   CHAPTER I--PIPELINE AND HAZARDOUS MATERIALS SAFETY ADMINISTRATION, 
                      DEPARTMENT OF TRANSPORTATION
 
PART 180_CONTINUING QUALIFICATION AND MAINTENANCE OF PACKAGINGS--Table 
 
        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 exemption 
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; 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) Calibration 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 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, check), 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 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.
