标准摘要
[中文适用范围]： IEC 60153 的这一部分规定了圆形波导的直空心金属管用作电子设备中的波导。本建议的目的是为空心金属波导规定： a) 确保兼容性和@尽可能重要的@互换性所需的细节； b) 试验方法； c) 电气和机械性能的统一要求。 [外文原描述]： IEC 60153-4:2017 specifies straight hollow metallic tubing of circular waveguides for use as waveguides in electronic equipment. The aim of this recommendation is to specify for hollow metallic waveguides: a) the details necessary to ensure compatibility and, as far as essential, interchangeability; b) test methods; c) uniform requirements for the electrical and mechanical properties. This edition includes the following significant technical changes with respect to the previous edition: a) expand and revise the operation frequency range for waveguides; b) revise the allowance of aperture dimensions; c) revise the test method for aperture dimensions; d) revise the equation of attenuation.
