制定人体暴露于0至3kHz电磁场的安全等级。本标准将基于对相关科学文献的评估结果和已证实的效应，这些效应已得到充分证实，且反应阈值已被理解。磁场极限将由阈值电流密度或内部电场得出。

Develop safety levels for human exposure to electromagnetic fields from 0 to 3kHz. This standard will be based on the results of an evaluation of the relevant scientific literature and proven effects which are well established and for which thresholds of reaction are understood. Field limits will be derived from threshold current densities or internal electric fields.
