SAE
SAE International (SAE), formerly the Society of Automotive Engineers, is a professional organization for mobility engineering professionals in the aerospace, automotive, and commercial vehicle industries. The Society is a standards development organization for the engineering of powered vehicles of all kinds, including cars, trucks, boats, aircraft, and others. Membership is open to the public for those particularly interested in Human Factors and Ergonomic Standards.
SAE has established a number of standards used in the automotive industry and elsewhere. The standards most familiar to the average American consumer probably include:
* measuring automobile power in units of horsepower (SAE Net Horsepower), which has been generally followed in the USA since the early 1970s
* motor oil classification standards
* tool measurement sizes
* Modern vehicles are equipped with a diagnostic system known as On-Board Diagnostics II (OBD II). If a malfunction occurs, a Check Engine Light will alert the driver who must scan the system for stored fault codes. These fault codes are known as SAE Diagnostic Trouble Codes (DTCs).
All headlights used on North American roads must adhere to SAE standards to ensure driver safety.
ECE
The United Nations Economic Commission for Europe (UNECE or ECE) was established in 1947 to encourage economic cooperation among its member States. It is one of five regional commissions under the administrative direction of United Nations headquarters. It has 56 member States, and reports to the UN Economic and Social Council (ECOSOC). It is tasked with creating a uniform set of regulations for vehicle design to facilitate international trade.
The World Forum for Harmonization of Vehicle Regulations is a working party of the ECE. The forum works on regulations covering vehicle safety, environmental protection, energy efficiency and theft-resistance.
All headlights used on European roads must adhere to ECE standards to ensure driver safety.
