Association's 
2002 publication, ``Welding Aluminum: Theory and Practice.'' The root 
of the weld (inside surface of the cylinder) must be located away from 
the mandrel of the jig. No specimen must show a crack or other open 
defect exceeding \1/8\ inch in any direction upon completion of the 
test. Should this specimen fail to meet the requirements, specimens may 
be taken from each of 2 additional cylinders from the same lot and 
tested. If either of the latter specimens fails to meet requirements, 
the entire lot represented must be rejected.
