Product Code:SAE J2402
Title:Road Vehicles-Symbols for Controls, Indicators, and Tell-Tales
Issuing Committee:Controls And Displays Standards Committee
Scope:This SAE Standard establishes the symbols, i.e., conventional signs, for use of controls, indicators, and tell-tales of a road vehicle to ensure idnetification and facilitate use.It als indicates the colors of possible optical tell-tales which inform the driver of either correct operation or malfunctioning of the related devices.【英文标准名称】:Guidetoelectromagneticenvironmentforlow-frequencyconducteddisturbancesandsignallinginpublicpowersupplysystems
