工业、科学和医疗设备——无线电频率干扰特性——射频束无线功率传输(RB-WPT)设备的要求

[中文适用范围]： CISPR PAS 38:2025 是一项公开可用的规范，适用于无线电波束无线功率传输 (RB-WPT)，作为工作频率范围为 0 Hz 至 400 GHz 的工业、科学和医疗设备，其设计工作距离可达 10 米。本文件涵盖与 150 kHz 至 18 GHz 频率范围内射频干扰相关的发射要求。无线电波束无线功率传输设备仅在其未被归类为无线电设备时才属于本文件的范畴。注 1：在大多数国家/地区，使用调制信号传输功率和信息的无线电波束无线功率传输设备被归类为无线电设备。虽然无线电波束无线功率传输设备也包含在本文件的范围内，但即使传输的信号是连续波且未经调制，在某些国家/地区也可能被归类为无线电设备。建议用户在将本文件应用于此类设备之前，先核实适用的国家无线电法规，尤其是关于 ISM 频段内适用的限制，而本文件允许在该频段内进行无限制辐射。注2：无线电波束无线功率传输设备会产生大量的电磁能量。虽然本文件未包含射频 (RF) 暴露要求，但用户应采取适当措施，确保测试人员和其他旁观者不会受到受测产品产生的有害射频暴露。本 PAS 采纳了 CISPR 11 的要求，并对 CISPR 11 在 RB-WPT 中的应用提供了重要说明。 [外文原描述]： CISPR PAS 38:2025, which is a Publicly Available Specification, applies to radio beam wireless power transfer (RB‑WPT) as industrial, scientific, and medical equipment operating in the frequency range of 0 Hz to 400 GHz and designed to operate up to a distance of 10 m. This document covers emission requirements related to radio-frequency disturbances in the frequency range of 150 kHz to 18 GHz. Radio beam wireless power transfer devices are in the scope of this document only if they are not classified as radio apparatus. NOTE 1 Wireless power transfer devices that use a modulated signal to transmit both power and information are classified as radio apparatus in most countries. While radio beam wireless power transfer devices are included in the scope of this document, these can be classified as radio apparatus in some countries, even if the transmitted signal is continuous wave, with no modulation. The user is advised to verify the applicable national radio regulations before applying this document for these types of devices, especially regarding to limits applicable within the ISM bands wherein this document allows unrestricted radiation. NOTE 2 Radio beam wireless power transfer devices can generate significant electromagnetic energy. While this document does not include requirements for radio-frequency (RF) exposure, the user is warned to take appropriate measures to ensure testing personnel and other bystanders are not subjected to harmful levels of RF exposure from the product under test. This PAS adopts the requirements from CISPR 11 and provides important clarifications on the application of CISPR 11 for RB-WPT.
