Upcoming ANSC C63® Standards Webinar Provides Updates on the Next Edition of ANSI C63.4 and the NEW ANSI C63.25.2

Join Industry Experts on Thursday, April 28, to Learn How These Standards Impact EMC Test Methodologies for Equipment and Site Validation


CEDAR PARK, Texas, March 24, 2022 – Active technical contributors to the American National Standards Committee (ANSC) C63 (Electromagnetic Compatibility) will present in a webinar on Thursday, April 28, from 8:00 to 9:30 am PDT to share the latest information on two key standards maintained by ANSC C63.  The two standards include the seminal ANSI C63.4 “Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz” and the new ANSI C63.25.2 “Validation Methods for Radiated Emission Test Sites, 30 MHz to 1 GHz.”    

The Working Group for ANSI C63.4 has been very active in recent years updating the current edition to include the latest EMC measurement methods.  With publication of the new edition expected in early 2023, the EMC test and measurement community will most certainly appreciate that the webinar will be covering the new test methodologies contained in this standard.  This latest edition is eagerly anticipated since ANSI C63.4 was last published in 2014, with an amendment published in 2017. 

ANSI C63.25.2 is particularly significant since it is a NEW standard that provides the latest test methodology for validating performance of an EMC test site, while addressing the frequency range of 30 MHz to 1 GHz as part of its “series” on validation methods for radiated emission test sites.  (C63.25.1 addresses the frequency range of 1 to 18 GHz; C63.25.3 addresses the frequency range of 18 to 40 GHz.)  The C63 Main Committee has approved the latest draft of this standard, and the Working Group is currently reviewing comments from the Main Committee.  During the Q&A session of the webinar, attendees are welcome to add their own comments for Working Group consideration.  

In light of the significance of these C63.4 and C63.25.2 standards to designers of electrical and electronic equipment as well as to users of commercial and in-house EMC test chambers, respectively, experts from ANSC C63 will provide an educational webinar to present the new test requirements specified in these standards. 

     Webinar moderator and ANSC C63 Committee Chair Dan Hoolihan with Hoolihan EMC Consulting stated, “It’s important to discuss these two standards together as the site validation test methods currently described in C63.4 will move to the C63.25 series of standards.  We are conducting this work in parallel so both standards may be published concurrently.  Our webinar speakers, Andy Griffin with Cisco Systems and Zhong Chen with ETS-Lindgren, along with their respective Working Groups, play an important role in making this happen.”

Webinar topics include:

·       Update on ANSI C63.4:202x - Latest Developments by Andy Griffin, EMC Standardization Subject Matter Expert, Cisco Systems, San Jose, California; Chair of ANSC C63.4 Working Group

·       Streamlining Site Validation Measurements Below 1 GHz in C63.25.2 by Zhong Chen, Director of RF Engineering, ETS-Lindgren, Cedar Park, Texas; Chair of ANSC C63 Subcommittee 1: Techniques and Development

 Mr. Hoolihan will moderate a live Q&A session with the speakers following the presentations.  More information on the webinar, including presentation abstracts, speaker biographies, and registration link, is available here.  For more information on ANSC C63, click here.  Note ANSC C63 will hold its first in-person meeting of 2022 at ETS-Lindgren’s corporate headquarters in Cedar Park, Texas, May 16 - 20.  If you are interested in attending the meeting as an observer, please contact Janet O’Neil at +1 (512) 531-2676 or janet.oneil@ets-lindgren.com.
