hose assembly: a length of hose with a insert: optional term for nipple (see nipple).
coupling attached to one or each end.
inspection block: a description on a drawing
hose clamp: a collar, band or wire used to hold of the dimensional inspection to which a hose
hose on to a fitting, See also: clamp, ferrule. will be subjected.
hose duck: a woven fabric made from plied instantaneous modulus: the slope of a
yarns with approximately equal strength in stress-strain curve at a single point, employed
warp and filling directions. when modulus varies from point to point.
hot air cure: vulcanization by using heated air, interstice: a small opening, such as between
with or without pressure, See also: air cure, fibers in a cord or threads in a woven or braided
vulcanization. fabric.
hysteresis: a loss of energy due to successive intrinsic viscosity: the ratio of the difference
deformation and relaxation. It is measured by of the viscosity of the solution, at the given
the area between the deformation and relaxation concentration and the viscosity of the pure
stress-strain curves. solvent to the product of the viscosity of the
pure solvent and the volume concentration of
hysteresis loop: in general, the area between the solution.
stress-strain curves of increasing and reducing
stress; a measure of hysteresis. IPT: the abbreviation for standard iron pipe
thread.

Organization for Standardization.
identification yarn: a yarn of single or
multiple colors, usually embedded in the hose J
wall, used to identify the manufacturer. jacket: (1) a seamless tubular braided or
woven ply generally on the outside of a hose;
immediate set: the amount of deformation (2) a woven fabric used during vulcanization by
measured immediately after removal of the load
causing the deformation, the wrapped cure method.

impregnation: the act of filling the interstices
of an article with a rubber compound. Generally kinking: a temporary or permanent distortion
applies to the treatment of textile fabrics and of the hose induced by bending beyond the
cords. minimum bend radius.
impression: a design formed during knit fabric: a flat or tubular structure made
vulcanization in the surface of a hose by a from one or more yarns or filaments whose
method of transfer, such as fabric impression or direction is generally transverse to the fabric
molded impression, axis but whose successive passes are united by
a series of interlocking loops.
impression, fabric: impression formed on the
rubber surface during vulcanization by contact knit ply: a layer of textile reinforcement in
with fabric jacket or wrapper, which the yarns are applied in an interlocking
looped configuration in a continuous tubular
impulse: an application of force in a manner to
produce sudden strain or motion, such as structure.
hydraulic pressure applied in a hose. knitter: a machine for forming a fabric by the
action of needles engaging threads in such a
indentation: (1) the extent of deformation by
the indentor point of any one of a number of manner as to cause a sequence of interlaced
loops (Interlaced loops forming a continuous
standard hardness testing instruments; (2) a
recess in the surface of a hose. tubular structure are commonly used as hose
reinforcement).
inhibitor: an ingredient used to suppress a
chemical reaction or a growing activity such as
mildew.
