Also known as an impact gun, air wrench, air gun, or rattle gun; a powered tool that supplies high torque to
turn a socket
inrush current
Also known as input surge current or switch-on surge; the maximum instantaneous current that a motor uses
when it is first turned on
ISO
International Organization for Standardization, an independent membership organization that develops
voluntary industrial standards
JIC
Joint Industry Council, a type of hydraulic flare fitting used for connections in high-pressure fluid systems
The fitting is composed of a fitting, a flare nut, and a sleeve.
joule
A unit that identifies the work or energy transferred when applying a force of 1 newton to an object through a
distance of 1 meter: 1 joule equals 1 N∙m or 0.746 ft∙lbf.
Refer to
ft∙lbf.
kPa
Kilopascal, a unit of pressure: 1 kPa equals 0.01 bar or 0.15 psi or 1,000 N/m
2
lap
To use lapping film on a stainless-steel surface to make the surface very smooth and flat
lbf∙ft
Pound force foot, the torque made when applying a force of 1 pound at a 1-foot distance from a
perpendicular pivot point: 1 lbf∙ft equals 12 lbf∙in or 1.36 N∙m
lbf∙in
Pound force inch, the torque made when applying a force of 1 pound at a 1-inch distance from a
perpendicular pivot point: 1 lbf∙in equals 0.0833 lbf∙ft or 0.113 N∙m
lock out
Refers to practices and procedures that protect personnel from the starting of machinery or equipment, or
the release of dangerous energy during maintenance or repair work
Lock-out devices hold energy-isolation devices in a safe or off position and can not be removed without a key
or other unlocking mechanism or through special means, such as bolt cutters.
low-pressure water (CUTTING WATER IN)
Low-pressure water from a water softener, a reverse osmosis system, a well, or a public utility that is between
the utility panel and the intensifier
Refer to
prefilter water and postfilter water.
N/m
2
Newtons per square meter, a unit of pressure: 1 N/m
2
equals 0.00001 bar or 0.001 kPa or 0.00015 psi
NFPA 70
