工业微波加热装置 - 功率输出测定的试验方法

[中文适用范围]： 本标准草案为正式出版前6周的预发布版本，可在投票期间（2026年6月5日至2026年7月17日）购买。购买后可额外获得最终出版物的红线条款版本。IEC 61307:2026规定了工业微波加热装置中，将电能转换为微波输出功率的效率，以及可用微波输出功率与工作负荷的测试方法，并涵盖运行灵活性。原则上，本标准适用于工作频率范围在300 MHz至300 GHz之间的工业微波加热设备及装置，重点聚焦于6 GHz以下的微波工业、科学和医疗（ISM）频段。本标准适用于按制造商规范进行正常操作的工业微波加热设备。本标准不适用于家用及类似用途设备（由IEC 60335-2-25覆盖）、商业用途设备（由IEC 60335-2-90和IEC 60335-2-110覆盖）或实验室用设备（由IEC 61010-2-010覆盖）。本第四版取代2011年发布的第三版，属于技术修订版。本次修订相较于上一版主要包含以下技术变更：a) 除待机与休眠模式外，还涵盖启动、待机及保持状态的功率消耗，以及其他运行灵活性相关方面；b) 对微波功率的若干方面以及A型和B型设备的处理提供了更为详细的描述。 [外文原描述]： This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2026-06-05 to 2026-07-17. By purchasing this FDIS now, you will automatically receive, in addition, the Redline version of the final publication. IEC 61307:2026 specifies test methods for the determination of the efficiency of frequency conversion from the electrical input, and of the available and workload microwave output power in industrial microwave heating installations, as well as operational flexibility. This document is in principle applicable to industrial microwave heating equipment and installations in the frequency range from 300 MHz to 300 GHz but focussed on the microwave ISM frequencies below 6 GHz. This document relates to industrial microwave heating equipment operating as intended by the manufacturer's specifications for normal operation. This document does not apply to appliances for household and similar use (covered by IEC 60335‑2‑25), commercial use (covered by IEC 60335-2-90 and IEC 60335‑2-110) or laboratory use (covered by IEC 61010-2-010). This fourth edition cancels and replaces the third edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) it covers not only the standby and hibernation modes, but also start-up, standby and holding power consumption, as well as other aspects of operation flexibility; b) more detailed descriptions of the aspects of microwave power, and handling of the A and B types of equipment.
