本标准规定了暴露标准和限值，以防止暴露在频率范围为0 Hz至300 GHz的电场、磁场和电磁场中对人体造成不良健康影响。1.2这些限值，包括安全裕度，用剂量学参考限值（DRL）和暴露参考水平（ERL）表示。DRL用原位电场强度、比吸收率（SAR）和上皮细胞功率密度表示。ERL更容易确定，它是对外部电场和磁场、入射功率密度、感应电流和接触电流以及接触电压的限制，旨在确保不超过DRL。这些限制可以防止与组织、局部和整体电刺激相关的不良健康影响- 身体加热适用于所述的人体暴露条件。然而，这些水平并不是为了解决在医疗专业人员照管下的患者或人体研究受试者的暴露问题，其他风险和益处可能适用。这些接触限值可能无法防止对可能易受电磁干扰（EMI）影响的医疗设备和其他设备的干扰。

This standard specifies exposure criteria and limits to protect against established adverse health effects in humans associated with exposure to electric, magnetic, and electromagnetic fields in the frequency range of 0 Hz to 300 GHz.1,2 These limits, incorporating safety margins, are expressed in terms of dosimetric reference limits (DRL) and exposure reference levels (ERL). DRLs are expressed in terms of in situ electric field strength, specific absorption rate (SAR), and epithelial power density. ERLs, which are more easily determined, are limits on external electric and magnetic fields, incident power density, induced and contact currents, and contact voltages intended to ensure that the DRLs are not exceeded. The limits, which protect against adverse health effects associated with electrostimulation of tissue and local and whole-body heating, are intended to apply to the described human exposure conditions. However, these levels are not intended to address exposures of patients or human research subjects under the care of medical professionals for which other risks and benefits might apply. These exposure limits might not prevent interference with medical and other devices that might exhibit susceptibility to electromagnetic interference (EMI).
