The new version was applicable from April 1, 2007, and became mandatory on October 1, 2009. The older versions, EN55022:1998+A1 2000+A2 2003, were also phased out at that time.<\/p>\n\n\n\n<p>The most important updates to this standard are the addition of requirements for radiated emissions at frequencies above 1 GHz and the redefinition of test methods for telecommunications ports, as well as ISN parameters.<\/p>\n\n\n\n<p>According to the requirements of the new version of EN55022:2006, information technology products with a maximum internal frequency greater than 108MHz must undergo radiated interference testing at frequencies above 1GHz, with the maximum testing required up to 6GHz. Additionally, products with network and telecommunications ports must undergo mandatory conducted testing of the telecommunications ports, such as network ports (Land port, RJ45) and telephone ports (Telecom, RJ11).<\/p>","protected":false},"excerpt":{"rendered":"<p>EN55022:2006\u7248\u65b0\u6a19\u6e96EN55022:2006\u7248\uff08\u8cc7\u8a0a\u6280\u8853\u8a2d\u5099\u7684\u7121\u7dda\u96fb\u5e72\u64fe\u9650\u503c\u548c\u6e2c\u91cf\u65b9\u6cd5\uff09\u5df2\u4e8e200 [&hellip;]<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[13],"tags":[],"class_list":["post-3738","post","type-post","status-publish","format-standard","hentry","category-environmental-contries-rules"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.2 -
