casing is galvanized (zinc coated) steel (see 3.3.1. 1),
the coating shall be smooth and tight, free from
pinholes, and of sufficient thickness to withstand
the corrosion test specified in 4.4.2.3. The coat-
ing shall not decrease the flexibility of the hose.
3.3.2 Core. - The flexible core shall consist of
several layers of helically wound, high strength,
steel wires, each layer wound in opposite direction
to the preceding layer. The number of wires in each
layer, the wire sizes and wire material may vary
between size of core and the manufacturer, The
core shall conform to table II.

transmitting the static torques of table IV for the
lengths indicated without permanent distortion or
rupture in both directions of rotation.
