The load index on a passenger-car tire is a numerical code stipulating the maximum load (mass, or weight) each tire can carry. For load range "B" tires, ETRTO (ISO-Metric) standards specify the load index rating at an inflation pressure of 36 psi (250 kPa) (table below), while P-Metric standards measure the load capacity at an inflation ...
UTQG ratings (top) and tire code (bottom) on sidewall of Continental ContiProContact tire. Uniform Tire Quality Grading, commonly abbreviated as UTQG, is a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction. The UTQG was created by the National Highway Traffic Safety Administration in ...
Cold inflation pressure is the inflation pressure of tires before a car is driven and the tires (tyres) warmed up. Recommended cold inflation pressure is displayed on the owner's manual and on the placard (or sticker) attached to the vehicle door edge, pillar, glovebox door or fuel filler flap. Most passenger cars are recommended to have a tire ...
Production car tires typically develop this maximum lateral force, or cornering force, at a slip angle of 6-10 degrees, although this angle increases as the vertical load on the tire increases. [ 1 ] Formula 1 car tires may reach a peak side force at 3 degrees [ 2 ]
Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation , lateral force variation , conicity, ply steer, radial run-out , lateral run-out , and ...
NHTSA established the Uniform Tire Quality Grading System , is a system for comparing the performance of tires according to the Code of Federal Regulations 49 CFR 575.104; it requires labeling of tires for tread wear, traction, and temperature. The DOT Code is an alphanumeric character sequence molded into the sidewall of the tire and allows ...
Ohmic load and operating temperature often jointly determine a battery's discharge rate. [12] Moreover, if the expected operating temperature for a primary battery deviates from the typical 10 °C to 25 °C (50 to 77 °F) range, then operating temperature "will often have an influence on the type of battery selected for the application".

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 ...
