Section 153.940 - Standards for marking of cargo hoseNo person may mark a hose assembly as meeting the standards of this section unless the hose assembly meets the following requirements:
(a) Each hose assembly must have:(1) Fully threaded connections;(2) Flanges that meet ANSI B16.5, B16.24, or B16.31; or(3) Class 1 quick-disconnect couplings that comply with ASTM F 1122 (incorporated by reference, see § 153.4 ), and are marked "C1-1."(b) Each hose assembly must be marked with the:(2) Working pressure described in paragraph (d) of this section;(3) Date of the last test made as prescribed in paragraph (e) of this section; and(4) Manufacturer's recommended maximum and minimum temperatures.(c) A cargo hose assembly must have a minimum bursting pressure as stated by the manufacturer of at least 5152 kPa gauge (approx. 750 psig).(d) The working pressure marked on a hose must meet the following:(1) Be at least 1030 kPa gauge (approx. 150 psig).(2) Not exceeded 20 per cent (one-fifth) of the manufacturer's stated bursting pressure.(3) Not exceed the manufacturer's recommended working pressure.(4) Not exceed the test pressure used in the latest test under paragraph (e)(3) of this section.(e) A cargo hose assembly must be inspected and tested by placing it in a straight, horizontal position so that its entire external surface is accessible. It must be ascertained that the hose assembly: (1) Has no loose covers, kinks, bulges, soft spots, and no gouges, cuts, or slashes that penetrate any hose reinforcement;(2) Has no external and, to the extent internal inspection is possible with both ends of the hose open, no internal deterioration; and(3) Does not burst, bulge, leak, or abnormally distort under static liquid pressure at least as great as the recommended working pressure.CGD 73-96, 42 FR 49027, Sept. 26, 1977, as amended by CGD 78-128, 47 FR 21211, May 17, 1982; CGD 88-032, 56 FR 35827, July 29, 1991; USCG-2000-7790, 65 FR 58463, Sept. 29, 2000; USCG-2014-0688, 79 FR 58284, Sept. 29, 2014
