Explanatory Notes:

1. Type Approval (TA)
Most countries require some form of certification or type approval by vehicle manufacturer to demonstrate that each new vehicle sold is capable of meeting the countries applicable emission standards. Usually, type approval requires testing of prototype vehicles representative of planned mass production vehicles. Under European Community and Japanese regulations, such compliance is required only for new vehicles. US regulations require that the vehicles comply with emission standards throughout their useful lives when maintained according to the manufacturing specifications. The advantage of a certification or type approval programs is that it can influence vehicle design prior to mass production. It is more cost effective because the manufacturers identify and correct the problems before production actually begins.

2. Approval of a Vehicle
Vehicle manufacturers apply for approval of a vehicle type with regard to exhaust emissions, evaporative emissions and durability of pollution control devices to the authority responsible for conducting the tests. The application of approval also includes details like description of engines type comprising all the particulars, drawings of the combustion chamber and of the piston, description of evaporative control system, particulars concerning the vehicles, description of pollution control devices, etc. If the vehicle type submitted for approval meets the requirements of various types of tests mentioned, only then the approval of that vehicle is granted.

3. Conformity of Production
The conformity of production is an assembly line testing system. The objectives of assembly line testing are to enable regulatory authorities to identify certified production vehicles that do not comply with applicable emission standards, to take remedial actions (such as revoking certification and recalling vehicles) to correct the problem, and to discourage the manufacture of non-complying vehicles.
This test provides an additional check on mass-produced vehicles to assure that the designs found adequate in certification are satisfactorily translated into production, and that quality control on the assembly line is sufficient to provide reasonable assurance that vehicles in use meet standards. The basic difference between Type Approval and Conformity of Production is based on prototype vehicle or design of the vehicle while Conformity of Production measures emissions from real production vehicles.
