本SAE标准涵盖射频辐射发射和抗扰度的测量。每个部分详细说明了特定类型电磁兼容性（EMC）测试的要求以及测试方法的适用频率范围。这些方法适用于由内燃机或电池驱动的电动机驱动的车辆、船只、机器或装置。包括车辆、船只、机器或装置的所有发动机或电机（主发动机和辅助发动机）的操作。包括车辆、船只、机器或装置运行时正常运行的所有设备。 操作员控制设备包括或不包括在单独文件部分中规定的范围内。作为特例，CISPR 12适用于电池供电的地板修整设备，但不包括机器人地毯清扫器。通过参考，采用IEC CISPR 12和CISPR 25作为车辆排放测量标准。如果进行了修订或发布了新版IEC文件，新IEC文件应在IEC文件发布六个月后成为本标准的一部分。SAE保留识别已发布IEC文件的例外情况的权利，例外情况将记录在SAE J551中- 2和SAE J551-4。同样通过引用，ISO 11451-2、ISO 11451-3和ISO 11451-4被用作车辆抗扰度测量的标准。如果进行了修订或发布了新版，新的ISO文件应在ISO文件发布六个月后成为本标准的一部分。SAE保留识别已发布ISO文件的例外情况的权利，例外情况将分别记录在SAE J551-11、SAE J551-12和SAE J551-13中。建议的水平仅适用于最终制造形式的整车。 当在充电模式下运行时，用于电动汽车充电的车载整流器包含在本系列文件中。本文件不控制有意散热器的排放。（参见适用的、适当的监管文件。）本文件不包括商用市电供电设备对过电压和线路瞬变的抗扰度。

This SAE Standard covers the measurement of radio frequency radiated emissions and immunity. Each part details the requirements for a specific type of electromagnetic compatibility (EMC) test and the applicable frequency range of the test method.The methods are applicable to a vehicle, boat, machine or device powered by an internal combustion engine or battery powered electric motor. Operation of all engines or motors (main and auxiliary) of a vehicle, boat, machine or device is included. All equipment normally operating when the vehicle, boat, machine or device is in operation is included. Operator controlled equipment is included or excluded as specified in the individual document parts.As a special case, CISPR 12 applies to battery powered floor finishing equipment, but robot carpet sweepers are excluded. By reference, IEC CISPR 12 and CISPR 25 are adopted as the standards for the measurement of vehicle emissions. In the event that an amendment is made or a new edition is published, the new IEC document shall become part of this standard six months after the publication of the IEC document. SAE reserves the right to identify exceptions to the published IEC documents with the exceptions to be documented in SAE J551-2 and SAE J551-4, respectively. Also by reference, ISO 11451-2, ISO 11451-3 and ISO 11451-4 are adopted as standards for the measurement of vehicle immunity. In the event that an amendment is made or a new edition is published, the new ISO document shall become part of this standard six months after the publication of the ISO document. SAE reserves the right to identify exceptions to the published ISO documents with the exceptions to be documented in SAE J551-11, SAE J551-12 and SAE J551-13, respectively.The recommended levels apply only to complete vehicles in their final manufactured form. Vehicle-mounted rectifiers used for charging in electric vehicles are included in this series of documents when operated in their charging mode.Emissions from intentional radiators are not controlled by this document. (See applicable, appropriate regulatory documents.) The immunity of commercial mains powered equipment to over voltages and line transients is not covered by this document.
