55-Gallon Open-Head Steel Drum to ICC Specification 17H (1964)
The open-top 55-gallon (208-litre) steel drum, built to the rule US railways and shippers used for single-trip removable-head drums: welded low-carbon steel body, three rolled hoops, a crowned bottom, and a lid clamped by a bolted ring over a gasket.
Source: ICC Specification 17H, 49 CFR 78.118, Federal Register, 29 December 1964. The spec does not say how the bottom is joined. The litre figure, the gasket rubber and the machines are ours. Picture drawn by Youblob.
