The WLTP replaces the old NEDC as the European homologation lab-bench procedure, which was established in the 1980s to simulate urban driving conditions for a passenger car. [8] In 1992 the NEDC was updated to also include a non-urban path (characterized by medium to high speeds), and finally in 1997 CO 2 emission figures were added, too. [ 9 ]
Motor vehicle type approval is the method by which motor vehicles, vehicle trailers and systems, components and separate technical units intended for such vehicles achieve type approval in the European Union (EU) or in other UN-ECE member states. There is no EU approval body: authorized approval bodies of member states are responsible for type ...
This resulted in the 1958 Agreement on uniform conditions of approval and mutual recognition of vehicle approvals, components, and parts. This was one of the first international agreements on vehicle regulation, which initially focused on European countries. The European Union played a role in harmonizing regulations between member states.
The European Commission intends to introduce a type approval procedure to measure the energy efficiency of mobile air conditioning systems in vehicles, as well as its effect on fuel consumption and emissions, and display an efficiency label on the vehicle; the work is being performed by TU Graz (Institute for Internal combustion engines and ...
Many vehicle codes created since the adoption of ISO 3166 coincide with ISO two- or three-letter codes. The 2004 South-East Asian Agreement ... for the Facilitation of Cross-Border Transport of Goods and People uses a mixture of ISO and DSIT codes: Myanmar uses MYA, China CHN, and Cambodia KH (ISO codes), Thailand uses T (DSIT code), Laos LAO ...

Generally, type approval is required before a product is allowed to be sold in a particular country, so the requirements for a given product will vary around the world.
Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.
