In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
6061 sheet in the T4 condition can be formed with limited ductility in the cold state. For deep draw and complex shapes, and for the avoidance of spring-back, an aluminium hot stamping process ( Hot Form Quench ) can be used, which forms a blank at a elevated temperature (~ 550 C) in a cooled die, leaving a part in W-temper condition before ...
A California car license plate saying ANRCHST (a vanity plate–speak form of anarchist) from 2006. The use of year-of-manufacture (YOM) plates is authorized by Section 5004.1 of the California Motor Vehicle Code. It is a law that allows vintage cars to be registered to use vintage license plates.

[1] [2] From 1980 to 2005, private and federal government insurers in the United States paid $320 billion in constant 2005 dollars in claims (or about $499 billion in ...
Automatic transmission fluid (ATF) is a hydraulic fluid that is essential for the proper functioning of vehicles equipped with automatic transmissions. Usually, it is coloured red or green to differentiate it from motor oil and other fluids in the vehicle. This fluid is designed to meet the unique demands of an automatic transmission.
R-12, the first automotive air conditioning refrigerant, was invented in 1928 by a team of scientists put together by Thomas Midgley, Jr. The team of scientists set out to create refrigerants which led to the invention of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). From these two inventions, two refrigerants were created, R ...
Standard state. The standard state of a material (pure substance, mixture or solution) is a reference point used to calculate its properties under different conditions. A degree sign (°) or a superscript Plimsoll symbol ( ⦵) is used to designate a thermodynamic quantity in the standard state, such as change in enthalpy (Δ H °), change in ...
