- abandonment
-
- The act of a transporting company (bus, courier, railway, ship, etc.) in which it will no longer service a previously serviced route. In some cases abandonment must be approved by the ICC
- The act of a shipper or consignee who refuses to accept delivery
- The act of relinquishing title to damaged or lost property by claiming a total loss.

- AB-screw
- A screw used in sheet metal but rarely in stainless steel.
- The AB designation is made because it has a pointed end similar to a type-A screw and thread dimensions similar to a type-B screw.
- ABC
-
- Acronym for aerial bunched conductors
- Acronym for automatic beam control.
- ABC Classification
- An inventory classification system
- A system for classifying inventory or parts within a warehouse where fast moving products are designated as "A" items, while "B" and "C" items are not as fast moving.
- In some warehouses, however, "A" items are those with the best profit margins.
- ABDC
- Acronym for after bottom dead center.
- A term used in timing the relation of the spark and the crankshaft
- measured in degrees of rotation.
- Abel flashpoint apparatus
- A device for testing the flash point of gasoline.

- Acronym for air bypass valve.
- abrasive
-
- A hard grit used for sanding or grinding.
- Usually a powder e.g., silicon carbide powder.
- Materials such as sand or chipped rock that are spread on paved roads to
increase vehicle traction.
- Also called aggregates
- A hard grit used for sanding or grinding.
- abrasive blast cleaning
-
A process of cleaning with gusts of fine particles
- In order to clean steel or remove rust from iron or scale from metal, sand or some other powder substance is forced by air pressure through a nozzle.
- In this way the small particles of abrasive can penetrate the metal where sanding with sandpaper cannot.
- Also, very small craters are formed on the surface of the metal from the blasting action.
- When thoroughly cleaned the metal is ready for painting.
- Paint adheres better to these craters and imperfections than to a perfectly smooth surface.
- abrasive cleaner
-
A cleaning paste with some hard grit.
- It is used to remove the grime and oils from a surface or from your hands.
- abrasive disc
-
A circular plate (often made of plastic with hard grit embedded into it) used for grinding or sanding.
abrasive disc
- abrasive paper
- Sandpaper (a paper upon which sand or hard grit has been glued) used for sanding or grinding.
- ABS
-
Acronym for anti-lock brake system.
- The acronym ABS comes from the German anti blockier system.
- A computer, sensors, and solenoid valves work together to sense wheel speed in order to modulate braking force if wheels lockup during braking.
- ABS can help the driver retain control of the vehicle during heavy braking on slippery roads.
- It works on the principle of braking a wheel until it just begins to skid (this is the point where braking efficiency would drop off dramatically) and then releasing the brake pressure and re-applying the brakes.
- Wheel speed sensors identify the skid point and trigger a release in brake pressure.
- The cycle is repeated many times a second.
- The driver will feel a rapid pulsing at the brake pedal and hear a chattering noise as ABS is applied.
- Absolute ampere
- The metric standard unit of electric current which replaced the international unit in 1948
- Absolute humidity
- The ratio of the mass of water vapor in a sample of moist air to the volume of the sample.
- Absolute Liability
- The shipping carrier assumes responsibility for all damages and for late shipment, etc. and is not protected by normal exemptions found in a bill of lading or common law liability.
- Absolute pressure
-
- Pressure measured from a starting point of zero in perfect vacuum.
- When measured by the absolute pressure scale, atmospheric pressure is 14.7 psi or 29.92 inches of mercury (in-Hg).
- Total pressure equal to gauge pressure plus 14.7 lbs./sq. in. at sea level.
- Pressure measured from a starting point of zero in perfect vacuum.
- Absolute temperature
-
The temperature above absolute zero
- The temperature plus 273°C.
- absorbent
-
A substance with the property of assimilating another substance (e.g., sponge
and water).
