No 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:
- (1) Date of manufacture;
- (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.
