CHAPTER I--RESEARCH AND SPECIAL PROGRAMS ADMINISTRATION, DEPARTMENT OF
TRANSPORTATION
PART 180--CONTINUING QUALIFICATION AND MAINTENANCE OF PACKAGINGS
--Table of Contents
Subpart C--Qualification, Maintenance and Use of Cylinders
Sec. 180.215 Reporting and record retention requirements.
(a) Facility records. A person who requalifies, repairs or rebuilds
cylinders must maintain the following records where the requalification
is performed:
(1) Current RIN issuance letter;
(2) If the RIN has expired and renewal is pending, a copy of the
renewal request;
(3) Copies of notifications to Associate Administrator required
under Sec. 107.805 of this chapter;
(4) Current copies of those portions of this subchapter applicable
to its cylinder requalification and marking activities at that location;
(5) Current copies of all special permits governing special permit cylinders
requalified or marked by the requalifier at that location; and
(6) The information contained in each applicable CGA or ASTM
standard incorporated by reference in Sec. 171.7 of this subchapter
applicable to the requalifier's activities. This information must be the
same as contained in the edition incorporated by reference in Sec. 171.7
of this subchapter.
(b) Requalification records. Daily records of visual inspection,
pressure test, and ultrasonic examination if permitted under a special permit, as applicable, must be maintained by the person who performs
the requalification until either the expiration of the requalification
period or until the cylinder is again requalified, whichever occurs
first. A single date may be used for each test sheet, provided each test
on the sheet was conducted on that date. Ditto marks or a solid vertical
line may be used to indicate repetition of the preceding entry for the
following entries only: date; actual dimensions; manufacturer's name or
symbol, if present; owner's name or symbol, if present; and test
operator. Blank spaces may not be used to indicate repetition of a prior
entry. The records must include the following information:
(1) Pressure test records. For each test to demonstrate calibration,
the date; serial number of the calibrated cylinder; calibration test
pressure; total, elastic and permanent expansions; and legible
identification of test operator. The test operator must be able to
demonstrate that the results of the daily calibration verification
correspond to the hydrostatic tests performed on that day. The daily
verification of calibration(s) may be recorded on the same sheets as,
and with, test records for that date.
(2) Pressure test and visual inspection records. The date of
requalification; serial number; DOT specification or special permit number;
marked pressure; actual dimensions; manufacturer's name or symbol;
owner's name or symbol, if present; result of visual inspection; actual
test pressure; total, elastic and
[[Page 1059]]
permanent expansions; percent permanent expansion; disposition, with
reason for any repeated test, rejection or condemnation; and legible
identification of test operator. For each cylinder marked pursuant to
Sec. 173.302a(b)(5) of this subchapter, the test sheet must indicate the
method by which any average or maximum wall stress was computed. Records
must be kept for all completed, as well as unsuccessful tests. The entry
for a second test after a failure to hold test pressure must indicate
the date of the earlier test.
(3) Wall stress. Calculations of average and maximum wall stress
pursuant to Sec. 173.302a(b)(3) of this subchapter, if performed.
(4) Calibration certificates. The most recent certificate of
calibration must be maintained for each calibrated cylinder.
(c) Repair, rebuilding or reheat treatment records. (1) Records
covering welding or brazing repairs, rebuilding or reheat treating shall
be retained for a minimum of fifteen years by the approved facility.
(2) A record of rebuilding, in accordance with Sec. 180.211(d), must
be completed for each cylinder rebuilt. The record must be clear,
legible, and contain the following information:
(i) Name and address of test facility, date of test report, and name
of original manufacturer;
(ii) Marks stamped on cylinder to include specification number,
service pressure, serial number, symbol of manufacturer, inspector's
mark, and other marks, if any;
(iii) Cylinder outside diameter and length in inches;
(iv) Rebuild process (welded, brazed, type seams, etc.);
(v) Description of assembly and any attachments replaced (e.g.,
neckrings, footrings);
(vi) Chemical analysis of material for the cylinder, including seat
and Code No., type of analysis (ladle, checKB), chemical components
(Carbon (C), Phosphorous (P), Sulfur (S), Silicon (Si), Manganese (Mn),
Nickel (Ni), Chromium (Cr), Molybdenum (Mo), Copper (Cu), Aluminum (Al),
Zinc (Zn)), material manufacturer, name of person performing the
analysis, results of physical tests of material for cylinder (yield
strength (psi), tensile strength (psi), elongation percentage (inches),
reduction in area percentage, weld bend, tensile bend, name of
inspector);
(vii) Results of proof pressure test on cylinder, including test
method, test pressure, total expansion, permanent expansion, elastic
expansion, percent permanent expansion (permanent expansion may not
exceed ten percent (10%) of total expansion), and volumetric capacity
(volumetric capacity of a rebuilt cylinder must be within <plus-minus>
3% of the calculated capacity);
(viii) Each report must include the following certification
statement: ``I certify that this rebuilt cylinder is accurately
represented by the data above and conforms to all of the requirements in
Subchapter C of Chapter I of Title 49 of the Code of Federal
Regulations.''. The certification must be signed by the rebuild
technician and principal, officer, or partner of the rebuild facility.
